Camlocks are often referred to as Cam and Groove Couplings.This is because they are engineeres with grooves that allow the vari ous styles to fit together creating a tight seal.Their simple structure and easy operation make them very popular.Camlocks are con nected by simply opening the coupler arms and inserting the adaptor into the coupler.As the arms are pushed down to the sides,the two connectors are forced tightly together creating the bonded seal on an internal gasket. Camlocks come in a variety kf materials:stainless steel,aluminum,brass,polypropylene,nylon. Standard 1.MIL A-A-59326 Cam&Groove couplings are made in compliance with A-A-59326(old version called MIL-C-27487)specification. 2.EN14420-7(DIN2828) The European standard EN 14420-7:2004 replaces DIN 2828,witch was applied to cam&groove couplings maunfactured to A-A-59326A.A flat thread seal has been added to the female threaded parts,and a smooth hose shank has been added for assembly with DIN 2817 safety clamps.
