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.

Unlike other manifolds, which have an inlet on either end, these have one inlet on the opposite side from the outlets. This design allows air or fluid to follow a straight path, improving flow through your system. Also known as headers.

Minimize leaks in your line—these fittings have a single barb that creates a smooth clamping surface for extra-tight connections.

Use these couplings at pressures up to 5,000 psi. They consist of a plug and socket that connect and disconnect quickly. Use them if you need frequent access to a line. They are compatible with International Standard ISO B-shape plugs and sockets.

Connect these orifices to threaded pipe, or insert them into threaded holes.

Connect male- and female-threaded parts of different thread types and sizes, while allowing air, liquids, wire, or other thin materials to pass through.

Made of 18-8 stainless steel, these inserts have better corrosion resistance than black-phosphate steel.

These inserts are the most corrosion-resistant thread-locking inserts we offer.

A closed-end tap, drill bit, and installation bit are included with these inserts.

Made of 18-8 stainless steel, these inserts have good corrosion resistance.

Projections on the base concentrate the weld and provide room for heat to dissipate.

Weld these nuts to stainless steel surfaces.

These nuts can be used in channels and tight spaces where round-base weld nuts won't fit.

Weld these nuts to flat and uneven uncoated steel surfaces for a strong permanent hold.

Square weld nuts have more weld points than hex weld nuts for a stronger hold. Use them on flat surfaces.

Weld these nuts to stainless steel surfaces.

Weld these nuts to round uncoated metal tubes to attach threaded parts, such as rod ends.
