304 Stainless Steel—Fittings hold up in humid, damp, and washdown environments but will corrode if exposed to salt water or chemicals.

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.

High-Pressure Brass and Bronze Threaded Pipe Fittings

High pressures are no problem for these heavy-duty fittings. They are brass for good corrosion resistance.

Straight Connectors

Black-Zinc-Plated 360 Brass—Black zinc–plated brass pipe has a shiny finish that offers better corrosion resistance than nickel-plated brass and stands up to salt-spray applications.

Chrome-Plated 360 Brass—Chrome-plated brass pipe has a mirror-like finish and provides better corrosion resistance than nickel- and black zinc–plated brass.

Nickel-Plated 360 Brass—Nickel-plated brass pipe provides better corrosion resistance than unplated brass.

Precision Extreme-Pressure Stainless Steel Threaded Pipe Fittings

Made to tighter tolerances than other stainless steel pipe fittings, these are also known as instrumentation fittings. The male threads are rolled for extra strength in extreme-pressure applications. Fittings are commonly used to connect equipment in gas and hydraulic fluid lines.

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.

Thick-Wall Plastic Pipe Fittings for Water

Connect these fittings to Schedule 80 pipe. With thicker, stronger walls than standard-wall fittings, they can handle heavy duty supply applications, such as water processing, wastewater treatment, and irrigation. Fittings are plastic for good corrosion resistance. They meet ASTM specifications and testing requirements for material quality.

Warning: Never use plastic pipe fittings, flanges, and pipe with compressed air or gas.

Note: For fittings that are not rated for pressure, you can use the pressure rating of the plastic pipe as a reference. Threaded fittings are limited to 50% of the rated pressure of the pipe.

High-Pressure Brass and Bronze Threaded Pipe Nipples and Pipe

Use this extra-strong pipe in a high-pressure line. It is brass for good corrosion resistance. The plating on this pipe creates a shiny finish and provides extra protection in corrosive environments. It has the strength to handle high-pressure applications.

Pipe—Fully Threaded

Fully threaded pipe is also known as a close nipple; it is threaded on each end to the center.

Black-Zinc-Plated 360 Brass—Black zinc–plated brass pipe has a shiny finish that offers better corrosion resistance than nickel-plated brass and stands up to salt-spray applications.

Chrome-Plated 360 Brass—Chrome-plated brass pipe has a mirror-like finish and provides better corrosion resistance than nickel- and black zinc–plated brass.

Nickel-Plated 360 Brass—Nickel-plated brass pipe provides better corrosion resistance than unplated brass.

Crack-Resistant PFA Pipe Fittings for Harsh Chemicals

Not only do these PFA fittings have the chemical resistance to handle acid and salt water, they also have better crack resistance than other plastic pipe fittings for chemicals. Also known as Schedule 80 fittings, they have thick, strong walls to handle heavy duty chemical processing applications. Fittings have a super-smooth interior for unrestricted flow. They are commonly used in high-purity chemical flow processes, such as semiconductor and clean room applications, because the material won’t leach contaminates into the line.

Warning: Never use plastic pipe fittings, flanges, and pipe with compressed air or gas.
