Plastic Pipe Fittings for Oil
Made of corrosion-resistant plastic, these fittings won’t deteriorate when used in oil applications. They also have high strength and impact resistance. 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.
Warning: Never use plastic pipe fittings and pipe with compressed air or gas.
