Protect externally threaded components from contaminants during fabrication and storage.

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

Designed to fit into 37° flared connections such as those found on JIC and SAE fittings, these plugs protect internally threaded connections from contaminants during fabrication and storage.

Slip these inserts into tubular legs to quickly add threads for attaching leveling mounts. They’re often used in the legs of light equipment and furniture.

To provide corrosion resistance in wet environments, this framing is galvanized.

Twist these fittings onto high-vacuum tubing to quickly make sealed, high-vacuum connections without the need for clamping, welding, or tools.

Polished to a 15 Ra and under finish, these fittings have a mirror smooth interior. They are also known as ultra-high-purity fittings.

Create access points in ultra-high-vacuum lines or chambers by bolting two same-size flanges together with a copper gasket between them. The flanges’ sharp edges dig into the copper gasket and form an extremely tight seal, which means they handle higher vacuum pressures than other high-vacuum fittings with rubber gaskets.

A PTFE seal on the tube end of these fittings allows for an extra-strong connection in high-vibration applications.

Also known as luer lock couplings, these consist of a plug and socket that connect with a half turn. Use in low-pressure applications up to 30 psi.

An alternative to bolt-together fittings, these handle larger tube OD sizes and have higher vacuum ratings than quick-clamp fittings. Also known as ISO-K high-vacuum fittings, the clamps have claws that grab hold of fittings with flanged ends.

Also known as KF, QF, and NW fittings, these fittings are for high-vacuum applications, such as vacuum coating and heat treating, leak testing, and analyzing gases.

Polished to a 20 Ra finish, these fittings have an extra-smooth interior that prevents product buildup and inhibits bacteria growth.

No sleeve is required to assemble these fittings, which makes for a faster, more convenient installation compared to 37° flared fittings. They are also known as refrigeration and SAE fittings.

Crimp these fittings to copper tubing with a crimping tool for a leak-tight connection that doesn’t require heat or soldering. They are comparable to Viega ProPress fittings.

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

Thicker walls make these fittings—sometimes called flareless or bite fittings—withstand about twice as much pressure as standard compression fittings, so they’re good for hydraulic power applications.

With no latch, these couplings have a compact design to fit in small spaces. They can handle pressures up to 700 psi.

Fittings have good corrosion resistance.

These brass couplings have good corrosion resistance.

Quick-disconnect couplings consist of a plug and a socket that join with a latch so you can easily connect and disconnect your line. Use in applications up to 150 psi.

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.

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.

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

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.

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

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

Press these fittings onto stainless steel pipe using a crimping tool for a permanent, leak-tight connection that's faster than threading or welding and doesn't require heat.

The strongest socket-connect fittings we offer, these heavy duty forged fittings are also known as Class 6000.

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 Class 3000 fittings.

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

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

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

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

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

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

Use these unthreaded flanges in low-pressure applications. Also known as Class 125 flanges.

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

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

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

Use these heavy-duty brass fittings for high-pressure drinking water applications.

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

Also known as Silbraze fittings.

Couplings are metal, which has better durability than plastic cam-and-groove hose couplings. They consist of a plug and a socket that connect and disconnect quickly. Use them if you need frequent access to a line. To connect, insert the plug into the socket and push the levers down.

Attach these fittings to garden hose for a variety of water supply applications. They are metal for better durability than plastic garden hose fittings.

Thread these caps and plugs onto fire hydrants and washdown equipment to close off the line. They have rocker lugs for easy gripping.

These caps are the fastest way to close off or access your water line. They have a bracket that snaps into any type of 2 1/2 size female fire hose threads. Tap on one of the pin lugs to remove quickly in an emergency.

Join duct and fittings with quick-release clamps for faster disassembly and cleanout than other duct systems.

A spiral seam gives this duct greater strength and rigidity than standard duct.

Built to withstand temperatures up to 1000° F, these vent pipes and fittings are for use with boilers, furnaces, stoves, and other equipment that is fired by coal, gas, oil, propane, or wood.

The expanded mesh on these vent caps provides spark protection.

Cover exposed threads with these caps to help prevent bacteria growth in food processing areas and other sanitary environments.

Certified by EHEDG (European Hygienic Engineering and Design Group) to meet sanitary design standards, these cap nuts fit into tight spaces to cover and seal exposed threads in your food processing facility.

Keep moisture, dirt, and debris from entering your oil reservoirs.
