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.

These fittings can stand up to high-pressure applications. Use them 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.

Use at pressures up to 4,300 psi.

For applications that require an extra level of cleanliness, these fittings are individually bagged to prevent contamination.

The male pipe threads on these fittings have a sealant applied for extra protection against leaks.

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

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

The flat face of the fitting connects to a tube adapter so you can slide the tubing and fitting sideways to disconnect in cramped spaces. They are also known zero-clearance fittings.

With a nickel-plated finish, these compression fittings resist corrosion better than plain brass fittings.

The sleeve in these fittings is rubber instead of metal, so it cushions the tubing and absorbs vibration while creating a tight seal.

The external hex bolt on these fittings allows for easy installation in cramped spaces.

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.

A tube adapter sits flush against the flat face of the fitting so you can slide the steel tubing and fitting sideways to disconnect in cramped spaces. Also known as zero-clearance fittings.

With the best corrosion resistance of any metal fitting we offer, these Hastelloy fittings will stand up to aggressive chemicals and are resistant to pitting and stress cracking. Also known as instrumentation fittings, they include a nut with two sleeves.

The external hex bolt on these fittings allows for easy installation in cramped spaces. They are also known as banjo-style fittings and JIC (Joint Industrial Council) fittings. They provide a tight seal on tubing that is flared to 37°.
