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.

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 D1784 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).

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.

High-Pressure Barbed Plastic Pipe Fittings for Water

Use these barbed pipe fittings in industrial plumbing, water processing, and water supply applications up to 200 psi. They meet NSF/ANSI Standard 61 for drinking water. Also known as insert fittings, they have a barbed end that slides into semi-flexible plastic pipe and secures with a clamp (sold separately). Since you don't have to wait for cement to dry, they're quicker to install than socket-connect fittings. Fittings are PVC, which has good strength and corrosion resistance. They meet ASTM D1784 specifications and testing requirements for material quality and ASTM D2609 specifications for barb dimensions.

Note: Barbed pipe fittings are measured by pipe size, which is not an actual measured size, but rather an industry designation.

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

Sealants cannot be sold to Colorado, Connecticut, District of Columbia, Delaware, Illinois, Indiana, Massachusetts, Maryland, Maine, Michigan, New Hampshire, New Jersey, Northern Virginia, New York, Ohio, Pennsylvania, Rhode Island, or Utah due to local VOC (Volatile Organic Compounds) regulations.

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.

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 a wide variety of acids, solvents, and other harsh substances. Apply a non-hardening, plastic-compatible sealant to the male threads to prevent leaks. Tape or sealants with PTFE are not recommended for plastic-to-plastic threaded connections. When making a threaded connection be careful not to overtighten the threads. To prevent cracks and leaks, finger tighten the fitting, then wrench-tighten one to two turns.

Schedule 80 fittings have thicker, stronger walls than Schedule 40 fittings for heavy duty, industrial chemical processing applications.

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