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.

Standard-Wall Butt-Weld Stainless Steel Unthreaded Pipe Fittings

Also known as Schedule 40 fittings, these have thicker walls than our thin-wall stainless steel unthreaded butt-weld fittings. They have beveled ends that, when flush to pipe, create a trough for a strong weld that permits maximum flow.

304 stainless steel fittings have very good corrosion resistance. 316 stainless steel fittings have excellent corrosion resistance.

Thin-Wall Butt-Weld Stainless Steel Unthreaded Pipe Fittings

Also known as Schedule 10 fittings, these are thin and lightweight. They have beveled ends that, when flush to pipe, create a trough for a strong weld that permits maximum flow.

304 stainless steel fittings have very good corrosion resistance. 316 stainless steel fittings have excellent corrosion resistance.

Standard-Wall Butt-Weld Steel Unthreaded Pipe Fittings

Butt-weld fittings allow for a smooth connection that provides maximum flow. They have beveled ends that, when flush to pipe, create a trough for a strong, permanent weld. Fittings are also known as Schedule 40. They are for use in noncorrosive environments.

Thick-Wall Plastic Pipe Fittings for Water

Connect these fittings to Schedule 80 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. Fittings are plastic for good corrosion resistance. They meet ASTM specifications and testing requirements for material quality.

Fittings for drinking water meet NSF/ANSI Standard 61.

Attach socket-connect ends to unthreaded pipe or another socket-connect fitting with a PVC primer and cement (also known as solvent weld).

To prevent leaks in threaded connections, apply a sealant to the male threads. For plastic threads, apply a non-hardening, plastic-compatible sealant. Tape or sealants with PTFE are not recommended for plastic-to-plastic connections.

Note: For fittings that are not rated for pressure, you can use the pressure rating of the plastic pipe as a reference. Threaded fittings are limited to 50% of the rated pressure of the pipe.

Warning: Never use plastic pipe fittings and pipe with compressed air or gas.

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.

Fittings for drinking water meet NSF/ANSI Standard 61.

Attach socket-connect ends to unthreaded pipe or another socket-connect fitting with a PVC primer and cement (also known as solvent weld).

Fittings that meet ASTM D1784, ASTM D1785, and ASTM D4066 adhere to specifications and testing requirements for material quality.

Note: For fittings that are not rated for pressure, you can use the pressure rating of the plastic pipe as a reference. Threaded fittings are limited to 50% of the rated pressure of the pipe.

Warning: Never use plastic pipe fittings and pipe with compressed air or gas.

CPVC Pipe Fittings for Hot Water

Made of CPVC, these fittings can handle high temperatures up to 200° F. They have thick, strong walls to handle heavy duty industrial plumbing and water supply applications, such as water processing and waste water treatment. They also have good corrosion resistance. These fittings are comparable to Corzan. Some meet ASTM D1784 specifications and testing requirements for material quality.

Fittings for drinking water meet NSF/ANSI Standard 61.

Note: For fittings that are not rated for pressure, you can use the pressure rating of the plastic pipe as a reference. Threaded fittings are limited to 50% of the rated pressure of the pipe.

Warning: Never use plastic pipe fittings and pipe with compressed air or gas.
