Viton O'ring bakeable to 200°C intermittently, sustained use to 150℃.
Vacuum seal of KF-series: O'ring compression by uniform pressure application around the 15° outer flange surface.
The vacuum seal of lSO-series is made by compressing the O'ring between the mating flanges. This done by alternately wrench-tightening opposing pairs of clamps or bolts until the first metal-to-metal contact is mode between the inner surfaces of the flanges and the spacing lips of the centering ring.
