The difficulty in obtaining
high quality 316L stainless steel flanges, with reliable knife-edges and
seal faces has driven us to extend the range manufactured at our own
facility. We now offer the most popular sizes in our range to other discerning
users requiring true UHV performance.
Full CNC manufacture for accuracy and repeatability
Formed knife edging for reliable seals.
Manufactured from 316L stainless steel to reduce
porosity
Cleaned and packed to UHV standards.
