Original seal Star seal ring x ring
The star seal ring is a self-tight seal type double-acting sealing element. It adopts a four-lip seal and has a shape similar to X. It has improved and improved performance on the basis of the O-ring. Its standard size is the same as that of the O-ring. The ring is the same, it can replace the O-ring in most occasions. The difference is that the structure of the star ring makes it more suitable for dynamic sealing. Mainly because of its special star-shaped section, it will not roll and twist in the groove during reciprocating motion; the radial pre-compression required is relatively smaller than that of the O-ring, the friction generated is small, and the wear The amount is also small; compared with the O-ring, its flash position is in the recess of the section, and the section has a better pressure distribution, which can obtain a good sealing effect; a lubrication volume is formed between the sealing lips of the star ring. The cavity has a smaller frictional resistance, which improves the starting condition.
