Swagelok tube fittings deliver a leak-tight, gas-tight seal that is resistant to vibration fatigue, even in harsh environments or stressful applications. They withstand high pressures and temperature extremes and are easy to install, disassemble, and reassemble in a variety of situations. Swagelok tube fittings can be used on thick- or thin-walled, hard or soft tubing and resist the effects of pressure and thermal cycling.
