How To Do When Your Hydraulic Fitting Leaks?
Sep 01, 2017

        For the leakage of hydraulic equipment, from small businesses to global enterprises, we have seen and heard all this. Let us know some misunderstandings. Why do not you do when you find out if the hydraulic fittings leak.


Do not check the leak by hand. The hydraulic fluid reaches temperatures above 300 ° F and can cause severe burns. In addition, the high-speed fluid pinhole leak to your hand will have devastating consequences. These leaks can be more than 600 feet per second and are known to be injected through the skin, including skin covered with thick leather gloves. When the distance between the fluid source and the skin reaches four inches, the penetration of the skin has been recorded and occurs at a pressure as low as 100 psi. These injuries lead to immediate medical attention, possible amputation and violation of industry safety behavior.


Do not just torque (tighten). Liquid leakage is occasionally the result of loose nuts. This problem can be easily corrected by tightening the nut. However, we often see people overtake. This damage is complete and is one of the most common causes of pipe leaks. Be sure to evaluate the accessory before you can tighten it.


Do not let the system pressurize. The hydraulic system must be decompressed before inspection. Even if you only see the slow liquid dripping on the ground, this also applies. Decompression minimizes the chance of hydraulic fluid ejected from the machine parts during the inspection. Note: After the system is closed, there may still be trapped liquid and back pressure.


Do not use different accessory types instead to save time / money. Make sure you replace the accessory with exactly the same accessory type, even if it takes longer. Grab a similar fitting and try to get it to work because it is available is a secret of failure. When you wait for the right part, the downtime you encounter is well worth your long time to save and money.


Do not always blame the accessories. Droplet may not be a leak. The loss occurred at the lowest point. When the fluid may drip from the fitting, the actual leak may be in other parts of the system.


Do not reuse O-rings. You should always change the O-ring even if you reassemble the reusable accessory. O-rings are susceptible to cracks that break the integrity of the seal when reassembled.


Do not forget to protect the open system while repairing the leak. We've been seeing it all the time. People remove the accessories to correct the leaks, and only place the parts on the floor before reassembling them. This may introduce contaminants into the hydraulic system while fixing the leak. This is a bad practice that can reduce the life of your equipment.


Do not forget to clean the connection before replacing or reassembling the fitting. This helps prevent dirt and metal chips from entering the hydraulic system. It is known that these particles completely destroy expensive hydraulic machinery.


There is no open fire to keep all open fire away from the leak. People often forget that pinhole leaks can produce flammable "cloud" flammable vapors. Common hazards include lit cigarettes, use of lighter lighting and welding or cutting torch close use.


Do not ignore it. Even a slight leak may be a more serious problem in the hydraulic system, which can lead to performance problems and inefficiencies. Solve the problem as soon as possible.
