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.

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

Also known as freeze plugs, these are commonly used to permanently seal the shallow holes left in a component during the casting process.

Permanently seal unthreaded holes in pneumatic and hydraulic components.

Protect externally threaded components from contaminants during fabrication and storage.

The smooth finish inside these stainless steel quick-clamp fittings makes it easy to remove product residue.

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

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.

Also known as JIC (Joint Industrial Council) fittings, these provide a tight metal-to-metal seal on stainless steel tubing that is flared to 37°.

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

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

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

For high-vacuum systems with tube sizes too large for quick-clamp (KF) fittings, choose these bolt-together 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.

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.

Choose these metal fittings when you need better durability than our plastic push-to-connect fittings.

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.

Also known as JIS (Japanese Industrial Standard) fittings.

A 316 stainless steel body gives these fittings the best corrosion resistance of all our metal push-to-connect tube fittings.

Made of stainless steel, these couplings stand up to wet environments.

Fittings have good corrosion resistance.

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

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.

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

These flanges are for low-pressure applications in noncorrosive environments.

The galvanized finish on these Pressure Class 150 flanges provides fair corrosion resistance.

These fittings are strong enough to handle extreme pressures, yet small enough to fit into cramped spaces.

Combine an adapter with a two-piece pipe flange (sold separately) to build a customized flange connection for noncorrosive environments.

Also known as Pressure Class 1500 steel flanges, these have the strength to handle high pressures.

Also known as Pressure Class 300 flanges, these medium-pressure flanges have a galvanized finish for fair corrosion resistance.

With better strength than our low-pressure steel flanges, these are for use in medium-pressure applications.

Also known as ANSI flanges.

Also known as Code 61 SAE hydraulic flanges, these let you create an access point in a high-pressure hydraulic line.

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

Also known as Pressure Class 150 flanges, these corrosion-resistant flanges are designed for low-pressure pipe applications.

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

When space is at a premium choose these compact fittings.

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.

Bolt two same-size flanges together with a gasket to create an access point within a pipe line.

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.

Use these heavy duty forged flanges for high-pressure applications.

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

Also known as Pressure Class 125 flanges, these are for use in low-pressure applications. Flanges are aluminum, which is lightweight with good corrosion resistance.

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

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

Also known as Pressure Class 150 flanges, these brass flanges are designed for low-pressure applications.

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.

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

Bolt these flanges to another same-size flange with a gasket to create an access point within a pipe line. They are also known as Silbraze flanges.

Use these retaining caps to secure the ends of quick-release pins in holes that are oversized or out of round.

Provide a connection for hose cocks, needle valves, and nozzles by attaching these flanges and turrets to your supply pipe.
