Flame-Retardant PVDF Pipe Fittings for Chemicals
- For Use With: Chlorine, Salt Water, Solvents
- Temperature Range: 40° to 280° F
- Specifications Met: ASTM D3222, UL 94V0
- Pipe Nipples and Pipe: Use Schedule 80 PVDF Plastic
- Flanges: Use Class 150 PVDF Plastic
These fittings meet UL 94V0 for flame retardance, so they delay the spread of flames to valuable equipment. They are made of PVDF (polyvinylidene fluoride), which is comparable to Kynar, and has the chemical resistance to stand up to solvents and other harsh substances. Also known as Schedule 80 fittings, they have thick walls for heavy duty chemical processing applications. When connecting to pipe, 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. Fittings meet ASTM D3222 specifications and testing requirements for material quality.
Warning: Never use plastic pipe fittings and pipe with compressed air or gas.
