PTFE gaskets

Overview

PTFE gaskets

(polytetrafluoroethylene)

PTFE gaskets offer the ultimate chemical resistance and purity. PTFE is almost totally chemically inert, and offers versatility in application due to being highly flexible, strong, and able perform in extreme temperature conditions.

These high performance sanitary gaskets have been designed to achieve a smooth bore, contamination free fluid path under clamping compression.

Features and benefits

  • Designed in accordance with ASME-BPE standards
  • USP Class VI compliant and animal derived component free (ADCF)
  • Compliant with FDA regulations CFR 21 177.2601
  • Lot numbering enables product traceability
  • Performs in extreme temperature conditions. Ranging from -350 °F to 450 °F
