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.

Vacuum Hose Reducers and Connectors

Connect vacuum hose and fittings.

Wet/Dry Vacuum Hose Reducers

These reducers work with any vacuum hose with the same diameter.

Design-Your-Own Dust Collector Duct System

Use these components to put together a duct system to collect sawdust, chips, shavings, and granular material from woodworking operations.

Tube Fittings for Metal Tubing

Butt-Weld Fittings for Stainless Steel Tubing

Butt-weld fittings allow for a smooth, flush connection that provides maximum flow.

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.

Yor-Lok Fittings for Stainless Steel Tubing

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.

Vacuum Fittings for Steel Tubing

Use these fittings in an air vacuum system to avoid the hassle of brazing and welding. Insert two fittings into a clamp and tighten to form a secure seal in steel tubing.

Tube Fittings for Plastic and Rubber Tubing

Plastic Push-to-Connect Tube Fittings for Chemicals

Also known as instant fittings, these chemical-resistant plastic fittings connect to tubing with a push. An internal gripping ring holds the tubing tight.

Stainless Steel Push-to-Connect
Tube Fittings for Chemicals

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

Push-to-Connect Fittings for
Plastic Tubing—High-Purity

Also known as instant fittings, they connect to tubing with a push, and an internal gripping ring and O-ring hold the tubing tight. Use in applications up to 140 psi.

Screw-On Nut Barbed Tube Fittings for Air

You don't need a clamp to secure these fittings to tubing. They have a nut on the barbed end that tightens to hold the tubing in place.

Push-to-Connect Tube
Fittings for Hot Drinking Water

Fittings can withstand temperatures up to 200° F.

Universal-Thread Push-to-Connect
Tube Fittings for Air and Water

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

Moisture-Resistant Push-to-Connect
Tube Fittings for Air and Water

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

Nickel-Plated Brass Push-to-Connect
Tube Fittings for Air

Made of nickel-plated brass, these fittings have better corrosion resistance than unplated brass fittings.

Push-to-Connect Tube Fittings for Air

Choose-a-Color Aluminum Low-Pressure
Barbed Tube Fittings for Air and Water

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

Nickel-Plated Brass Low-Pressure
Barbed Tube Fittings for Air and Water

The nickel plating on these fittings provides better corrosion resistance than unplated brass fittings.

Stainless Steel High-Pressure Barbed
Tube Fittings for Air and Water

Made of stainless steel, these fittings have better corrosion resistance than brass fittings.

Aluminum Low-Pressure Barbed
Tube Fittings for Air and Water

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

Brass Low-Pressure Barbed
Tube Fittings for Air and Water

Made of brass, these fittings resist corrosion from water and are more durable than plastic and aluminum fittings.

Hose Fittings

Metal Barbed Hose Fittings
for Chemicals and Petroleum

Made of stainless steel, these hose fittings are more durable than plastic barbed hose fittings and have excellent corrosion and chemical resistance. Slide the barbed end into hose and secure with a clamp.

Metal Barbed Hose Fittings for Air and Water

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

Pipe and Pipe Fittings

Right-Angle Flow Rectangular Manifolds

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

Cleaned-and-Bagged Right-Angle
Flow Rectangular Manifolds

Designed for ultra-clean environments, these manifolds are cleaned, dried, and vacuum sealed in plastic to prevent dirt and moisture from contaminating the inside. Use them to distribute air or fluid to multiple locations from a single supply source. Also known as headers.

Dual-Section Right-Angle
Flow Rectangular Manifolds

These manifolds have two separate sections inside, so you can run two different substances through them without worrying about them intermixing. Also known as headers.

Low-Profile Square Manifolds

With outlets on the side instead of on top, these manifolds have a lower profile than rectangular manifolds and fit well in cramped spaces. Use them to distribute air or fluid to three locations from a single supply source.

Color-Coded Irregular Hex Manifolds

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.

Round Manifolds for Hose Lines

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.

Low-Profile Hex Manifolds

When you’re short on vertical space, these manifolds are a good fit—they have outlets on the side instead of on top, so they have a lower profile than rectangular manifolds. Use them to distribute air or fluid to five locations from a single supply source.

Miniature Hex Manifolds

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.

Thick-Wall Plastic Pipe Fittings for Water

Connect these fittings to Schedule 80 pipe. With thicker, stronger walls than standard-wall fittings, they can handle heavy duty supply applications, such as water processing, wastewater treatment, and irrigation.

CPVC Pipe Fittings for Hot Water

Connect to CPVC pipe for use in high-temperature plumbing and water supply applications.

High-Pressure Stainless
Steel Threaded Pipe Fittings

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

Low-Pressure Iron and Steel Threaded Pipe Fittings

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