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

The left-hand threads on these coupling nuts resists loosening from counterclockwise vibration. Use in light duty applications.

Choose these locknuts to fasten standard metric threads. They’re Class 8 steel, so they can be used in most fastening applications.

These metric-sized coupling nuts are Class 10 steel, so they’re about 25% stronger than medium-strength steel coupling nuts.

These coupling nuts have good chemical resistance.

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

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.

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

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

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.

These standoffs are made to NAS specifications.

Choose these standoffs for their adherence to NAS 1831 specifications.

Use these corrosion-resistant fittings in a low-pressure pipe line.

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

These fittings are made to tighter tolerances than other stainless steel pipe fittings. They are also known as instrumentation fittings.

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

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

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

Made to tighter tolerances than other steel pipe fittings, these are also known as instrumentation fittings.

For use in noncorrosive environments, these fittings have better strength than our low-pressure iron and steel pipe fittings.

Use these unions to connect different metals in a piping or plumbing system. They have a gasket with a plastic sleeve that inhibits destructive corrosion.

In addition to being lightweight, these aluminum fittings offer good corrosion resistance. Use them in low-pressure flow applications.

These brass fittings have the strength to handle high-pressure applications.

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.

The plating on these brass fittings creates a shiny finish and provides extra protection in corrosive environments. Fittings have the strength to handle high-pressure applications.

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

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

Plated with nickel, these brass fittings resist rust better than steel and unfinished brass fittings. Select them when you need more strength in corrosive environments to handle higher pressures than our low-pressure fittings.

Also known as instrumentation fittings, these have the most precise threads and the tightest tolerances of all the brass pipe fittings we offer.

Connect these fittings to thick-wall plastic pipe—they have thicker, stronger walls than standard-wall fittings, so they can handle heavy duty industrial plumbing and water supply applications, such as water processing, waste water treatment, and irrigation. They can withstand pressures up to 900 psi.

Connect to CPVC pipe for use in high-temperature plumbing and water supply applications up to 200° F.

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.

Not only do these PFA fittings have the chemical resistance to handle acid and salt water, they also have better crack resistance than other plastic pipe fittings for chemicals. They are commonly used in high-purity chemical flow processes, such as semiconductor and clean room applications.
