When to Replace your Hydraulic Hose

Hydraulic hoses are the lifelines of almost all construction equipment. When a hydraulic hose breaks, it can derail production schedules instantly costing you time and money.  While planned maintenance is a part of any quality operation, Should a failure occur that is unexpected or shuts down production completely, these expenses are often much higher cost than planned maintenance. Like auto tires, all hydraulic hoses have a shelf life.   Depending on the type of hose, after 4 to 5 years the rubber begins to break down and you can expect to see visual cracking and weeping around the couplings. If you are using a lower quality hose, that can be even sooner.

There is no need to replace the hose if there are no signs of leakage, abrasions, cracks or twisting. A visual inspection can catch many potential hose failures. In many (but not all) cases, there are indications of an impending failure. Wetness or leaks, cracked rubber, loss of flexibility or worn rubber are all signs of a current or future hydraulic hose failure. There is really no reliable way to tell how long a hose assembly will last once these symptoms are noticed. That's why we recommend doing inspection of your your hydraulic hoses and assemblies on a regular basis.

There are many causes of hose failure. It is generally accepted by the industry that approximately 80% of hydraulic hose failures are caused by external damage, primarily abrasion.  In our experience, the most common cause of abrasion is hose assemblies rubbing on each other or surrounding surfaces. That's why we recommend Poly Wrap or Protective Sleeve for your hoses in abrasion prone areas. Plastic guards or coil sleeves protect hose from exposure to water, air, gasoline and hydraulic fluids. They are typically fitted after the hose is installed. Textile or nylon sleeving helps protect hoses from abrasion, either inside the equipment or in areas where hoses are likely to rub against one another.

We recommend you inspect all your hydraulic hoses regularly and keep a log of trouble spots on your equipment. It is very important that you follow bend radius, twist, orientation, and storage to maximize your hydraulic hose life. But recognize that all hoses have a limited shelf life and be prepared to replace them at the right time to maximize both safety and productivity.

At The Hose Company, our goal is to help our customers find the products they need at a price they can afford. To accomplish this we have a dedicated and experienced team of hydraulic professionals ready to assist you in person, at our Matthews, NC facility,or online at info@thehosecompany.com.

5 minute inspection or 2 hours of down time?

Time and time again customers ask us how long hydraulic hose assemblies can be expected to last in the field.  The short answer: Not as long as you want them to the long answer: Much longer if you take a few minutes to look for wear and tear clues.

The Hose Company would like to offer 4 tips to help you extend the life of  hose assemblies on hydraulic equipment.

#1. Set up a preventive schedule - and follow it regularly
For most applications, a simple visual inspection once a month and preventive replacement of hoses every year or two is adequate. 80% of hose failures are attributable to external physical damage through pulling, kinking, crushing or abrasion of the hose.  All the external damage can typically be visually checked. 

#2 Keep log of hose repairs - especially frequent replacements
Use this log to estimate how long hoses last in your application. According to the Society of Automotive Engineers (SAE), the shelf life of bulk rubber hose is 10 years from the date of manufacture. Note the manufacturing date on the lay-line and if the hose is close to 10 years old consider a preemptive replacement.

#3 Watch problem areas closely
Critical hose assemblies may be those that are close to the equipment operators and whose failure could result in injury or would cost a great amount of damage. Keep an eye out for clues a problem is developing.

#4  Always approach with caution
When inspecting the equipment, never touch pressurized hoses with your hands, not even with gloved hands. If you are looking for a pinhole leak, use a piece of cardboard or wood to locate it, NEVER run your hand over the hose to find it.  Hydraulic oil injection injuries are very serious and can result in amputation or even death.  

Clues to potential problems

  • Oil leaking around fittings or along the hose
  • Crushed hoses                                                                    
  • Abrasion- exposed wire reinforcement
  • Significant outer cover damage
  • Twisted or Kinked hoses
  •  Cracked or corroded fittings                                                                    

Purchasing a new hose assembly is usually many times less expensive than the cost of clean up after the old hose breaks, not to mention the potential damage to different  and expensive components of your system, down time and the potential for injury. The Hose Company can provide custom hose assemblies for you, or bulk hose for the do-it your self hydraulics person.

In the case of hydraulics it is true that an ounce of prevention
cost much less than the pound of cure.

Tips for Handling Hydraulic Leaks

9 Tips 

According to government reports, hydraulic fluid leaks account for almost 14% of the more than 700 million gallons of petroleum products entering the environment each year. If you are serious about your hydraulic equipment running well, and being environmentally safe, consider these nine Hydraulic DO's to handle leaks.

#1 Do resolve a leak issue as soon as it is noticed

Even the untrained eye can easily spot an external leak.  Don't ignore it. Even a minor drip could be a sign of a more serious problem in your hydraulic system, and can cause performance issues and inefficiencies. Resolve the issue as soon as possible. 

#2 Do use gloves when working with hydraulic leaks 

Don't use your hand to check for leaks. Hydraulic fluid reaches temperatures of 300 degrees F or higher, which can quickly result in a serious burn. In addition, taking a pinhole leak of high velocity fluid to your hand can have devastating outcomes.  Injuries such as these result in the need for immediate medical attention, possible amputation, and industry safety violations. Be careful.

