Vacuum Fittings in General
Edwards vacuum fittings are designed to be leak-tight in vacuum
applications. However, they are not intended to provide full structural
support. When designing vacuum systems, it is essential that
consideration be given to the static and dynamic loads imposed on
each connection. If necessary, additional mechanical support should
Regular inspection including leak-checking and, where appropriate,
periodic replacement of components should be considered.
These accessories are primarily designed for vacuum applications
however some will withstand a small over-pressure, which is
indicated in the tables below where appropriate. For the purpose of
the European Union's Pressure Equipment Directive (97/23/EC),
these items are considered to be piping for Group 2 gases (i.e. gas
mixtures which are not explosive, flammable, toxic or oxidising) and
are manufactured according to sound engineering practice as defined
within the Directive.
NW and ISO Flange Fittings
Choose the optimum material to match your application and budget.
Aluminium is ideal for achieving dependable cost-effective
performance down to 10-7 mbar. Edwards also offers 316L/DIN
1.4404 stainless steel fittings for rugged corrosion resistance in
semiconductor processing and excellent repeatability in high vacuum
applications. In addition, careful quality control of elastomer
specifications ensures critical sealing materials deliver the low
outgassing performance your vacuum system performance depends
on. Edwards attention to detail on all specifications delivers fit-andforget
dependability for your vacuum equipment.
