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.

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

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

Typically used with standard-wall and low-pressure iron and steel unthreaded pipe fittings. Also known as Schedule 40.

Typically used with extreme-pressure iron and steel unthreaded pipe fittings. Pipe is also known as Schedule XXH .

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.

Compatible with ARO-shape plugs and sockets.

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

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.

Couplings are metal, which has better durability than plastic cam-and-groove hose couplings. Also known as dry disconnects and double shut-off couplings, they have a shut-off valve in the plug and the socket for minimal fluid loss when disconnecting your hose line.

Quickly connect and disconnect hose lines used with a variety of chemicals, from adhesives to isopropyl alcohol and ink. Any part of these couplings that contacts fluid is made from 316 stainless steel, C-276 Hastelloy, PTFE, or fluoroelastomer to withstand the chemicals in your line.

Connect your hose to a cam-and-groove vapor recovery valve.

Built with ball bearings, these fittings continuously swivel 360° before and after installation to prevent your hose from twisting, kinking, and failing. They’re made of 316 stainless steel, so they won’t corrode from a wide variety of chemicals, as well as fuels, gasoline, and oil.

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.

Fittings have sharp barbs that grip push-on hose with no clamps or ferrules required. The more you pull on the fittings, the tighter the hose will grip. Use in low-pressure hydraulic applications up to 350 psi.

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

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 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 A-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.

Add quick connection points for mechanical gauges and other diagnostic equipment to your line. These couplings are also known as test ports and diagnostic 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.

Use these kink absorbers to ensure maximum water flow and extend the life of your garden hose. They connect between the hose and faucet to eliminate sharp hose bends that can cause kinking and hose damage.

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.

Use these barbed fittings in low-pressure steam applications up to 150 psi. Slide the barbed end into hose and secure with a clamp.

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.

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.

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°.

The threads on the tube end of these fittings are Class 3A or 3B and adhere to tighter tolerances than other 37° flared fittings.

Use these fittings at pressures up to 9,700 psi. Also known as instrumentation fittings, they are made to tight tolerances for use in high-precision applications. They are compatible with Swagelok®, Let-Lok, and Parker A-Lok fittings.

Polished to at least a 15 Ra finish on the inside, these fittings have an ultra-smooth interior surface that helps prevent contamination. They are also known as ultra-high-purity fittings.
