Swagelok Medium- and High-Pressure Tube Fittings

Medium-Pressure, Gaugeable Tube Fittings and Adapter Fittings (FK Series)

The simple two-piece design of the Swagelok patented medium-pressure tube fittings and adapters consists of a female fitting body and preassembled cartridge containing the male nut and color-coded front and back ferrules on a disposable plastic arbor. The preassembled cartridge ensures installers correct ferrule orientation, visual confirmation of ferrule presence, and easy and proper installation into the female body. The Swagelok medium-pressure tube fitting offers a leak-tight gas seal and vibration resistance in applications up to 20 000 psig (1378 bar). See the details of the design.
