O-Rings & Hydraulic Seals

Metallic

Teflon Encapsulated O Rings

A teflon jacket gives the seal chemical inertness, whilst the viton or silicone core gives the seal resilience and energises the seal.

Quad rings

When squeezed upon installation, Quad Rings seal with 4 contact surfaces—2 small contact surfaces on the top and bottom. This contrasts with the standard O-ring's comparatively larger single contact surfaces top and bottom.Quad Rings are most commonly used in reciprocating applications, where they provide reduced running and breakout friction and reduced risk of spiraling when compared to O-rings.

Square

The physical sealing performance of square rings in static applications is superior to that of O-rings, however in dynamic applications it is inferior to that of O-rings. Square rings are usually only used in dynamic applications as energizers in cap seal assemblies.
