O-Rings are a torus, or donut-shaped ring generally molded from an elastomer. An O-ring prevents the loss of a fluid or gas over a wide range of temperatures, pressures and tolerances. Applications for these types of seals can be used in static or dynamic applications in rod, piston and axial configurations. Standard sizes per AS568 are available as well as custom sizes from micro seals to infinite inner diameters.
Benefits:
Encapsulated O-Rings are specifically designed to address the problem of sealing the most hostile chemicals and extreme temperature applications. Encapsulated O-Rings consist of a solid or hollow elastomeric core encapsulated in a PTFE FEP or PFA sheath. To ensure optimum chemical resistance XMEK offers a unique compound with an extremely low compression set. The elastomeric core may be fluorocarbon or silicone rubber. Solid core encapsulated O-Rings are generally used in static applications. Hollow silicone core encapsulated O-Rings are commonly used in applications where lower sealing force is required as in semi dynamic applications. The encapsulated O-Ring offers an effective solution for many difficult applications. Maximum operating temperature for FEP is 205°C (400°F) and for PFA 260°C (500°F).
Encapsulated O-Ring dimensions comply with International O-Ring dimensional standards. The encapsulation does not increase the cross section compared to a standard elastomer of the same size.
XMEK provides a wide variety of X-RINGS in many materials. X-RINGS are four-lipped seals and provide excellent sealing characteristics for a broad range of applications.
These seals reduce friction and provide stability in application.
