??To Hydraulic O-rings to maintain good results, understand the hydraulic O-ring hardness, long-term use of nuclear tests we learned under what circumstances the best use of what hardness hydraulic O-ring.

??Hydraulic O-ring hardness is generally 50 to 90 Shore A, when the pipeline pressure is greater than 1.0MPa 150LB or equal to, the O-rings should be embedded in the metal groove, preventing the O-ring with the hydraulic pressure changes and squeezed pressure deformation.

??When the hydraulic valve low pressure pipe, in order to save environmental protection, should preferably be 50 to 70 Shore hydraulic O-ring. When the hydraulic valve high pressure piping for safety point of view, should be recommended to select Shore hydraulic O-ring 70 to 90.

??High-pressure hydraulic O-ring prone to breakage. Hydraulic O-ring that is under high pressure role, after a long period of high pressure gas molecules penetrate inside, when the O-ring instantly reduce the external pressure, internal high-pressure gas molecules are easily diffused rapidly bursting O-rings, such as seat at O-ring seal, when the ball valve for rotation is turned on, the internal pressure relief valve chamber instantaneous media, the loud voice, this time, remove the O-rings have been found broken, indicating that the ball valve sealing performance has lapsed. Thus, in this case, it is recommended to use the seat sealing tightness caused by high O-rings, or timely replacement O-ring seal in order to ensure the normal operation of the pipeline valve.

??Xinhua Xu Hydraulic O-rings can be customized, hydraulic O-rings at high frequencies it has limited life and must be replaced regularly to ensure production safety.
