Quick Flange Vacuum Connection
System for Rapid Assembly
and Disassembly
T
hese vacuum fittings and assemblies are an economical
system of reusable stainless steel connectors for
1

",

",
1", 1
1
/
2
", and 2" O.D. tubing. Assemblies are usable to
10
-8
torr and to a maximum temperature of 150°C. They are ideal
for vacuum systems such as mass spectrometers and scanning
electron microscopes which require rapid and frequent assembly
and disassembly. The quick flange vacuum fittings adapt to most
vacuum pumps such as Alcatel, BOC Edwards, etc.
Each vacuum seal is made by compression of an O-ring
between mating flanges. The seal is made in seconds by finger
closure of a wing-nut on a metal clamp. These modular, building
block components include all of the commonly used standard
fittings, feedthroughs, and accessories. They are available in
aluminum, brass, and stainless steel.
Quick flange assembly is simplified by the 360° rotatable
flanges and the self-centering feature of the centering ring.
Pressure is applied uniformly around the 15° outer flange surface
by finger tightening the clamp wing-nut until the first metal-to-metal
contact is made between the inner surfaces of the flanges and the
spacing lips of the centering ring. This compresses the O-ring
between the mating flanges and makes the vacuum seal.
Features of ISO-QF Components
•
Flanges are sexless, infinitely rotatable, self centering, and
most important available in a multitude of configurations offering
the user the choice of either butt welding or internal welding.
•
Components are interchangeable with all assemblies made
to standard ISO measurements.
•
Centering rings are available in 304 stainless steel, brass or
aluminum with viton or buna “O” rings.
•
QF components are made to exacting standards on
computer controlled turning lathes. Tolerances and surface
finishes are unsurpassed in the industry. Each component is
individually inspected to insure that no scratch or other defect
exists. Every component is then completely cleaned and shipped
ready for use in any application.
•
Every welded assembly is helium leak checked and certified
to have a leak rate of less than 1 x 10
-9
std cc/sec.
•
QF Aluminum & Stainless Clamps are machined from solid
aluminum bars on computer controlled lathes. Tensile strength is
much stronger and more rigid, durable clamps are the result. They
are also more symmetrical and easier to use in constricted
applications. An integral locking device is also machined into the
clamp which prevents accidental opening of the clamp on flange
assemblies when in a tightened state.
Dimensions
S.I.S.
™
offers all of our ISO configurations in the following
sizes; QF10, 16, 25, 40 and 50. The QF10 and 16 sizes are used
typically with
1
/
2
" and
3
/
4
" tubing and both utilize the same size
clamp. The QF25 is normally used with 1" O.D. tubing, the QF40
with 1
1
/
2
" O.D. tubing and QF50 with 2" O.D. tubing. Our number-
ing system reflects this situation. Where obsolete 20 and 32 size
flanges are encountered, our adaptive centering rings will enable
the user to interface with these sizes.
If you do not see the fitting you need, S.I.S. can custom
manufacture a fitting to your requirements
