VITON Quad Ring From China
Product Details: Viton Quad Rings, also known as ‘x’ profile O-Rings, are four-lobed seals with a specially developed sealing profile. They are made from a wide range of elastomer materials, allowing them to seal practically all liquid and gaseous media. These seals are used in various static and dynamic sealing applications. The four-lobed design provides twice the sealing surface compared to a standard O-ring, requiring less squeeze to maintain an effective seal. X-Ring parting lines are between the lobes, away from the sealing surface, eliminating leakage issues from parting line irregularities. They are measured by their Cross Section and I.D., similar to
O-rings, and can be used in narrower grooves as well as standard O-ring grooves[2][4].
Pros:
– Provides twice the sealing surface compared to a standard O-ring, requiring less…
