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

Typically used with low-pressure stainless steel threaded pipe fittings.

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

Typically used with low-pressure stainless steel threaded pipe fittings.

Choose these fittings when you want the same high-quality found in our low-pressure pipe fittings, but need more strength to handle higher pressures.

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

Also known as Code 61 SAE hydraulic flanges.

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.

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.

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

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

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

The male threads on these brass fittings have a sealant applied for extra protection against leaks. Also known as Pressure Class 125 fittings, they are built for use in low-pressure applications.

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

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

Plated with nickel, these brass fittings resist rust better than steel and unfinished brass fittings. Select them when you need more strength in corrosive environments to handle higher pressures than our low-pressure fittings.

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

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

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.

Also known as Schedule 40, this steel pipe is designed for low-pressure applications.

Pipe has clockwise (right-hand) threads on one end and counterclockwise (left-hand) threads on the other end. When you use a wrench to turn, connections on both ends tighten at the same time.

The threads on these fittings have clockwise (right-hand) threads on one end and counterclockwise (left-hand) threads on the other end.

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

Made of galvanized steel, this Schedule 40 pipe has fair corrosion resistance and is designed for low-pressure applications.

Assortments contain threaded pipe in various lengths.

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.

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

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

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

A galvanized finish gives these fittings fair corrosion resistance. They have the strength to handle medium-pressure applications.

This steel pipe has grooved ends that connect to fittings with a clamp (sold separately) for an easy way to install piping systems.

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