About Measuring Fittings

Measure the threaded ends of your fittings to identify their pipe size, thread size, schedule, and thread type. Then, find compatible components.

Hose 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.

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.

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.

Double Grip-Lock Hose Couplings for Air and Water

Also known as Thor couplings, these have two locking points to give you twice the gripping power of standard grip-lock couplings. They consist of a plug and a socket that connect with a quarter twist.

Grip-Lock Hose Couplings for Air

These couplings have a lower profile than other claw-style couplings to fit in cramped spaces. They consist of a plug and a socket that connect with a quarter twist. Also known as Bowes couplings.

Twist-Claw Hose Couplings for Dry Abrasive Material

Use these fittings with sand, steel shot, and other abrasive material. Fittings have a unique claw-style head that connects to other abrasive-material hose fittings with a quarter twist.
