X-rings / Quad Rings

Also known as Quad-ring® seals or four lobbed seals, X-rings are available from Novotema in a wide range of elastomer materials to suit any application.

Used in both static and dynamic sealing applications, X-rings can be retrofitted into existing O-ring grooves. The four lobbed design provides twice the sealing sealing surface in comparison to a standard O-Ring, preventing the seal from twisting and rolling and thus avoiding spiral failure often seen when O-rings are used in reciprocating applications.

X-rings can offer a reduction in friction than conventional O-rings and because they need less compression for effective sealing, they are able to obtain a prolonged seal life. X-rings can be manufactured to standard O-ring sizes, as well as custom sizes for specific applications in a number of industries including oil and gas, chemical processing and medical.
