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.

Compact Extreme-Pressure
Steel Threaded Pipe Fittings

These fittings are strong enough to handle extreme pressures, yet small enough to fit into cramped spaces.

Low-Pressure Iron and Steel Threaded Pipe Fittings

Use these fittings for low-pressure applications in noncorrosive environments.

Low-Pressure Stainless Steel Threaded Pipe Fittings

Use these corrosion-resistant fittings in a low-pressure pipe line.

High-Pressure Stainless Steel Threaded Pipe Fittings

Use these heavy duty, corrosion-resistant fittings in high-pressure flow applications.

Extreme-Pressure Stainless
Steel Threaded Pipe Fittings

Use these fittings in extreme-pressure conditions up to 15,000 psi.

Miniature Medium-Pressure Stainless
Steel Threaded Pipe Fittings

When space is at a premium choose these compact fittings.

High-Pressure Brass Threaded Pipe Fittings

These brass fittings have the strength to handle high-pressure applications.

High-Pressure Plated Brass Threaded Pipe Fittings

The plating on these brass fittings creates a shiny finish and provides extra protection in corrosive environments. Fittings have the strength to handle high-pressure applications.

Extreme-Pressure Brass Threaded Pipe Fittings

Extreme pressures are no problem for these heavy-duty brass fittings.

Medium-Pressure Plated Brass Threaded Pipe Fittings

Plated with nickel, these brass fittings resist rust better than steel and unfinished brass fittings. Select them when you need more strength in corrosive environments to handle higher pressures than our low-pressure fittings.

Low-Pressure Aluminum Threaded Pipe Fittings

In addition to being lightweight, these aluminum fittings offer good corrosion resistance. Use them in low-pressure flow applications.

Plastic Pipe Fittings for Oil

Made of corrosion-resistant plastic, these fittings won’t deteriorate when used in oil applications. They have high strength and impact resistance.

Plastic Pipe Fittings for Gasoline

Use these plastic fittings to connect gasoline fuel lines to machines and equipment. They have excellent corrosion resistance as well as high strength and impact resistance.

30° Flared Fittings for Steel Tubing

Also known as JIS (Japanese Industrial Standard) fittings.

Hose 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.

Open-Flow Quick-Disconnect
Hose Couplings for Air and Water

Couplings allow for maximum flow because there's no shut-off valve in the plug or the socket. Compatible with Open-Flow-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.

ARO Quick-Disconnect Hose Couplings for Air

Compatible with ARO-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.

Metal Cam-and-Groove Hose Couplings for Water

Metal cam-and-groove couplings have better durability than plastic cam-and-groove couplings.

Plastic Cam-and-Groove Hose Couplings for Water

Made of polypropylene, these cam-and-groove couplings are lighter in weight than metal cam-and-groove hose couplings.

Plastic Cam-and-Groove Hose
Couplings for Chemicals and Petroleum

Couplings are plastic, which is lighter in weight than metal cam-and-groove hose couplings. They consist of a plug and a socket that connect and disconnect quickly. Use them if you need frequent access to a line. To connect, insert the plug into the socket and push the levers down.

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.

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.

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.

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.

Threaded Hose Fittings for Hydraulic Fluid

Fittings are threaded on both ends so you can connect them directly to a threaded hose or to pumps, cylinders, and other equipment in your hydraulic system. Use in high-pressure applications up to 6,000 psi

Cam-and-Groove Hose Couplings
for Food and Beverage

Couplings are made of FDA listed materials, 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. Use them if you need frequent access to a line. To connect, insert the plug into the socket and push the levers down.

Sights

Shatter-Resistant Sights

The window and body are made from a single piece of plastic, making these sights more shatter resistant than sights with a glass window.

Sights

These sights have a glass window.

Grease Fittings

Grease Fitting Assortments

Keep a variety of grease fitting shapes, styles, and sizes on hand.

Flush-Style Grease Fittings

The nipple doesn't stick out, so these fittings fit in tight spaces and won't be damaged if something knocks into them.

Button-Head Grease Fittings

Often used on earth movers, mining equipment, and other heavy machinery, these fittings have a T-shaped top that holds the dispensing tip in place so it won't pop off when adding grease.

Grease Fitting Adapters

When the size or thread type of a fitting doesn't match an existing opening, use these adapters to make the connection.
