Connect these fittings to thick-wall plastic pipe—they have thicker, stronger walls than standard-wall fittings, so they can handle heavy duty industrial plumbing and water supply applications, such as water processing, waste water treatment, and irrigation. They can withstand pressures up to 900 psi.

Connect these fittings to UV-resistant PVC pipe. Designed for outdoor use, they contain an additive that protects against the damaging effects of ultraviolet light. Fittings are typically used in low-pressure residential and commercial plumbing and water supply applications up to 300 psi.

These PVDF fittings meet UL 94V0 for flame retardance, so they delay the spread of flames to valuable equipment. PVDF is comparable to Kynar, and has the chemical resistance to stand up to solvents and other harsh substances.

These fittings are an economical option for chemical waste systems. Fittings are ABS plastic, which has excellent strength and impact resistance and good chemical resistance.

These Schedule 40 fittings are the industry standard for gravity-flow drain, waste, and vent (DWV) applications.