#3 Do keep open flames away from the leak 

Keep all open flames away from leak points. People often forget that pinhole leaks can create mist-like "clouds" of flammable vapor. Common hazards include lit cigarettes, the use of lighters for illumination and welding or cutting torches being used close by. Safety First, repair second.

#4 DO Depressurize the system

Always depressurize a hydraulic system before inspection. This applies even if you only see a slow fluid drip on the ground. Depressurization minimizes the chances of hydraulic fluid erupting from a machine component during inspection.  Trapped fluid and back pressure can still be present after the system is turned off. Approach the system carefully even when it is off.

#5 Do check your lubricant

Eighty percent of machine and equipment stoppages and component failures are caused by contaminated lubricants. Oxidation caused by overheating and contamination by dirt, water and wear metals are two of the biggest causes of hydraulic system failure and can lead directly to leakage problems. Dropping the fitting on the ground before reassembly can introduce contamination into the hydraulic system. Protect your work space.

#6 DO clean connections and fittings

Remember to clean the connecting ends before replacing or reassembling a fitting. This helps prevent dirt and metal flakes from entering the hydraulic system. Installing a conical washer between the joint's nose and flare can eliminate leaking flare joints on JIC 37 flare and will decrease potential issues.  Connectors that incorporate an elastomeric seal, such as a UN-O-ring, BSPP, ORFS, and SAE 4-bolt flange, offer far superior seal reliability. For leak-free reliability, it's best to replace pipe-thread connectors with a type that incorporates an elastomeric seal, where possible.

#7 Do replace fittings and Orings as needed

O-rings should always be changed even if you are reassembling a reusable fitting. O-rings are susceptible to cracks that can ruin seal integrity upon reassembly. It is always less expensive to replace a fitting than to replace the entire machine.


#8 Do tighten and torque correctly

A common cause of leaks from 37° flare joints and compression-type tube fittings is incorrect torque. In the case of flare joints, insufficient torque results in inadequate seat contact, while excessive torque can result in damage to the tube and connector. In the case of compression joints, incorrect torque can result in too much or too little "crush" on the ferrule. Fluid leaks are occasionally the result of a loose nut. This problem can be easily corrected by tightening the nut. Check that you don't over-tighten when you are done.

And perhaps the most important way to handle hydraulic leaks-

#9 DO set up a maintenance schedule

Hoses and fittings that are inspected regularly tend to create fewer emergencies.  Check for cracks, blisters, leaks.  Service filters and keep the machinery clean.  Watch for hydraulic drips and take the time to locate the leak, before it becomes an environmental and economic problem. 

Hydraulic leaks cost millions of dollars annually, and our environment an unknown toll. 
Let's work together to lower the costs to you, and to our planet.

How did we get BSPP and NPT: Some Hydraulic History

In the nineteenth century, many different types of screw threads were required for hydraulic and pneumatic circuits as well as fastening components. As a result, manufacturers started to devise their own fastening systems. This resulted in compatibility problems.  

The English mechanical engineer and inventor, Sir Joseph Whitworth devised a uniform threading system in 1841 to address the incompatibility problem. The Whitworth thread form is based on a 55-degree thread angle with rounded roots and crests.  

This form was selected as a connecting thread for pipes, which was made self sealing by cutting at least one of the threads on a taper. This became known as the British Standard Pipe thread (BSP Taper or BSP Parallel thread). The Whitworth thread is now used internationally as a standard thread for jointing low carbon steel pipes.

NPT Evolves 
In America, William Sellers set the standard for nuts, bolts, and screws which became the National Pipe Tapered Thread (NPT) in 1864. His 60-degree thread angle helped form the American Industrial Revolution, and later became the American National Standard. 

The best known and most widely used connection where the pipe thread provides both the mechanical joint and the hydraulic seal is the American National Pipe Tapered Thread, or NPT. NPT has a tapered male and female thread which seals with Teflon tape or jointing compound.

And now you know.

5 tips to pre-empt indigestion while repairing Hydraulic Hoses

    If you have been in the hydraulics business for a while you've heard the acronym S.T.A.M.P.E.D. We thought for the new year we would break it down to an even simpler reminder. If you keep these five tips in mind you will save yourself repeat work and undue stress.

Pressure- Choose a hose that has suitable working pressure for the machine application.  Read the layline on the hose and duplicate as closely as possible to the hose type and pressure rating.  If the rating can't be read do to UV fading, or age wear, find the repair manual and double check.  It will be worth your time now, to save on premature repairs.

Temperature- Match the fluid viscosity to the operating temperature.  You will achieve maximum component life if you duplicate the original grade of fluid viscosity to the operating temperature range of the hydraulic system.

Usage Fluid Confirm you are using hydraulic hose compatible to the fluid being pushed through the hose.  Not all hose is meant for all applications.  When in doubt, check with your supplier  to confirm the hose being ordered will work with the fluid in the application.

Material- Select the hose coating to support the environment where the hydraulic hose will be exposed. If there is potential for damage from pinching or crushing, consider adding protective sleeving over the hose.  It will prolong the life of the hose and keep you from premature repairs.

Size-  Examine the current inner/outer diameter of the hose you are replacing.  Make sure and replace with comparable size.  This will protect against unwanted friction and flow restriction. Friction creates heat, heat creates back pressure increase and if the flow rate is reduced, cutting down on reliability and productivity in addition to potentially damaging other system components.  

If you keep these five tips in mind during your repairs you will cut down
the need for stress remedies.
