Also known as Schedule 40, this steel pipe is designed for low-pressure applications.

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.

Use these fittings for low-pressure applications in noncorrosive environments.

To prevent leaks in low-pressure lines, the male threads on these fittings have an acrylic sealant already applied for extra protection.

Suitable for use in fire-protection applications, these pipe fittings are made of cast iron, so they are brittle and can be quickly opened with the strike of a sledge hammer.

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

The acrylic sealant on this pipe offers extra protection against leaks. Also known as schedule 40 pipe, this pipe is designed for use in low-pressure environments.

The galvanized finish on these fittings provides fair corrosion resistance. Fittings are for use in low-pressure applications.

Press these fittings onto stainless steel pipe using a crimping tool for a permanent, leak-tight connection that's faster than threading or welding and doesn't require heat.

Keep a variety of lengths of pipe and pipe nipples on hand for areas where corrosion is a concern.

Unlike other stainless steel fittings, these are made in the U.S.A. for superior quality. As another marker of quality, they come with a certificate with a traceable lot number and test report that guarantees material composition.

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

Use these heavy duty, corrosion-resistant fittings in high-pressure flow applications.

Typically used with low-pressure aluminum threaded pipe fittings.

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

Use these fittings in low-pressure flow applications. They have good corrosion resistance.

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 Schedule 40 plastic pipe—they are the industry standard for residential and commercial low-pressure plumbing and water supply applications. They are plastic for good corrosion resistance.

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

Made of polypropylene, these gravity-flow fittings withstand organic solvents, such as acetone, that would dissolve CPVC pipe. They also stand up to highly corrosive acids, such as hydrochloric acid, and alkalies.
