About Pipe and Fittings

Measure your pipe and fittings to identify their pipe size, thread size, schedule, and thread type. Then, find compatible components.

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.

To prevent leaks in threaded connections, apply a sealant to the male threads. Threaded connections can be taken apart as needed for maintenance and repair. For metal threads, use PTFE tape. For plastic threads, apply a non-hardening, plastic-compatible sealant. Tape or sealants with PTFE are not recommended for plastic-to-plastic 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.

Through-Wall Straight Connectors for Tanks with Gasket

NPT Female

Through-wall fittings are also known as bulkhead couplings; they mount through your wall or tank to create an inlet or outlet. When installing, the gasket should be on the inside of the wall.

Fittings for tanks create an inlet or outlet connection on the surface of any tank, pressure vessel, or drum.

Flame-Retardant Drain, Waste, and Vent CPVC Pipe Fittings for Chemicals

Made of CPVC, these fittings have better chemical resistance than ABS plastic gravity-flow fittings and can stand up to highly-corrosive acids and other harsh substances. They meet NSF/ANSI 14 requirements for use in corrosive waste gravity-flow systems. Fittings are comparable to Corzan. They meet UL 94 V-0 for flame retardance and ASTM F2618 specifications and testing requirements for material quality. They are IAPMO certified to comply with the International Association for Plumbing and Mechanical Officials product performance standards and the Uniform Plumbing Code (UPC) for installation and repair of plumbing systems.

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