ISO-KF · VACUUM CLAMPS
ISO-KF Chain Clamp
ZEROVAC ISO-KF chain clamps join ISO-KF vacuum flanges with the correct centering ring and seal. Articulated Aluminium 6081 segments transfer the clamping load around the flange circumference, with maximum tightening torques specified by seal type.

INSTALLATION NOTE
Align the correctly sized centering ring and seal between the flanges. Position the chain clamp around the joint and tighten without exceeding the maximum torque shown for the seal in use. The clamp does not replace the vacuum seal.
