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. 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 connect, finger tighten the fitting, then wrench-tighten one to two turns.

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