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

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

The thick walls of these fittings can withstand more than twice the pressure of standard compression fittings.

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

Use at pressures up to 1,500 psi.

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.

Transfer liquids and gasses into high-vacuum chambers with these assembled fittings, also known as feedthroughs.

Made of stainless steel, these couplings stand up to wet environments.
