90˚Elbow Cam & Groove Fittings (PTFE Lined Only)
90˚ Elbow Integral PTFE lined Cam & Groove Fittings are available for sizes 1”, 11/2” and 2” - see 90˚ Elbow Fittings.
Notes: For Integral PTFE Lined Fittings Only
FEP Gaskets require higher clamping forces to flatten the Seal and make the joint. This is made easier by “pre-setting” these gaskets by clamping Polypropylene Cam Male Inserts to the assembled fittings, which must then be kept in place during storage, until use.
Any Customer’s Own “Special” Gaskets must be pre-supplied to Aflex for special assembly and testing of hose assemblies, to ensure suitability.
