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.

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

Give open-ended standoffs a finished look and protect them from dirt and debris.

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.

The threads on the tube end of these fittings are Class 3A or 3B and adhere to tighter tolerances than other 37° flared fittings.

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 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.

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.

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

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.

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.

Made of nickel-plated brass, these fittings have better corrosion resistance than unplated brass 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 Class 6000 fittings, these heavy duty forged fittings are the strongest steel fittings we offer.

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

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.

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

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

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

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

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

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

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

The male threads on these brass fittings have a sealant applied for extra protection against leaks. Also known as 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.

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

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

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.

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.

No groove required—press these rings onto the end of a shaft for a firm grip.

Also known as E-style rings.

Slide these rings into place with one twist—no tools required—for applications with high thrust loads.

Slide these rings into place by hand with a single twist for applications with high thrust loads.

Also known as E-Style and C-style rings, slide these into the groove from the side of the shaft. They provide a wider shoulder than other external retaining rings for a larger retaining surface.
