More durable than plastic plugs, these provide the most protection from abrasion and impact. Use them to eliminate sharp edges and create a finished look on metal fence and machine-guard posts. Drive them in place with a hammer for a secure fit.

Seal tube and hose fittings to keep their straight threads protected from contaminants during fabrication and storage.

Keep metal snap-in plugs of various sizes on hand to solve whatever problems arise. Made of steel, these plugs are our most durable plugs for panels. Their tapered prongs snap into holes to securely hold them in place.

Protect externally threaded components from contaminants during fabrication and storage.

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

Also known as I-line fittings, the flanged end of the male adapter on these high-polish fittings interlocks with the flanged end of the female adapter to provide extra support to your line.

Use these fittings at pressures up to 9,700 psi. Also known as instrumentation fittings, they are made to tight tolerances for use in high-precision applications. They are compatible with Swagelok®, Let-Lok, and Parker A-Lok fittings.

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

Fittings are polished to a32 Ra and under finish on the interior.

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

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

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.

Solder these fittings to tubing for a permanent, leak-tight connection. They are also known as sweat fittings.

Also known as instrumentation fittings, these are made to tighter tolerances than standard compression fittings. They are compatible with Parker CPI fittings.

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

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.

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

Bolt two flanges of the same size together with a gasket to create an access point in 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. Slide the pipe into the socket and weld.

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

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

Use these fittings for low-pressure applications in noncorrosive environments.

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

The strongest steel fittings we offer, these can withstand extreme-pressure applications.

For use in noncorrosive environments, these fittings have better strength than our low-pressure iron and steel pipe fittings.

Also known as Schedule 40 fittings, these have thicker walls than our thin-wall aluminum unthreaded pipe fittings.

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

Use these heavy duty, corrosion-resistant fittings in high-pressure flow applications.

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.

Also known as Code 61 SAE hydraulic flanges.

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

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.

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

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.

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 caps to hold components in place and protect shaft ends.
