For light duty applications, choose these metric-sized coupling nuts.

Made from Grade 5 steel, these inch-sized coupling nuts are suitable for most applications.

Made from Grade 8 steel, these nuts are about 25% stronger than medium-strength steel coupling nuts. Furnished in inch thread sizes.

Comparable in strength to Grade 9 bolts, these coupling nuts are about 20% stronger than high-strength steel coupling nuts. Available in inch thread sizes.

These metric coupling nuts have good chemical resistance.

More corrosion resistant than 18-8 stainless steel coupling nuts, these metric nuts have excellent resistance to chemicals and salt water.

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

Known for their strength, steel coupling nuts are available with a corrosion-resistant finish.

A smooth rounded body provides a finished look.

Increase or decrease metric thread size from one male-threaded part to another. Commonly used to connect two differently sized threaded rods, they have a hex-shaped body, so you can tighten them with a standard wrench.

Adapt threaded rods from inch to metric. These adapters connect two male-threaded fasteners, so you can change the gender of a mating part or increase or decrease its thread size. The hex-shaped body fits into the head of a standard wrench.

In addition to joining male- and female-threaded parts, these adapters can increase or decrease metric thread sizes and change the thread pitch.

The through hole allows you to connect float rods to float valves.

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

These standoffs are made to NAS 1829 specifications.

Protect components from electrical charges.

Choose these standoffs for their adherence to NAS 1831 specifications.

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

These fittings are strong enough to handle extreme pressures, yet small enough to fit into cramped spaces.

The strongest steel fittings we offer, these can withstand extreme-pressure applications.

A galvanized finish gives these fittings better corrosion resistance than our plain steel high-pressure fittings. Also known as Class 3000 fittings.

A galvanized finish gives these fittings fair corrosion resistance. They have the strength to handle medium-pressure applications.

Crimp these fittings onto steel pipe to form a tightly sealed connection that’s faster than threading or welding and doesn’t require heat.

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

Use these fittings in extreme-pressure conditions up to 15,000 psi.

Not only do these brass fittings have the strength to handle high-pressure applications, the male threads have a sealant applied for extra protection against leaks.

When space in your pipe line is limited, choose these miniature fittings that are one inch or less in length.

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

The polished chrome plating not only has a shiny appearance, but also improves corrosion resistance on these Class 125 fittings.

Choose these fittings when you need better strength than our low-pressure brass and bronze pipe fittings.

Also known as Class 3000 fittings, these have the highest pressure rating of all the aluminum pipe fittings we offer.

Connect these fittings to standard-wall plastic pipe for use in low- to medium-pressure applications up to 750 psi.They are the industry standard for residential and commercial plumbing and water supply applications.

Made of polypropylene, these fittings won’t deteriorate when exposed to the damaging effects of ultraviolet light and are suitable to use outdoors. They have the chemical resistance to withstand acids, solvents, and other harsh substances.

Extreme temperatures are no problem for these fittings—they’re made of PTFE, so they can withstand a wider temperature range than any of our other plastic pipe fittings for chemicals. They are commonly used in high-purity chemical flow processes, such as semiconductor and clean room applications.

Use these plastic fittings to connect gasoline fuel lines to machines and equipment. They have excellent corrosion resistance as well as high strength and impact resistance.
