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

Unlike other stainless steel fittings, these are made in the U.S.A. for superior quality. As another marker of quality, they come with a certificate with a traceable lot number and test report that guarantees material composition.

When space is at a premium choose these compact fittings.

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

Socket-connect fittings are easier to weld than butt-weld fittings because the fitting doesn't need to align perfectly to the pipe. Slip the pipe into the socket and weld.

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.

Install and remove these high-pressure brass fittings with a socket wrench or hex key (sold separately).

The male threads on these brass fittings have a sealant applied for extra protection against leaks. Also known as Pressure Class 125 fittings, they are built for use in low-pressure applications.

Used in low-pressure pipe lines, these brass fittings have a plating that makes them shiny and improves corrosion resistance.

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.

Also known as Silbraze fittings.

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

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

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.

The male threads on these fittings have a sealant applied for extra leak protection.

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

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

Socket-connect fittings are easier to weld than butt-weld fittings because the fitting doesn't need to align perfectly to the pipe. Slide the pipe into the socket and weld.

Also known as Pressure Class 6000 fittings, these heavy duty forged fittings are the strongest steel fittings we offer.

Designed for medium-pressure applications, these fittings have better strength than our low-pressure aluminum pipe fittings.

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

Watch water flow through your line. These fittings are compatible with Schedule 40 pipe, the industry standard for residential and commercial low-pressure plumbing and water supply.

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

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.

These PVDF fittings meet UL 94 V-0 for flame retardance, so they delay the spread of flames to valuable equipment. PVDF is comparable to Kynar, and has the chemical resistance to stand up to solvents and other harsh substances.

Made of polypropylene, these gravity-flow fittings withstand organic solvents, such as acetone, that would dissolve CPVC pipe. They also stand up to highly corrosive acids, such as hydrochloric acid, and alkalies.

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.

Made of PVDF, also known as Kynar, these fittings stand up to the harsh chemicals used to clean food processing lines. Unlike other plastic fittings, such as nylon and acetal fittings, they’ll resist degrading when exposed to strong alkali and highly acidic solutions.

Polished to at least a 15 Ra finish on the inside, these fittings have an ultra-smooth interior surface that helps prevent contamination. They are also known as ultra-high-purity fittings.

The external hex bolt on these fittings allows for easy installation in cramped spaces. They are also known as banjo-style fittings and JIC (Joint Industrial Council) fittings. They provide a tight seal on tubing that is flared to 37°.

Made of nickel-plated brass, these tube fittings resist corrosion better than plain brass fittings. The male threaded ends connect to NPT, NPTF, BSPP, BSPT, and other universal threads, so you don’t have to bother matching exact thread types.

These fittings won’t absorb moisture, so they’re good for water and high-humidity air applications.

Designed for use in welding applications, these fittings are flame retardant.

Use these luer lock couplings to quickly connect low-pressure air and water lines. Made of stainless steel, they’re more durable than plastic couplings.

Low-profile barbs and a longer first barb allow for a smoother, easier installation than other barbed fittings. Slide the barbed end into hose and secure with a clamp.

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.

One side inch, one side metric, and a hex in the middle—these handy fasteners connect two female-threaded parts, such as coupling nuts, adapting from inch threads to metric. Tighten with a standard wrench.

Join two female-threaded parts of various thread types and sizes, while allowing air, liquids, wire, or other thin materials to pass through.

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.

Often called sleeve nuts, these thread adapters fasten parts with right-hand threads to parts with left-hand threads.

Carry fewer impact sockets—these five reversible impact sockets turn 10 fastener sizes. Flip the socket around to turn a different size.

Convert your standard 6-point sockets into hex bit sockets with these bits.

Made in the U.S.A., these tools handle the toughest industrial applications, provide the best grip on fasteners, and have a superior finish.

Made in the U.S.A., these tools handle the toughest industrial applications, provide the best grip on fasteners, and have a superior finish.

Switch out worn or damaged bits instead of replacing your entire bit socket.

Assortments contain bits with multiple drive styles.
