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

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

Choose these fittings when you want the same high-quality found in our low-pressure pipe fittings, but need more strength to handle higher pressures.

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.

Extreme pressures are no problem for these heavy-duty brass 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.

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.

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

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.

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.

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.

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.

These fittings are an economical option for chemical waste systems. Fittings are ABS plastic, which has excellent strength and impact resistance and good chemical resistance.

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.

Polished to a 15 Ra and under finish, these fittings have a mirror smooth interior. 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 fittings have better corrosion resistance than unplated brass fittings.

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.

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.

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.

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.

These standoffs are made to NAS specifications.

Turn sockets with a bit screwdriver.

Attach one of these adapters to a socket to turn it with an open-end or box wrench.

Use hex-shank bits (also known as insert bits) in powered tools.

The head is angled 90° to drive fasteners in tight spaces. Use these adapters to hold hex-shank bits (also known as insert bits) in powered tools.

Keep bits from slipping. Insert a bit into the adapter, place a screw on the end of the bit, and slide the adapter sleeve over the screw. The sleeve retracts as the screw is driven. These adapters hold hex-shank bits (also known as insert bits) in powered tools.

Attach these adapters to square-drive tools.

Use a 4 mm bit in a bit driver that's designed for 1/4" bits.

Designed to withstand high torque and force, these adapters fit the square drive on impact wrenches. Use with hex-shank bits (also known as insert bits).

Less likely to crack or shatter under high torque than standard bits, these are often used with power tools to install machine screws.

Convert a power screwdriver or impact driver into a versatile drill. Also known as adapt-a-drive, these chucks have a 1/4" hex shank that fits the hex drive in most power screwdrivers and impact drivers.

Drill extremely small holes with a drill press using these adapters. The shank fits into a collet or adjustable drill chuck, and the other end securely holds a wire gauge drill bit.
