Bolt two same-size flanges together with a gasket to create an access point within a line. Flanges are an economical option for gravity-flow chemical waste systems. They are ABS plastic, which has excellent strength and impact resistance and good chemical resistance.

Also known as manifold flange fittings, these have a clamp-together design that lets you access your line for routine maintenance. Fittings resist acids, solvents, and other harsh chemicals. They won’t deteriorate when exposed to the damaging effects of ultraviolet light, so they’re suitable for outdoor use.

These fittings are NSF certified for use in corrosive waste gravity-flow systems. Made of CPVC, they have better chemical resistance than ABS plastic gravity-flow fittings and can stand up to highly-corrosive acids and other harsh substances.

These fittings have excellent corrosion resistance to handle a wide range of acids and other highly-corrosive chemicals. They are commonly used in metal surface treating applications, plating solution lines, and other chemical process applications. Reinforced with layers of fiberglass, they have better strength and durability than any of our other pipe fittings for chemicals.

These PVDF fittings meet UL 94 V-0 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.

Made of corrosion-resistant plastic, these fittings won’t deteriorate when used in oil applications. They have high strength and impact resistance.

With thinner walls than Schedule 40 fittings, these are lighter in weight and have more space on the inside for high-flow applications, such as underground gravity-flow sewer and storm drainage lines. They are also known as SDR 35 fittings.

Bolt two same-size flanges together with a gasket to create an access point within a line. Also known as Schedule 40 flanges, they are the industry standard for gravity-flow drain, waste, and vent (DWV) applications.

Joints are for two-way flow and are brass for good corrosion resistance.

Joints are for one-way flow and are brass for good corrosion resistance.

Joints are for two-way flow and are meant to be used when you need the supply line and the return line to be on the same side of your equipment.

Joints are for one-way flow and are stainless steel for excellent resistance to corrosion caused by fluid flowing through them.

A 316 stainless steel body gives these fittings the best corrosion resistance of all our metal push-to-connect tube fittings.

Make lightweight connections without the hassle of matching the exact thread type—these fittings connect to NPT, NPTF, BSPP, BSPT, and other universal threads.

Often used in outdoor, damp, and washdown environments, these 316 stainless steel fittings will not corrode from water, salt, or chemicals. The male threaded ends mate with NPT, NPTF, BSPT, BSPP, and other universal threads, so you won’t have to worry about matching exact threads when you’re on the job.
