Make lightweight connections without the hassle of matching the exact thread type—these fittings connect to NPT, NPTF, BSPP, BSPT, and other universal threads.

Made of nickel-plated brass, these tube fittings resist corrosion better than plain brass fittings. The male threaded ends connect to NPT, NPTF, BSPP, BSPT, and other universal threads, so you don’t have to bother matching exact thread types.

Often used in outdoor, damp, and washdown environments, these 316 stainless steel fittings will not corrode from water, salt, or chemicals. The male threaded ends mate with NPT, NPTF, BSPT, BSPP, and other universal threads, so you won’t have to worry about matching exact threads when you’re on the job.

These fittings won’t absorb moisture, so they’re good for water and high-humidity air applications.

Ball bearings allow these fittings to rotate 360°, even after they are tightened. They have a special seal that reduces friction to allow for continuous rotation.

An all-metal body and built-in tube support or dual seals allow these fittings to handle the highest pressure ratings of all our push-to-connect tube fittings.

Color-code fittings for easy identification. These aluminum fittings have good corrosion resistance, but are lighter in weight than brass.

Fittings have good corrosion resistance.

Aluminum fittings have good corrosion resistance, but are lighter in weight than brass.

A single sleeve (ferrule) compresses the tubing as you tighten the nut on these fittings, creating a strong seal. They are brass for good corrosion resistance.

Couplings can handle pressures up to 250 psi.

Use these nuts with brass compression fittings to create a seal on plastic tubing. They meet NSF/ANSI 61 for use with drinking water.

Fittings are 316 stainless steel, which has excellent chemical resistance and is more durable than plastic.

These quick-disconnect couplings mate with a sanitary stainless steel quick-clamp fitting for use in dairy lines.

Use these nuts and sleeves with compression fittings for food and beverage to create a seal on plastic tubing.

Connect these fittings to thick-wall plastic pipe—they have thicker, stronger walls than standard-wall fittings, so they can handle heavy duty industrial plumbing and water supply applications, such as water processing, waste water treatment, and irrigation. They can withstand pressures up to 900 psi.

Connect to thick-wall plastic pipe fittings for use in heavy duty industrial plumbing and water supply applications, such as water processing, waste water treatment, and irrigation. Pipe can handle pressures up to 900 psi.

Bolt two same-size flanges together with a gasket to create an access point within a line. They are also known as Pressure Class 150 flanges. Use in high-temperature plumbing and water supply applications up to 200° F.

Use in low-pressure applications up to 150 psi.

Snap these clamps around leaking pipe with only your hands. No tools required.

A great solution when space is at a premium, these manifolds are less than an inch in height, yet allow you to supply up to 12 lines from one distribution point.

Distribute air or fluid to multiple locations from a single supply source with these manifolds. They are also known as headers.

Mount these manifolds on the end of a hose line to distribute air, water, or hydraulic fluid to three locations from a single supply source.

Use these manifolds with molding equipment to circulate hot and cold water through your line. They have a red side for hot water and a blue side for cold water.

Use these junction blocks to organize and separate multiple lines in your system. They have threaded holes that allow air or fluid to flow straight through the block.

Metal hose fittings have better durability than plastic barbed hose fittings.

Compatible with ARO-shape plugs and sockets.

The industry standard for quick-disconnect couplings, these are also known as industrial interchange couplings. Compatible with Industrial-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 a spring-loaded locking sleeve that automatically locks into place to prevent accidental disconnection. The identical claw-style head connects to another spring-lock twist-claw hose coupling with a quarter twist.

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

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.

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.

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.

Couplings are compatible with quick-disconnect Plastic-shape plugs and sockets. They are designed 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 100 psi.

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.

A braided exterior protects this hose from abrasion and over-bending. Also known as bellows, the ribbed interior makes it flexible enough to connect high-vacuum components that aren't directly aligned.

More flexible than rigid stainless steel tubing, this hose allows you to link high-vacuum components that are misaligned. Also known as bellows. Equipped with a claw-clamp (ISO-K) fitting on each end, this hose connects to large components with fittings starting at trade number 63.

Attach push-on barbed fittings to this hose for use in low-pressure hydraulic applications. No clamps are needed to secure fittings to the hose; the more you pull on the fittings, the tighter the hose will grip.

Also known as vacuum isolation valves, these block flow so you can install and remove gauges from your system. They can also be used to add or vent gases in high-vacuum systems.
