Industrial O Ring for Oil Resistance Rubber X Ring Pipe Fitting Rubber o ring seal
Quad-rings are four lipped seals with a specially developed sealing profile. It has a double sealing function as compared to O-ring. A wide range of elastomer materials for both standard and special applications allows practically all liquid and gaseous media to be sealed. The choice of a suitable material is determined by the temperature, pressure and media. They are vulcanized as a continuous ring. Quad-rings are supplied to the American Standard AS 568 A.
Advantages of using Quad-ring:
Avoid twisting in the groove.
The seal does not tend to roll in the groove during reciprocating movement.
Low friction. It requires less radial squeeze than a comparable O-ring.
Less squeeze mean less friction, less wear, and thus a longer service life
Very good sealing efficiency. Due to it special profile, a high sealing effect is achieved.
A lubricant reservoir formed between the sealing lips improves start up
O-Rings, provide greater sealing efficiency and lower friction than a traditional O-ring. The multi-lobe (Quad) design resists rolling in dynamic application preventing spiral failure. The multi sealing points also reduce the amount of force needed to seal and extends the life of the seal.
O-rings are offered in AS568 and Metric sizes.
O-Ring Advantages
1. Deeper o-ring groove means lower diametrical squeeze, which means dynamic sealing can be acheieved with less friction
2. Greater sealing capacity but with a groove for lubrication, aiding dynamic sealing applications
3. Greater stability for dynamic applications. The x-ring resists roll much better than an o-ring
More resistant to spiral failure
