Description
Pelican Worldwide CG-G-300-E is a 3″ EPDM gasket for cam-and-groove (camlock) couplings, sold as a 5-pack. The gasket seats in the female-coupler groove of Part B, Part C, and Part D 3″ couplings to seal against a mating male adapter. EPDM is the standard elastomer for water, glycol, dilute acids and bases, ketones, alcohols, and hot air — services where Buna-N is not chemically compatible.
