These weld-on UV grade, zero length fused silica viewports have a 1.5 inch diameter weldable stainless steel flange. Weld-on fittings are used for permanent, non-alterable ultra-high vacuum applications. These fittings use a welded stainless steel bead to achieve the high vacuum seal and can operate down to 10-13 torr (10-11 Pa) and can be heated to 200 °C for bake-out. These vacuum fittings are made of corrosion resistant stainless steel.
