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

Typically used with extreme-pressure iron and steel threaded pipe fittings. Also known as Schedule XXH.

Typically used with high-pressure iron and steel threaded pipe fittings. Also known as Schedule 160.

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

The heavy duty caps and plugs in these assortments come in various sizes and stand up to high-pressure flow applications. Made of steel, they’re for use in noncorrosive environments.

Typically used with high-pressure galvanized iron and steel threaded pipe fittings. Also known as Schedule 160.

Typically used with thick-wall and high-pressure iron and steel unthreaded pipe fittings. Also known as Schedule 80.

Also known as Code 61 SAE hydraulic flanges.

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

Typically used with extreme-pressure iron and steel unthreaded pipe fittings. Pipe is also known as Schedule XXH .

Typically used with medium- to high-pressure stainless steel threaded pipe fittings.

Also known as Code 61 SAE hydraulic flanges.

Use these fittings in extreme-pressure conditions up to 15,000 psi.

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.

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

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

Typically used with high-pressure brass and bronze threaded pipe fittings.

Typically used with high-pressure brass and bronze threaded pipe fittings.

Typically used with high-pressure brass and bronze threaded pipe fittings.

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.

Install and remove these high-pressure brass fittings with a socket wrench or hex key (sold separately).

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

Typically used with medium-pressure brass and bronze threaded pipe fittings.

Typically used with high-pressure aluminum threaded pipe fittings.

Connect to thick-wall plastic pipe fittings for use in heavy duty industrial plumbing and water supply applications, such as water processing, waste water treatment, and irrigation. Pipe can handle pressures up to 900 psi.

Bolt two same-size flanges together with a gasket to create an access point within a line. They are also known as Pressure Class 150 flanges. They have thick, strong walls to handle heavy duty industrial plumbing and water supply applications, such as water processing, waste water treatment, and irrigation.

Use for pressures up to 200 psi. Also known as insert fittings, these slide into semi-flexible plastic pipe and secure with a clamp.

When used with high-pressure compression fittings and nuts, these sleeves bite into stainless steel tubing to form a strong seal.

These fittings have the highest pressure rating of all the Yor-Lok tube fittings we offer.

Polished to at least a 15 Ra finish on the inside, these fittings have an ultra-smooth interior surface that helps prevent contamination. They are also known as ultra-high-purity fittings.

Use these sleeves—also known as ferrules—with high-pressure compression nuts and fittings. They withstand about twice as much pressure as sleeves for standard compression fittings, so they’re good for hydraulic power applications.

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

An all-metal body and built-in tube support or dual seals allow these fittings to handle the highest pressure ratings of all our push-to-connect tube fittings.

Fittings have good corrosion resistance.

Prevent mixing the wrong high-pressure lines—these couplings are designed to only connect with a plug or socket of the same color.

Create custom couplings to save space and snake around obstructions. These couplings let you swap in different ends to change the connection size, type, and orientation to fit your specific setup.

Designed to handle high-pressure welding applications, these CGA fittings are commonly used to connect pressure regulators to compressed gas tanks or cylinders.

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.

Add quick connection points for mechanical gauges and other diagnostic equipment to your line. These couplings are also known as test ports and diagnostic couplings.

Larger, heavier, and rated for pressures up to 10,000 psi, these couplings maximize flow in high-pressure washing applications, such as water blasting.

The rocker lugs on these fittings allow for easy gripping, so you can quickly connect to fire hydrants and washdown equipment.

Also known as ground-joint couplings and boss couplings, these fittings are designed for high-pressure steam applications up to 600 psi. Insert the barbed end of the fitting into hose, then position the interlocking clamp over the hose and bolt into place. The clamp firmly grips your hose as it locks into the ring of the barbed end, creating a leak-tight seal.
