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.

Metal Barbed Hose Fittings for Air and Water

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

Easy-Fit Barbed Hose Fittings for Air and Water

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.

Threaded Swivel Hose Fittings for Air

Connect these fittings to air tools for pneumatic applications.

Easy-Fit Barbed Hose Fittings for Chemicals

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.

Ultra-High-Vacuum Hose with Flanges

Often found in semiconductor manufacturing and other demanding industrial applications, this hose handles nearly perfect vacuum.

Tube Fittings for Plastic and Rubber Tubing

Barbed Tube Fittings for Drinking Water

Connect these fittings to tubing with a ring and a crimping tool (both sold separately). Safe to use with drinking water, these fittings meet the strict standards of NSF/ANSI 61.

Socket-Connect Fittings for
Plastic Tubing—Drinking Water

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

Stainless Steel Barbed Tube
Fittings for Food and Beverage

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

Barbed Fittings for Plastic and
Rubber Tubing—Gasoline

Fittings have a barb that grips onto tubing. Use in applications up to 150 psi.

Tube Fittings for Metal Tubing

Precision AN 37° Flared Fittings
for Stainless Steel Tubing

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

Vibration-Resistant Precision AN 37°
Flared Fittings for Stainless Steel Tubing

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

Ultra-High-Vacuum Flanges and
Fittings for Stainless Steel Tubing

Create access points in ultra-high-vacuum lines or chambers by bolting two same-size flanges together with a copper gasket between them. The flanges’ sharp edges dig into the copper gasket and form an extremely tight seal, which means they handle higher vacuum pressures than other high-vacuum fittings with rubber gaskets.

Solder-Connect Fittings for Copper Tubing

Solder these fittings to tubing for a permanent, leak-tight connection. They are also known as sweat fittings.

Yor-Lok Fittings for Steel Tubing

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

Acid-Resistant Yor-Lok
Fittings for Nickel Alloy Tubing

These Monel fittings have the corrosion resistance to handle hydrofluoric and sulfuric acid. Also known as instrumentation fittings, they include a nut with two sleeves.

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.

High-Pressure Barbed Plastic
Pipe Fittings for Water

Use for pressures up to 200 psi. Also known as insert fittings, these slide into semi-flexible plastic pipe and secure with a clamp.

Low-Pressure Barbed Plastic Pipe Fittings for Water

Use for pressures up to 60 psi. Also known as insert fittings, these slide into semi-flexible plastic pipe and secure with a clamp.

Standard-Wall Plastic Pipe Fittings for Water

Connect these fittings to Schedule 40 plastic pipe—they are the industry standard for residential and commercial low-pressure plumbing and water supply applications. They are plastic for good corrosion resistance.

High-Temperature PTFE Pipe Fittings for Chemicals

Extreme temperatures are no problem for these fittings—they’re made of PTFE, so they can withstand a wider temperature range than any of our other plastic pipe fittings for chemicals. They are commonly used in high-purity chemical flow processes, such as semiconductor and clean room applications.

High-Purity PVDF Pipe Fittings
for Corrosive Chemicals

Made of PVDF that’s finished to a 12 Ra smoothness, these fittings handle some of the harshest chemicals without leaching contaminants into your line. Comparable to Kynar, they handle most organic solvents that would dissolve CPVC, and chlorine or nitric acid that would weaken polypropylene.

Aluminum Quick-Connect Pipe for Compressed Air

Build a compressed air system in half the time it would take to build a copper or steel system.
