Made entirely of nickel-plated brass, these fittings have better corrosion resistance than unplated brass fittings.

A 316 stainless steel body gives these fittings the best corrosion resistance of all our metal push-to-connect tube fittings.

Ball bearings allow these fittings to rotate 360°, even after they are tightened. They have a special seal that reduces friction to allow for continuous rotation.

Suitable for use in air brake lines, these fittings meet Department of Transportation FMVSS 571 safety standards for low-temperature applications down to -40° F.

An all-metal body and built-in tube support allow these fittings to handle pressures up to 800 psi—the highest pressure rating of all our push-to-connect tube fittings.
