Why do hydraulic quick couplers leak?

Why do hydraulic quick couplers leak?

Most hydraulic hose leaks are caused by using the wrong type of fitting or installing them incorrectly. Additionally, if an O-ring is missing or damaged or if over-under-torquing the connections has occurred, the seal may not be aligned correctly and even worse, the threads might be damaged.

Can hydraulic couplers be rebuilt?

Repair kits are available depending on the root cause of the problem, such as whether it leaks when connecting or disconnecting. There are seal replacement kits available for the male couplers but not the female. If leaking when connected, you can replace the seals on the male couplers and that may fix the problem.

Can a hydraulic fitting be used with an O ring?

They have lived up to the task, but because O-rings provide such a simple solution, many designers and technicians take them for granted and may even ignore common sense when using O-ring fittings. Consider a hydraulic fitting with a Buna-N O-ring that has been stored in a parts bin for who knows how long—probably years.

Is the shelf life of an O ring always the same?

A common misconception is that fittings made of metal last forever in the box, provided they are not stored in a corrosive environment. Although that is true, to a point, if an unused fitting has an O-ring, its shelf life is only as long as that of the O-ring.

How is an O ring attached to a JIC SAE flare?

This straight thread connection uses the same threads as the JIC 37° . However the 37° flare has been removed and an o-ring has been added. When mated with a female o-ring boss port the o-ring is trapped in a special tapered counter bore to affect the seal.

What kind of O rings are used in engines?

O-rings made of Buna-N are frequently used in engines, gearboxes, and many other applications, ranging from shower heads and garden hoses to pumps in aircrafts. Buna-N O-Rings are frequently used as face-to-face gaskets or as a shaft seals, and easily allow both rotary and linear movement.

Fluorocarbon FKM & Viton® O-Rings: Chemical resistant Fluorocarbon FKM O-Rings exhibit exceptional resistance to chemicals, oils, temperature extremes, low compression set, low gas permeability and excellent aging characteristics. It has a good resistance to ozone, high temperatures]

How does an O-ring face seal fitting work?

Steel O-Ring Face Seal Fittings (ORFS) O-ring face seal adapter fittings use a straight thread and have a machined groove in the face of the male fitting to accept an O ring (of either Buna N or Viton material). This O-ring is compressed against the flat face of the female fitting for a leak proof connection.

What are the different sizes of O rings?

We supply O-Rings and seals in any size, material, durometer, color, and specialty performance.
