Our aluminum cam-locks are manufactured from aluminum alloy 384 (JIS grade ADS12) and feature type 316 stainless pins, forged brass handles, and plated steel finger rings. Additionally, G65C & G65E cam-locks feature a collar that, when used with G3F crimp ferrules, locks the coupling to the ferrule for extra fitting retention in sizes 2", 3", 4", and 6". G65C & G65E fittings can be crimped or clamped depending on customer preference. G65 couplings fit Commercial Item Description (CID) #A-A-59326B for sizes 3/4" to 6" and will interchange with other couplings that meet this specification. No government standard has been established for 1/2", 8" and 10" so different manufacturers' couplings may not interchange in this size. Female couplers are supplied with locking clips and standard gaskets are rated to 105°C (221°F). Please note, cam-locks should not be used with compressed air or other compressed gases.
