UV-Resistant Polypropylene Pipe Fittings for Chemicals

Made of polypropylene, these fittings won’t deteriorate when exposed to the damaging effects of ultraviolet light and are suitable to use outdoors. They have the chemical resistance to withstand a wide variety of acids, solvents, and other harsh substances.

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.

Through-Wall Straight Connectors for Tanks with Gasket

NPT Female

Through-wall fittings are also known as bulkhead couplings; they mount through your wall or tank to create an inlet or outlet. When installing, the gasket should be on the inside of the wall.

Fittings for tanks create an inlet or outlet connection on the surface of any tank, pressure vessel, or drum.

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.

Low-Pressure Stainless Steel Clamp-On Pipe Fittings

Create liquid-tight connections with these connectors. They join rigid pipe of the same or different materials.

Straight Connectors with FEP Sleeve

Clamp On

With an FEP sleeve and PTFE sealing tape, these connectors withstand chemicals better than rubber connectors. Use them for joining low-pressure chemical waste drainpipe and fittings or transitioning between different chemical piping. The connectors are 316 stainless steel for excellent corrosion resistance. They stand up to wet environments, just like 304 stainless steel, but unlike 304 stainless steel, they will not corrode from salt water, chlorine solutions, and chemicals.

To install, chamfer and deburr both ends of the pipe you need to join. Mark each pipe adjacent to the connector bands and apply 10 layers of the PTFE tape directly over each line. Doing this creates a seal between the sleeve and the pipe for extra leak protection. Then, center the FEP sleeve over the tape and use a heat gun to shrink the sleeve onto the pipe. Next, center the connector and tighten the clamps to 60 inch-lbs. to form a tight seal. Finally, test for leaks.

316 Stainless Steel—Fittings are the most corrosion resistant. They stand up to wet environments, just like 304 stainless steel fittings, but unlike 304 stainless steel, they will not corrode from salt water, chlorine solutions, and chemicals.
