Non-lined Fittings

End Fitting Specification

  • BS4825 Pt 3 (UK)
  • ASME BPE-a-2007 (USA)
  • DIN32676 (Europe, DN Sizes)
  • ISO 1127 (Europe) (Non Standard, Specials Only)

Temperature and Pressure Ratings

For Standard Clamp and Standard (EPDM) Gasket

  • Pressures up to 16 Bar (230 psi)
  • Temperatures up to 120˚C (250˚F)
  • Higher Pressures and Temperatures with Special Clamps and Gaskets

End Fitting Materials

  • Fittings in AISI 316L = EN 1.4404 = BS 316 S11. Internal Bores all Electropolished to <15µin Ra (<0.375µ mtr).
  • Ferrules, most in Grade 304 SS, some sizes in Grade 316L SS

Outlet Diameters (Inch pipe sizes only)

The outlet diameters as listed are in accordance with BS4825. The ASME specification, however, requires these diameters to be 0.005” (0.125mm) less in each case. An Outlet Diameter tolerance of +0.000 -0.005” has therefore been applied, so that the same fitting satisfies requirements of both specifications.
