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.

High-Temperature Push-to-Connect
Tube Fittings for Air and Water

Withstanding temperatures up to 300° F, these fittings have the highest temperature rating of all our push-to-connect tube fittings for air and water.

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.

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.

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.

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.

Thick-Wall Plastic Pipe Fittings for Water

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.

CPVC Pipe Fittings for Hot Water

Connect to CPVC pipe for use in high-temperature plumbing and water supply applications up to 200° F.

UV-Resistant Standard-Wall PVC Pipe Fittings for Water

Connect these fittings to UV-resistant PVC pipe. Designed for outdoor use, they contain an additive that protects against the damaging effects of ultraviolet light. Fittings are typically used in low-pressure residential and commercial plumbing and water supply applications up to 300 psi.

Drain, Waste, and Vent ABS Pipe Fittings for Chemicals

These fittings are an economical option for chemical waste systems. Fittings are ABS plastic, which has excellent strength and impact resistance and good chemical resistance.

Leveling Mount Inserts for Tubular Legs

High-Capacity Leveling Mount Inserts for Tubular Legs

Rated for high load capacity, use these inserts to connect threaded leveling mounts to heavy equipment.

Metric High-Capacity Leveling
Mount Inserts for Tubular Legs

Rated for high load capacity, use these metric inserts to connect threaded leveling mounts to heavy equipment.

Leveling Mount Inserts for Tubular Legs

Slip these inserts into tubular legs to quickly add threads for attaching leveling mounts. They’re often used in the legs of light equipment and furniture.

Leveling Mounts for Tubular Legs

Insert these adjustable mounts into tube ends to level your equipment in a single step.
