PTFE Cap Seals
The Cap Seal consists of a ring of PTFE positioned on either the OD or ID of an O-Ring energiser.
These seals are designed to offer low friction, bi-directional, sealing and can normally be installed in a closed type groove.
This type of seal can combine a variety of elastomeric and thermoplastic material properties to allow a wide range of application parameters to be catered for.
Features & Benefits
Designed to install into single piece groove
Reduced dynamic & break out friction compared to standard O-Rings
Stability provided by the cap geometry
Various materials can be combined suiting the seal to the application
As dynamic seals
Typically in reciprocating applications, where friction is a concern
