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.

About Plastic

Color: White
Temperature Range: 45° to 180° F
Tensile Strength: 4,060-4,930 psi (Poor)
Impact Strength 0.9-1.9 ft.-lbs./in. (Poor)
Hardness: Rockwell R80-R90 (Hard)
For Use Outdoors: No

A good all-around choice, these rods have a hard, slippery surface that won’t bind or stick to cutting tools. They’re often used to make parts for laboratory equipment because they resist swelling when exposed to water. Polypropylene has good electrical insulation properties.

UV-Resistant Polypropylene Pipe for Chemicals

This polypropylene pipe resists the damaging effects of ultraviolet light, so it’s suitable for outdoor use. It has the chemical resistance to withstand a wide variety of acids, solvents, and other harsh substances. Pipe has thick, strong walls for heavy duty chemical processing applications. It meets ASTM D4101 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

For Use With: Acetic Acid (5%), Calcium Chloride, Deionized Water, Hydrochloric Acid (10%), Phosphoric Acid (85%), Salt Water, Sodium Chloride, Sodium Hydroxide, Sulfuric Acid, Water
Max. Temperature: 180° F
Specifications Met: ASME B1.20.1, ASTM D4101
Fittings: Use Schedule 80 Polypropylene Plastic
Flanges: Use Class 150 Polypropylene Plastic

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.

Pipe that meets ASME B1.20.1 adheres to quality specifications for thread dimensions.
