Pipe has clockwise (right-hand) threads on one end and counterclockwise (left-hand) threads on the other end. When you use a wrench to turn, connections on both ends tighten at the same time.

Made of galvanized steel, this Schedule 40 pipe has fair corrosion resistance and is designed for low-pressure applications.

Assortments contain threaded pipe in various lengths.

This steel pipe has grooved ends that connect to fittings with a clamp (sold separately) for an easy way to install piping systems.

Typically used with low-pressure stainless steel threaded pipe fittings.

Typically used with standard-wall aluminum unthreaded pipe fittings.

Typically used with low-pressure brass and bronze threaded pipe fittings.

Typically used with low-pressure brass and bronze threaded pipe fittings.

Also called close nipples, these Schedule 40 nipples are threaded on both ends to the center.

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 this pipe to standard-wall plastic pipe fittings in low- to medium-pressure applications up to 810 psi. It is typically used in residential and commercial plumbing and water supply applications.

With thicker, stronger walls than standard-wall pipe, this Schedule 80 pipe can handle heavy duty industrial plumbing and water supply applications, such as water processing, waste water treatment, and irrigation. Use for pressures up to 550 psi. Suitable for outdoor environments, it contains an additive that protects against the damaging effects of ultraviolet light. Connect to UV-resistant PVC pipe fittings.

This pipe is an economical choice for gravity-flow chemical waste systems. Pipe is 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.

This pipe has thinner walls than Schedule 40 pipe, so it’s lighter in weight and has more space on the inside for high-flow applications, such as underground gravity-flow sewer and storm drainage lines.

A polyester braid is embedded into the walls of this tubing, giving it the strength to withstand higher pressures than other soft tubing for air and water. Use in applications up to 350 psi.

Multiple colors allow you to color-code your lines for easy identification.

Strong, hard walls give this tubing extra support in high-pressure and vacuum applications.

Tough and durable, this tubing resists abrasion and tearing.

Vent smoke, water-based paint fumes, and welding fumes with this hose that gives you a clear view inside your line.

Rugged, yet pliable PVC makes this a good general purpose hose for venting smoke, propane fumes, and water-based paint fumes.

Also known as Type A, this conduit meets the demands of continuous motion while sealing out liquid when used with liquid-tight fittings.
