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.

Low-Pressure Iron and Steel Threaded Pipe Fittings

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

High-Pressure Iron and Steel Threaded Pipe Fittings

These fittings can stand up to high-pressure applications. Use them in noncorrosive environments.

Low-Pressure Stainless Steel Threaded Pipe Fittings

Use these corrosion-resistant fittings in a low-pressure pipe line.

Low-Pressure Aluminum Threaded Pipe Fittings

In addition to being lightweight, these aluminum fittings offer good corrosion resistance. Use them in low-pressure flow applications.

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.

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.

CPVC Pipe Fittings for Hot Water

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

UV-Resistant Polypropylene
Pipe Fittings for Chemicals

Made of polypropylene, these fittings won’t deteriorate when exposed to the damaging effects of ultraviolet light and are suitable to use outdoors. They have the chemical resistance to withstand acids, solvents, and other harsh substances.

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.

Plastic Pipe Fittings for Oil

Made of corrosion-resistant plastic, these fittings won’t deteriorate when used in oil applications. They have high strength and impact resistance.

Spin-Weld Through-Wall Plastic Tank Fittings

Create a leak-free, durable connection in plastic tanks, walls, or panels without gaskets or sealants.

Compressed Gas Hose Fittings

Threaded Hose-to-Propane-Tank
Adapters for Compressed Gas

These CGA adapters have a male threaded end that connects to a propane tank and a male threaded end that connects to welding hose.

High-Pressure Nipples for Compressed Gas

Commonly used in high-pressure welding applications, these nipples connect your tank to the inlet of a pressure regulator. One side has a threaded pipe end and the other side has a rounded end that sits inside a threaded nut to make a threaded connection.

Nuts for High-Pressure Nipples for Compressed Gas

These nuts attach to high-pressure nipples for compressed gas so you can connect your tank to the inlet of a pressure regulator.

High-Pressure Threaded
Fittings for Compressed Gas

Designed to handle high-pressure welding applications, these CGA fittings are commonly used to connect pressure regulators to compressed gas tanks or cylinders.

High-Polish Metal Quick-Clamp Sanitary Tube Fittings

High-Polish Metal Quick-Clamp
Sanitary Tube Fittings

The smooth finish inside these stainless steel quick-clamp fittings makes it easy to remove product residue.

Breather Vents

Protect against excess vacuum and pressure in cylinders, gear boxes, enclosures, manifolds, and tanks.

Weather-Resistant Breather Vents

Shield outdoor pipe and tank openings from the environment. Also known as vent caps, these breather vents have screens to allow air flow while blocking debris.

Lockable Breather Vents with Cap

Secure access to vented openings in pipe and tanks—the cap can be locked to prevent tampering.

Breather Vents with Cap

Add a filling port to your hydraulic tank while protecting against excess pressure and vacuum.
