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

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).
