About Pipe and Fittings

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

CPVC Pipe Nipples and Pipe for Chemicals

Made of CPVC, this pipe withstands salt solutions, acids, and other harsh substances. Also known as Schedule 80 pipe, it has thick, strong walls for use in heavy duty industrial plumbing and water supply applications, such as water processing and wastewater treatment. It’s comparable to Corzan.

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.

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

Pipe—Fully Threaded

Fully threaded pipe is also known as a close nipple; it is threaded on each end to the center.

CPVC Pipe Fittings for Chemicals

Made of CPVC, these fittings withstand salt solutions, acids, and other harsh substances. They have thick, strong walls to handle heavy duty industrial plumbing and water supply applications, such as water processing and wastewater treatment. These fittings are comparable to Corzan. Some meet ASTM D1784 specifications and testing requirements for material quality.

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

Straight Adapters

Cement Socket

Male × NPT Male

Cement-Socket Fitting Connection—Attach socket-connect ends to unthreaded pipe or another socket-connect fitting with a CPVC primer and cement (also known as solvent weld).

80 Pipe Schedule—Schedule 80 fittings have thick, strong walls for heavy duty, industrial applications.

NSF/ANSI 61—To adhere to safety standards for drinking water systems, use pipe that meets NSF/ANSI 61.
