Abstract
Face-sealed fittings are described for joining flanged tubes. These fittings utilize unique designs for pairing rings, nipples, and nuts to provide several advantages over prior art designs. Face-sealed fittings provided herein are symmetrical and genderless, and are field attachable/removable over previously welded glands. Moreover, they are torque free and have footprints comparable or smaller than legacy assemblies.
