About half the strength of medium-strength steel coupling nuts, these nuts are for light duty fastening applications.

These coupling nuts have good chemical resistance.

One-third the weight of steel, aluminum coupling nuts resist corrosion in wet environments.

Plastic coupling nuts are chemical resistant, nonconductive, and lightweight.

Stainless steel coupling nuts have excellent corrosion resistance in most environments.

Change thread sizes or types, such as fine to coarse threads, on parts without changing gender.

Change inch threads to metric with these adapters, or swap metric threads for inch. An external hex lets you tighten or loosen them with a wrench.

Need to join two female-threaded parts, such as coupling nuts, with dissimilar inch thread sizes? Attach them to these adapters and tighten the exterior hex nut for a secure connection.

Connect two differently sized male-threaded parts, such as threaded rods, and tighten with a standard wrench.

Less than an inch in length, these miniature fittings work well in low-pressure pipe lines that are tight on space.

When space is at a premium choose these compact fittings.

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.

Made of plastic, these couplings are lighter in weight than metal quick-turn couplings.

Made of stainless steel, these couplings stand up to wet environments.

A 316 stainless steel body gives these fittings the best corrosion resistance of all our metal push-to-connect tube fittings.

Made of nickel-plated brass, these fittings have better corrosion resistance than unplated brass fittings.

Ball bearings allow these fittings to rotate 360°, even after they are tightened. They have a special seal that reduces friction to allow for continuous rotation.

Fittings have good corrosion resistance.

Aluminum fittings have good corrosion resistance, but are lighter in weight than brass.

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

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

With no latch, these couplings have a compact design to fit in small spaces. They can handle pressures up to 700 psi.

Fittings have a barb that grips onto tubing. Use in applications up to 120 psi.

Metal hose fittings have better durability than plastic barbed hose fittings.

These stainless steel anchor studs offer excellent corrosion resistance.

A black-oxide finish provides mild corrosion resistance.
