Keep a variety of lengths of pipe and pipe nipples on hand for areas where corrosion is a concern.

Typically used with low-pressure stainless steel threaded pipe fittings.

Typically used with medium- to high-pressure stainless steel threaded pipe fittings.

These fittings are made to tighter tolerances than other stainless steel pipe fittings. They are also known as instrumentation fittings.

When space is at a premium choose these compact fittings.

Typically used with thin-wall stainless steel unthreaded pipe fittings.

Typically used with thick-wall and high-pressure stainless steel unthreaded pipe fittings.

For extra leak protection in low-pressure lines, the threads of this Schedule 40 pipe have sealant already applied.

Pipe has clockwise (right-hand) threads on one end and counterclockwise (left-hand) threads on the other end. When you use a wrench to turn, connections on both ends tighten at the same time.

A plastic sleeve prevents destructive corrosion when connecting different metals.

Assortments contain threaded pipe in various lengths.

Typically used with medium-pressure galvanized iron and steel threaded pipe fittings. Also known as Schedule 80.

Made to tighter tolerances than other steel pipe fittings, these are also known as instrumentation fittings.

Typically used with high-pressure iron and steel threaded pipe fittings. Also known as Schedule 160.

Crimp these fittings onto steel pipe to form a tightly sealed connection that’s faster than threading or welding and doesn’t require heat.

Socket-connect fittings are easier to weld than butt-weld fittings because the fitting doesn't need to align perfectly to the pipe. Slide the pipe into the socket and weld.

Low-profile barbs and a longer first barb allow for a smoother, easier installation than other barbed fittings. Slide the barbed end into hose and secure with a clamp.

The female connector screws directly onto the hose without the need for a separate adapter. When assembled, the fitting compresses against the hose, forming a strong seal. Also known as reusable fittings, they can be unscrewed from the hose end and used on a new hose.

Kits contain Industrial quick-disconnect plugs in four coupling sizes so you can determine the size of your couplings without needing to measure.

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

Compatible with Lincoln-shape plugs and sockets.

Compatible with Schrader-shape plugs and sockets.

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

Plugs and sockets are color coded by shape so you can't mix hose lines. Only plugs and sockets of the same color will fit together.

Couplings have an identical claw-style head that connects to another twist-claw hose coupling with a quarter twist.

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.

These nuts attach to high-pressure nipples for compressed gas so you can connect your tank to the inlet of a pressure regulator.

Also known as live swivels, these fittings swivel continuously 360° before and after installation. This not only makes installation easier, but also eliminates the twisting and kinking that can cause hose failure. 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.

Create or repair D.O.T. hose assemblies in the field with just a wrench and a vise, no crimper required.

Crimp these fittings onto hydraulic hose for a permanent, leak-tight connection. Since they crimp on, they handle higher pressure than screw-on fittings.

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.

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.

Use these couplings at pressures up to 6,500 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 Snap-Tite H-Shape plugs and sockets.

Ideal for lines with rapid changes in pressure and flow, these couplings have threads that lock them together. They connect more securely than push-to-connect couplings, whose bearings wear out in high-impulse conditions.

Each of these metal fittings is double bagged to prevent contamination in areas that require a high level of cleanliness.

Couplings are metal, which has better durability than plastic 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.

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.

Also known as dry disconnects and double shut-off couplings, these couplings make connecting and disconnecting your line quick and virtually spill-free. Built to stand up to petroleum products, such as diesel fuel and gasoline, their body and gasket are made from materials that won’t corrode from oil.

Minimize chemical and petroleum spills during accidental disconnects, such as a driver pulling away during loading. These couplings have a shut-off valve on each half to stop flow when they’re separated.

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.

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.

Also known as ground-joint couplings and boss couplings, these fittings are designed for high-pressure steam applications up to 600 psi. Insert the barbed end of the fitting into hose, then position the interlocking clamp over the hose and bolt into place. The clamp firmly grips your hose as it locks into the ring of the barbed end, creating a leak-tight seal.

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

A PTFE seal on the tube end of these fittings allows for an extra-strong connection in high-vibration applications.

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

These fittings have two sleeves for extra gripping power. They bite into steel tubing as you tighten the nut to form a strong seal.

Use these luer lock couplings to quickly connect low-pressure air and water lines. Made of stainless steel, they’re more durable than plastic couplings.

Made of stainless steel, these fittings are more durable than plastic barbed tube fittings for food and beverage.

Keep thin grease from leaking out—the check valve on these fittings has a Buna-N seat that creates a tighter seal than check valves on other grease fittings.

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

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

To fit securely in unthreaded holes, these fittings cut threads as they’re installed.

Ensure a secure fit in unthreaded holes—these fittings cut threads as they’re installed. Use these fittings in tight spaces where protruding fittings won't work.

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

Flush out clogged grease in your fitting. Tapping these tools with a hammer forces light oil through your fitting and removes contamination from bearings, joints, and other parts.

Remove worn fittings and repair threaded holes.
