PTFE O-rings (Solid) | Plastik Solutions

Overview

Solid PTFE o-rings machined from rod or compression-moulded. Virtually inert to all chemicals, the widest temperature range of any o-ring material, but no elastic recovery — relies on initial compression and is best for static sealing. For dynamic applications use spring-energized or encapsulated variants.

Specifications

Core material	Solid PTFE (no core)
Service temperature	−200 to +260 °C
Hardness	—
Standard sizes	Metric and imperial (AS568) on request — bespoke sizes available

Typical Applications

Static face seals in chemical-resistant flanges
Pure-fluid applications (semiconductor, pharmaceutical)
Where no elastomer or spring metal can be tolerated
Single-use or low-cycle sealing
Backup rings paired with elastomer o-rings
