FAQ
What are O-ring hydraulic fittings?
O-ring hydraulic fittings are special fittings that have O-rings on the metal face of the fitting to stop leaks or to reduce damage to the metal face after it has been crushed against each other.
What are hydraulic O-rings made of?
As a critical section of the fitting seal, O-ring material requirements are also very strict, where the most commonly used materials are PTFE, Viton, Neoprene, EPDM Rubber, Silicone and Nitrile Rubber,etc.
What are the advantages of O-ring hydraulic fittings?
The advantages of O-ring fittings are significant; they reduce the possibility of leaks, minimize damage to threads, can tolerate pressure and high temperatures, and are easily replaced and repaired.
What are the disadvantages of O-ring hydraulic fittings?
Although O-ring fittings can bear high temperature, there is still a limit range, and once it exceeds this range, the O-ring inside may melt. Moreover, if the O-ring is dropped or installed improperly during the process of assembly, it will cause thread damage.
How are O-ring hydraulic fittings measured?
When measuring the threads of O-ring fittings, the inner and outer diameter of the threads can be measured with the help of appropriate tools. And the O-ring should be placed on a platform and then go to measure the inner diameter, outer diameter and width of its cross section.
What do O-ring fittings used for?
O-ring fittings are widely popular because of its many benefits, and they are used eagerly in many fields. For example, construction industry, chemical industry, agriculture, etc.
What is the difference between ORB and O-ring fitting?
O-ring hydraulic fittings are similar to ORB fittings in that they both have O-rings, but the O-ring of the O-ring fitting is located in the end of the male thread’ s groove, and the O-ring of the ORB fitting is located at the the male thread’ s end.
What causes O-ring failure?
Although O-rings are convenient to operate, a series of factors such as size discrepancy, wrong material selection, improper installation, high temperature, chemical erosion, and so on, can cause failure in use, resulting in leakage or damage to the fittings.
Do JIC fittings have O-rings?
JIC hydraulic fittings can generally rely on their own design to form a direct seal, but O-rings can also be attached to enable the fittings to be sealed more tightly and to put a lower chance of leakage.
Can you reuse the O-ring fittings？
It is possible. Under reasonable use, O-ring fittings can be used for a long time, and if there is no damage or other problems, they can be used many times, but there is a possibility that the sealing ability will be reduced.
