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.

For Use With: Chlorine, Salt Water, Solvents
Max. Temperature: 280° F
Specifications Met: ASTM D3222, UL 94 V-0
Fittings: Use Schedule 80 PVDF Plastic
Flanges: Use Class 150 PVDF Plastic

Pipe meets UL 94 V-0 for flame retardance, so it delays the spread of flames to valuable equipment. It is PVDF (polyvinylidene fluoride), which is comparable to Kynar, and has the chemical resistance to stand up to solvents and other harsh substances. Also known as Schedule 80 pipe, it has thick walls for heavy duty chemical processing applications. Pipe meets ASTM D3222 specifications and testing requirements for material quality.

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.

Threaded on Both Ends

To prevent leaks in threaded connections, apply a non-hardening, plastic-compatible sealant to the male threads. 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.

Flat Surface on Back

Raised Surface on Back

For Use With: Chlorine, Salt Water, Solvents
Temperature Range: 40° to 280° F
Specifications Met: ASTM D3222, UL 94 V-0
Pipe Nipples and Pipe: Use Schedule 80 PVDF Plastic
Fittings: Use Schedule 80 PVDF Plastic

Flanges meet UL 94 V-0 for flame retardance to delay the spread of flames to valuable equipment. They are made of PVDF (polyvinylidene fluoride), which is comparable to Kynar, and has the chemical resistance to stand up to solvents and other harsh substances. Also known as Pressure Class 150 flanges, they have thick, strong walls for heavy duty chemical processing applications. Bolt two same-size flanges together with a gasket (sold separately) to create an access point within a line. When connecting to pipe, 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 flange, then wrench-tighten one to two turns. Flanges meet ASTM D3222 specifications and testing requirements for material quality.

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