Hydraulic Adaptor, 3/4"JIC Cap

Hydraulic Adaptor, 3/4"JIC Cap

A reliable hydraulic cap designed to seal unused JIC connections, the 304CX12 Hydraulic Adapter Cap provides a secure way to plug and protect 3/4" JIC fittings when a hydraulic line or port is not in use. Featuring a 37° JIC flare seat, this solid cap creates a dependable seal against the mating fitting, helping prevent leaks while also keeping dirt and contaminants out of the system. It’s a small but important safeguard—because hydraulic systems work best when everything inside them stays clean and contained.
