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.

- 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.

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.
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.
