How to Identify and Measure Fittings

Pipe size is an industry designation, not the actual size. View information about how to measure threaded and unthreaded pipe and pipe fittings.

Plastic Quick-Disconnect Hose
Couplings for Air and Water

Made of acetal, these couplings are lighter in weight than metal quick-disconnect couplings. Compatible with Plastic-shape plugs and sockets.

Universal Quick-Disconnect Hose Sockets for Air

Sockets accommodate five common plug shapes: Industrial, ARO, Lincoln, Tru-Flate, and European.

Industrial Quick-Disconnect Hose Couplings for Air

The industry standard for quick-disconnect couplings, these are also known as industrial interchange couplings. Compatible with Industrial-shape plugs and sockets.

Tru-Flate Quick-Disconnect Hose Couplings for Air

Also known as automotive couplings. Compatible with Tru-Flate-shape plugs and sockets.

Lincoln Quick-Disconnect Hose Couplings for Air

Compatible with Lincoln-shape plugs and sockets.

ARO Quick-Disconnect Hose Couplings for Air

Compatible with ARO-shape plugs and sockets.

Compact Quick-Disconnect Hose Couplings for Air

A slim body allows these couplings to fit into tight spaces. Compatible with Compact-shape plugs and sockets.

Japanese Quick-Disconnect Hose Couplings for Air

Compatible with Japanese-shape plugs and sockets.

European Quick-Disconnect Hose Couplings for Air

With an unobstructed air path, these couplings have better airflow than other coupling shapes of the same size. Compatible with European-shape plugs and sockets.

International Standard ISO Minimal-Spill
Quick-Disconnect Hose Couplings for Chemicals

To minimize fluid loss when connecting and disconnecting your line, these couplings have flat faces for a close fit and shut-off valves to stop the flow—they meet ISO 16028, which is an international standard for hose couplings.

Quick-Disconnect Garden Hose Couplings

Couplings consist of a plug and a socket that connect more quickly than threaded garden hose couplings. To connect, push the plug into the socket. The compact design makes these couplings sleeker and easier to handle than cam-and-groove garden hose couplings.

High-Pressure Thread-Lock Quick-Disconnect
Hose Couplings for Hydraulic Fluid

Use these couplings at pressures up to 10,000 psi. The plug and socket thread together to form a stronger connection than other quick-disconnect couplings. They are compatible with High-Pressure Thread-Lock-shape plugs and sockets.

International Standard ISO Minimal-Spill
Quick-Disconnect Hose Couplings for Hydraulic Fluid

Use these couplings at pressures up to 7,200 psi. Also known as flush-face couplings, the plugs and sockets have a flat face, which allows them to mate close together, reducing fluid loss when connecting and disconnecting the line. They are compatible with International Standard ISO Minimal-Spill-shape plugs and sockets.

International Standard ISO B Quick-Disconnect
Hose Couplings for Hydraulic Fluid

Use these couplings at pressures up to 5,000 psi. They consist of a plug and socket that connect and disconnect quickly. Use them if you need frequent access to a line. They are compatible with International Standard ISO B-shape plugs and sockets.

Pioneer Quick-Disconnect Hose
Couplings for Hydraulic Fluid

Use these couplings at pressures up to 3,000 psi. They consist of a plug and socket that connect and disconnect quickly. Use them if you need frequent access to a line. They are compatible with Pioneer-shape plugs and sockets.

Natural and LP Gas Hose Fittings

Use these couplings when you need frequent access to a gas line. A complete coupling consists of a plug and a socket that connect and disconnect quickly.

Quick-Disconnect Hose Couplings for Coolant

Couplings consist of a plug and a socket that connect and disconnect quickly. Use them if you need frequent access to a line. They are designed for coolant applications up to 200 psi. Also known as coolant-line mold couplings.
