Couplings have an identical claw-style head that connects to another twist-claw hose coupling with a quarter twist.

Couplings are only compatible with other extra-large twist-claw hose couplings. Use with tools and equipment up to 2 pipe size.

Also known as ground-joint couplings and boss couplings, these fittings are designed for high-pressure steam applications up to 600 psi. Insert the barbed end of the fitting into hose, then position the interlocking clamp over the hose and bolt into place. The clamp firmly grips your hose as it locks into the ring of the barbed end, creating a leak-tight seal.
