The threads on these fittings have clockwise (right-hand) threads on one end and counterclockwise (left-hand) threads on the other end.

For extra leak protection in low-pressure lines, the threads of this Schedule 40 pipe have sealant already applied.

Assortments contain threaded pipe in various lengths.

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.

One end of these fittings has clockwise (right-hand) threads and the other has counterclockwise (left-hand) threads. Their galvanized finish gives them fair corrosion resistance.

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

A plastic sleeve prevents destructive corrosion when connecting different metals.

These fittings can stand up to high-pressure applications. Use them in noncorrosive environments.

Typically used with medium-pressure iron and steel threaded pipe fittings. Also known as Schedule 80.

Typically used with medium-pressure galvanized iron and steel threaded pipe fittings. Also known as Schedule 80.

Also known as no-hub pipe fittings and soil pipe fittings, these fittings are for use in gravity-flow applications both above and below ground.

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

Also known as no-hub couplings, these have a one-piece sleeve with a stop in the center, so you know your pipe is always aligned correctly.

With an FEP sleeve and PTFE sealing tape, these connectors withstand chemicals better than rubber connectors. Use them for joining low-pressure chemical waste drainpipe and fittings or transitioning between different chemical piping.

Use in medium-pressure applications up to 230 psi.

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.

These adapters connect PVC waste pipe to cast iron pipe without adding bulk. Instead of securing pipes together from the outside like clamp-on couplings, these flexible adapters fit into cast iron pipe to create a tight compression seal.

Connect male threaded pipe to these expansion joints to add a point of flexibility in your line that reduces stress, vibration, and noise.
