Use of fluorocarbon FKM o rings, under high pressure

O-ring is widely used in the joints of various hydraulic and pneumatic pipe joints, cylinder faces and flange faces. For the O-ring used in the movement, when the working pressure is greater than 9.8Mpa, if it is pressed in one direction, a back up ring is set on the other side of the O-ring in the direction of pressure. In case of two-way compression, place back up rings on both sides of the O-ring.

Wedge type back up ring can also be used to reduce friction. When the pressure liquid is applied from the left, the right back up ring is pushed up, and the left back up ring does not contact the sealed surface, so the friction is reduced.

In general, the use of retaining ring will increase the friction of the sealing device, and wedge type back up ring is of great significance to reduce this friction.

For the fixed O-ring, when the working pressure is greater than 32Mpa, the back up ring is also required.
