Quad Ring Seals are four lipped seals with a specially developed sealing profile. A wide range of elastomer materials for both standard and special applications allows practically all liquid and gaseous media to be sealed.
Quad Rings/X-Rings have the following advantages compared to an Oring:
- Avoids twisting in the groove. Due to its special profile, the seal does not tend to roll in the groove during reciprocating movement.
- Low friction.
- Very good sealing efficiency. Due to an improved pressure profile over Quad Ring Seal cross-section, a high sealing effect is achieved.
- A lubricant reservoir formed between the sealing lips improves start up.
- Unlike an O-Ring, the mold line flash lies in the trough, between and away from the critical sealing lips.
