Tube Fittings for Vacuum Service
Proven Success through Product Test Reports
Tube fittings mitigate leakage in vacuum systems compared to NPT
Industry and Application
One of the most common questions we hear is whether our Swagelok Tube Fitting is rated for vacuum service. A customer recently experienced success with tube fittings in a vacuum furnace application. He was so thrilled with the performance of the tube fitting - he insisted we share!
The customer needed fittings, valves, and hose connections to allow 20 psig argon purge gas into a vacuum chamber, and then hold a a negative pressure of 0.1 millimeter of mercury (mm hg) manometric unit of measure. (1.0 x 10-1 Torr). Swagelok Minnesota demonstrated how tube fittings mitigate leakage compared to pipe fittings and provided product test reports to validate Swagelok tube fitting leak testing up to 1.8 x 10-6 Torr.
