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.

Use at pressures up to 4,300 psi.

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.

Made of stainless steel, these fittings have better corrosion resistance than brass fittings.

Commonly used in high-pressure welding applications, these nipples connect your tank to the inlet of a pressure regulator. One side has a threaded pipe end and the other side has a rounded end that sits inside a threaded nut to make a threaded connection.

Use these couplings at pressures up to 10,000 psi. The plug and socket thread together to form a stronger connection than other quick-disconnect couplings. They are compatible with High-Pressure Thread-Lock-shape plugs and sockets.

Use these fittings with power washer guns and in other high-pressure water supply applications.

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.
