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.

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.

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.

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.

Dust Caps and Plugs for International Standard ISO B
Quick-Disconnect Hose Couplings for Hydraulic Fluid

Use these dust caps and plugs to keep contaminants out of your hose line.

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.

Dust Caps and Plugs for International Standard
ISO Minimal-Spill Quick-Disconnect
Hose Couplings for Hydraulic Fluid

Use these dust caps and plugs to keep contaminants out of your hose line.

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

Dust Caps and Plugs for International Standard ISO A
Quick-Disconnect Hose Couplings for Hydraulic Fluid

Use these dust caps and plugs to keep contaminants out of your hose line.

Quick-Disconnect Hose Couplings for Steam

Couplings consist of a plug and a socket that connect quickly. Use them if you need frequent access to a line. They are designed for low-pressure steam applications up to 300 psi.

International Standard ISO B Quick-Disconnect
Hose Couplings for Food and Beverage

These couplings are compatible with International Standard ISO Series B-shape plugs and sockets. They are FDA compliant, so they’re suitable for food and beverage applications and won’t impart tastes or odors to the product. They consist of a plug and a socket that connect and disconnect quickly so you can frequently access your line. Use at pressures up to 220 psi.

Hydraulic Hose

Hydraulic Hose with Female Threaded Fittings

Hydraulic Hose with Male and Female Threaded Fittings

Transfer fluid between pumps, cylinders, and other parts of your hydraulic system with this hose that has attached fittings to save time and eliminate points of failure.

Hydraulic Hose with Quick-Disconnect
Socket and Female Threaded Fitting

Hydraulic Hose with Quick-Disconnect
Plug and Threaded Male Fitting

Hydraulic Hose with Quick-Disconnect Fittings

When you need access to your line, don’t waste time threading and unthreading your fittings. This hose has a quick-disconnect fitting on both ends.

Lightweight Hydraulic Hose
with Female Threaded Fittings

Push-to-Connect Tube Fittings for Air

Tube Fittings for Metal Tubing

37° Flared Fittings for Stainless Steel Tubing

Also known as JIC (Joint Industrial Council) fittings, these provide a tight metal-to-metal seal on stainless steel tubing that is flared to 37°.

Nuts for 37° Flared Fittings for Stainless Steel Tubing

Cleaned and Bagged 37° Flared
Fittings for Stainless Steel Tubing

Individually bagged to prevent contamination, these fittings are suitable for applications that require a high level of cleanliness.

Sleeves for 37° Flared Fittings
for Stainless Steel Tubing

Quick-Clamp High-Vacuum
Fittings for Stainless Steel Tubing

Also known as KF, QF, and NW fittings, these fittings are for high-vacuum applications, such as vacuum coating and heat treating, leak testing, and analyzing gases.

37° Flared Fittings for Copper Tubing

Also known as JIC (Joint Industrial Council) fittings, these connect to tubing that is flared to 37°. They can handle higher pressures than 45° flared fittings.
