Not only do these PFA fittings have the chemical resistance to handle acid and salt water, they also have better crack resistance than other plastic pipe fittings for chemicals. Also known as Schedule 80 fittings, they have thick, strong walls to handle heavy duty chemical processing applications. Fittings have a super-smooth interior for unrestricted flow. They are commonly used in high-purity chemical flow processes, such as semiconductor and clean room applications, because the material won’t leach contaminates into the line.

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.
