Stainless Steel Vacuum CF63R /CF63 SS304 SS316L CF Flexible Bellows Flanges Tube Components

The CF flange connection consists of two identical flanges with a flat gasket made of OFHC copper,
bolts,nuts.Because  the  applications  are  UHV  environments,so  the  preparation  work  is  very
important before installation.Surface cleaning guarantees the lowest possible outgassing and leakThe CF flange connection consists of two identical flanges with a flat gasket made of OFHC copper,

important before installation.Surface cleaning guarantees the lowest possible outgassing and leak rate.

Using  clean  lint free gloves,place  pre-cleaned  OFHC  copper gasket against  knife edge seal,
preferably the flange most likely to hold and support gasket from falling.With gasket in place fit
mating flange with desired bolt orientation;if flanges are fitted with leak test grooves,they should
aligned.Using  clean  lint free gloves,place  pre-cleaned  OFHC  copper gasket against  knife edge seal,

With flanges aligned,insert proper size bolt and hand tighten.Repeat this procedure with remaining
bolts.After  hand  tightening  all  bolts,support  bolt  and  tighten  nut  using  two  closed-end  box
wrenches.(washer are used on nut side)With flanges aligned,insert proper size bolt and hand tighten.Repeat this procedure with remaining

CF flanges are suited for use in applications requiring a very clean environment,ultrahigh vacuum
conditions,high  temperature  or  where  critical  or  dangerous  materials  must  be  contained  or
excluded.
