PTFE lined and flared

Introduction

Advantages are - unrestricted clean flow of fluids, no fluid entrapment areas, and all PTFE wetted surfaces internally. Available as standard, stocked fittings in the listed sizes, or in other sizes to special order.

End Fitting Specifications

  • ASME BPE
  • DIN32676
  • BS4825 Pt 3 - equivalent to ASME BPE
  • ISO 1127

End Fitting Materials

  • Fittings in Grade 316L SS (= BS 316 S11 = EN 1.4404)
  • Ferrules, most in Grade 304 SS, some sizes in Grade 316L SS

Temperature and Pressure Ratings

  • Pressures up to 16 Bar (230 psi)
  • Temperatures upto 120˚C (250˚F) with EPDM Gaskets
  • Temperatures up to 180˚C (356˚F) with PTFE, Silicone or Viton Gaskets
  • Higher Pressures & Temperatures possible with Special Clamps and appropriate Seals.

Note: The inside lip of the Aflex flared face design is hot formed to a square edge. This prevents a gap for fluid entrapment between the rubber seal and the sealing face. Other suppliers designs have rounded edges, which opens a gap for fluid entrapment.

'Beaded' Triclover Fittings

This fitting design is available to special order. No separate seal is required for this design, eliminating any seal compatibility problems.
