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.

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

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

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

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

Use at pressures up to 1,500 psi.

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

Create a strong connection without heating, flaring, or soldering.

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

These Monel fittings have the corrosion resistance to handle hydrofluoric and sulfuric acid. Also known as instrumentation fittings, they include a nut with two sleeves.
