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.
