Vacuum components -
vacuum flanges ISO
Most of our ISO parts that come into contact with vacuum are made of stainless steel. We have many fittings on stock. Such as clamps, O-rings, reductions, soldering flanges, blind flanges. What we do not have on stock we can often deliver within a week.
The components of ISO universal flange system are defined by the International Standards Organization (ISO). The construction of ISO flange series includes two smooth-faced flanges clamped together with a metal centering ring and an elastomer O-ring between them. ISO components are reusable and changeable with other ISO dimension components of the same size.
