Bevel Seat Gaskets (40BS)
- Available in both Buna and Teflon®
- PTFE (Teflon®) is a material subject to plastic flow. When cycled through heat and then cooled down in process lines, PTFE gaskets will not return to their original configuration. They will continue to compress as the cycling continues. This plastic flow will allow leakage if clamp torques are not maintained.
- Refer to Compound Selection Guided for compatibility information.
