Pipe, Tubing, Hose, and Fittings

Twist-Claw Hose Couplings for Air and Water

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

Spring-Lock Twist-Claw Hose
Couplings for Air and Water

Couplings have a spring-loaded locking sleeve that automatically locks into place to prevent accidental disconnection. The identical claw-style head connects to another spring-lock twist-claw hose coupling with a quarter twist.

Extra-Large Twist-Claw Hose
Couplings for Air and Water

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

Large Twist-Claw Hose Couplings for Air and Water

Also known as Chicago and universal couplings, these have identical claw-style heads and connect by being pushed together with a quarter twist.

Interlocking-Clamp Hose Fittings for Steam

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.

Cam-and-Groove Hose
Couplings for Abrasive Material

Made of ductile iron, these couplings are tough enough to handle sand, cement, and other abrasive solids and slurries. Use their cam-and-groove fittings to quickly connect and disconnect medium- to large-diameter hose lines.

Tight-Seal High-Torque Bolt Clamps for Firm Hose

Clamps offer extra holding power in high-torque applications.
