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

These fittings can stand up to high-pressure applications. Use them in noncorrosive environments.

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.

Forged for extra strength, these heavy duty unthreaded flanges can withstand high-pressure applications.

Butt-weld fittings allow for a smooth, flush connection that provides maximum flow.

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

For excellent strength in extreme-pressure applications, choose these heavy duty Pressure Class 1500 flanges.

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

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

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

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

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

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

These Schedule 40 fittings are the industry standard for gravity-flow drain, waste, and vent (DWV) applications.

A single sleeve (ferrule) bites into tubing as you tighten the nut, creating a strong seal.

These fittings have two sleeves for extra gripping power. They bite into steel tubing as you tighten the nut to form a strong seal.

Kits contain Industrial quick-disconnect plugs in four coupling sizes so you can determine the size of your couplings without needing to measure.

Also known as automotive couplings. Compatible with Tru-Flate-shape plugs and sockets.

Compatible with ARO-shape plugs and sockets.

Compatible with Schrader-shape plugs and sockets.

Compatible with Ring-Lock-shape plugs and sockets.

These couplings have a lower profile than other claw-style couplings to fit in cramped spaces. They consist of a plug and a socket that connect with a quarter twist. Also known as Bowes couplings.

Use these couplings at pressures up to 5,000 psi. They consist of a plug and socket that connect and disconnect quickly. Use them if you need frequent access to a line. They are compatible with International Standard ISO B-shape plugs and sockets.

Use these couplings at pressures up to 10,000 psi. Also known as flush-face couplings, the plugs and sockets have a flat face, which allows them to mate close together, reducing fluid loss when connecting and disconnecting the line. They are compatible with High-Pressure Minimal-Spill-shape plugs and sockets.

Use these couplings at pressures up to 3,000 psi. They consist of a plug and socket that connect and disconnect quickly. Use them if you need frequent access to a line. They are compatible with Pioneer-shape plugs and sockets.

Fittings are threaded on both ends so you can connect them directly to a threaded hose or to pumps, cylinders, and other equipment in your hydraulic system. Use in high-pressure applications up to 6,000 psi

An isolated ground connection on these outlets protects computers and other sensitive equipment from external signals that interfere with the equipment’s performance.

Also known as hospital-grade outlet strips, these outlets have an extra-tight fit to prevent plugs from detaching. They are marked with a green dot.

Mount these strips into standard 19" wide electronics racks and enclosures.

These plugs withstand temperatures up to 600° F to protect internally threaded NPT connections from contaminants during electropainting, paint baking, and powder coating applications.

Made of steel, these are our most durable plugs for panels. Tapered prongs snap into the hole to securely hold them in place.

Keep chips and shavings from clogging or damaging unused holes on fixture plates in milling machines.

More durable than plastic caps, these provide the most protection from abrasion and impact.

Weld these caps and targets to the ends of posts to create stackable shelving and racking systems.

A circular groove quickly centers plug in unused holes and knockouts.

Sized for 22 mm and 30 mm push-button holes.

Stronger than aluminum cord grips, these grips are zinc plated for corrosion resistance.

Stronger than aluminum cord grips, these steel grips are zinc plated for corrosion resistance. They have a steel locknut and metal-reinforced O-ring that prevents liquid from entering the connection.

These steel screws are available with corrosion resistant finishes. A rubber-bonded washer compresses to form a watertight seal. They save you time and effort by drilling their own holes and fastening in a single operation.

These steel screws are zinc plated to resist corrosion in wet environments.

The neoprene-backed washer seals out contaminants.

Male and female snaps are included to create complete snaps.

Easily view liquid movement and level changes from a distance—these sights have an indicator ball inside the glass window.

With a thick glass window fused to a metal body, these sights resist cracking at high pressures.

Assortments contain straight, 45° elbow, and 90° elbow fittings.

Keep thin grease from leaking out—the check valve on these fittings has a Buna-N seat that creates a tighter seal than check valves on other grease fittings.

Often used on earth movers, mining equipment, and other heavy machinery, these fittings have a T-shaped top that holds the dispensing tip in place so it won't pop off when adding grease.

Ensure a secure fit in unthreaded holes—these fittings cut threads as they’re installed. Use these fittings in tight spaces where protruding fittings won't work.

Drive these fittings into unthreaded holes. They're also known as hydraulic grease fittings.

Lubricate multiple points from a single location.

Remove worn fittings and repair threaded holes.
