PK-mol-KF Adaptor Kits
for molbloc-S®
Instruction Sheet
25 mm ISO-KF Style Kits Include:
These adaptor kits allow the conversion of the
molbloc-S ISO-KF style flange to various common
types of fittings. The molbloc-S elements with the 48
mm square bodies have 16 mm ISO-KF style vacuum
flange outlet fittings. The Downstream Tee Assembly
(PN 401884) end fitting, and the molbloc-S elements
with the 80 mm square body utilize the 25 mm ISO-KF
style vacuum flange fitting. The outlet of the molbloc-
S elements with the 80 mm square body utilizes the
40 mm ISO-KF style vacuum flange. These fittings
can be converted to Swagelok tube fitting, VCR®face
seal, male NPT or female NPT fittings using one of the
following adaptor kits.

In addition to these adaptors, the 40 mm ISO-KF kits
include:
QTY PART NO. DESCRIPTION

1 103309 40 mm ISO-KF Overpressure ring
1 103246 40 mm ISO-KF Clamp
CONNECTING, DISCONNECTING AND
MOUNTING MOLBLOC-S COMPONENTS
WITH ISO-KF STYLE VACUUM FLANGE
ISO-KF Style Vacuum Flange Fittings
The outlet connection system on the molbloc-S body
is the ISO-KF style vacuum flange. It utilizes an
internal centering ring, an external overpressure ring
and clamp. The seal is effected by the uniform
application of pressure by the clamp on the 15°
surface of the mating stainless steel flanges. These
mating flange surfaces compress a Viton®O-ring that
is held in place by the centering ring. The
overpressure ring keeps the O-ring in place, and
maintains a leak free connection when the system is
subjected to internal pressures above vacuum level.
This connection is reusable, rotatable, and can operate
leak free in vacuum applications up to 10-8 Torr, and in
positive pressures of 700 kPa (100 psig).
When performing a leak test of a plumbing system
that contains the ISO-KF Style Vacuum Flanges, do
not exceed the maximum operating pressure of the
molbox: 600 kPa (87 psia) for molbox A700k; 250
kPa (36 psia) for molbox A350K.
Making and Breaking Procedure for molbloc-S
ISO-KF Vacuum Flange Connection
Place the overpressure ring past one of the
ISO-KF flanges to be mated.
Place the centering ring into the groove of the
ISO-KF flange on the outlet of the molbloc-S.
Align the mating flange against molbloc’s ISO-KF
flange, and close the gap by hand.
Hold the flanges together and move the
overpressure ring directly over the mated flanges.
Place the clamp around the mated flanges.
Swing the clamp closed. If necessary loosen the
thumbscrew to allow the thrust washer and wing nut
to fall into position on top of the clamp. Fully tighten
the wing nut by hand.
To break the fitting, hold the molbloc-S with your
hand and loosen the wing nut until the clamp can
be separated. Remove the clamp, centering ring,
and overpressure ring.
Never use wrenches to hold the molbloc-S body,
or to tighten the clamp.
