Product Feature Details

The sealing function is enabled by the stress generated when this product is installed to the groove and compressed moderately.
This product is easier to install than any other packing, takes up less space, and can be done the same way by anyone, and its self-sealing action provides stable sealing performance even under high pressure using only an O-ring.
It can be installed with a small amount of compression (squeeze) and has relatively low kinetic frictional resistance for higher efficiency.
It does not cause overtightening of nuts when used for fixing.

Principle of action
Fig. 1: When an O-ring seals a fluid with no or low pressure, the seal is maintained by a squeeze equivalent to a percentage of the cross-sectional diameter of the O-ring.
Fig. 2: As shown in the figure, when the pressure of the fluid increases, the squeezed O-ring in the groove seals by self-sealing action, being pushed from the pressure side and leaning to one side.
Fig. 3: If the pressure increases further and exceeds 10 MPa, the softness of the rubber will cause the O-ring to be damaged by protruding into the clearance.
Fig. 4: To prevent this, leather or fluoropolymer backup rings are attached to both sides of the O-ring when the pressure is on the opposite side or both sides of the pressure direction.

Cautions and Prohibitions

Cautions

The dynamic O-ring smooths the sliding metal surface finish. (It should be about 1.5S.) The inside of the groove should be about 3S.
If the reciprocating sliding surface has holes, etc., take care to protect them.
Do not use more than 2 O-rings in the same location.
Pay attention to the groove design.
If the O-ring breaks down, it will suddenly leak and cause an accident, so be sure to replace it at the end of its useful life for dynamic applications.
Due to its rubbery nature, it will age in the air, so care must be taken when storing it.
