Twist-Claw Hose Couplings for Air and Water
Also known as Chicago and universal couplings, these have an identical claw-style head that allows you to connect to another Chicago twist-claw hose coupling, regardless of the pipe size or barbed hose ID. To connect, push two couplings together with a quarter twist. Couplings have a safety clip and lanyard to prevent accidental disconnection.
Couplings with a barbed end insert into rubber hose and secure with a clamp.
Wye couplings are also known as three-way hose couplings. Use them to connect one inlet to two outlets.
Iron couplings are stronger and more durable than other metal couplings. Use in noncorrosive environments. Warning: There is no valve in these couplings. Stop the flow of air and water before you disconnect the line.

Spring-Lock Twist-Claw Hose Couplings for Air and Water
Prevent accidental disconnection with these couplings—they have a spring-loaded locking sleeve that automatically locks into place when you connect the coupling. Also known as Chicago and universal couplings, they have an identical claw-style head that allows you to connect to any other spring-lock twist-claw hose coupling. To connect, push two couplings together with a quarter twist. To disconnect, slide the locking sleeves back and twist the couplings apart. Couplings are iron, which is strong and durable. Use in noncorrosive environments.
Couplings with a barbed end insert into rubber hose and secure with a clamp.
Warning: There is no valve in these couplings. Stop the flow of air and water before you disconnect the line.

Large Twist-Claw Hose Couplings for Air and Water
Also known as universal couplings, these have identical claw-style heads and connect by being pushed together with a quarter twist. Couplings include a safety clip to prevent accidental disconnection. They are made of iron, which is strong and durable, and have a black painted finish for fair corrosion resistance. Use in noncorrosive environments.
Warning: There is no valve in these couplings. Stop the flow of air and water before you disconnect the line.

Extra-Large Twist-Claw Hose Couplings for Air and Water
Also known as universal couplings, these have an identical claw-style head that allows you to connect to any other extra-large twist-claw hose coupling. To connect, push two couplings together with a quarter twist. Couplings include a safety clip to prevent accidental disconnection. They are made of iron, which is strong and durable, and have a black painted finish for fair corrosion resistance. Use in noncorrosive environments.
Warning: There is no valve in these couplings. Stop the flow of air and water before you disconnect the line.

Interlocking-Clamp Hose Fittings for Steam
Also known as ground-joint couplings and boss couplings, these fittings are designed for high-pressure steam heating, humidification, and washdown applications. Insert the barbed end of the fitting into rubber hose, then position the interlocking clamp over the hose and bolt into place with a torque wrench. The clamp firmly grips the hose as it locks into the ring of the barbed end, creating a leak tight seal. The interlocking clamps are not reusable. Fittings are strong and durable with fair corrosion resistance.
Fittings with a female threaded end have a hex bushing (also known as a female spud) that connects to a male interlocking-clamp hose fitting. Replace the hex bushing with a hex nipple (sold separately) to connect two female fittings; the hex nipples are also known as double spuds.
Warning: There is no valve in these couplings. Stop the flow of steam before you disconnect the hose line.

Air Hose with Twist-Claw Fittings
- Temperature Range: -40° to 200° F
- Material: EPDM Rubber
- Color: Black or Red
Hose is made of EPDM rubber, which is the most common material for air applications. The fittings are also known as universal hose couplings and are interchangeable with each other regardless of hose size.
For any combination of hose length and fittings not listed in the table, please select 5138K999. Specify hose color (red or black) and length, and fitting type, material, and size on both ends.
