Care must be used to select a body material, arm material and gasket material that is compatible with the material being transferred through the coupling. Damage to the tube can be result if they are swaged or crimped. A shank that is specifically designed for swaging or crimping is recommended if the assembly is to be swaged or crimped. For maximum coupling retention, an interlocking collar must be used.
Cam and Groove couplings must never be used for steam service
