VITON Quad Ring From China

Product Details: Viton Quad Rings, also known as X-Ring or Quad-Ring seals, are four-lobed seals with a specially developed sealing profile. They are made from a wide range of elastomer materials, including Viton/FKM, which allows them to seal practically all liquid and gaseous media. These seals have a double sealing function compared to standard O-rings and are suitable for both static and dynamic sealing applications. The four-lobed design provides twice the sealing surface of an O-ring, requiring less squeeze to maintain an effective seal. They are measured by their cross-section and inside diameter, similar to O-rings.

Pros:
– Provides twice the sealing surface of a standard O-ring, reducing the need for h…
