These double claw clamps are designed for ISO-K DN 63 thru 100 vacuum flanges. They are constructed from aluminum and comply with vacuum technology standards such as DIN 28404 and ISO 1609.

These clamps facilitate the quick assembly of ISO-K style fittings and can be connected in any orientation. They hook into a ridged groove on the backside of the ISO-K vacuum flange. To ensure an effective vacuum seal, a centering ring with a rubber elastomeric O-ring is necessary between the two flange faces.

These double claw clamps are commonly used in the construction of process vacuum plumbing and systems for various industrial vacuum applications. They are compatible with ISO-LF flange sizes 63, 80, and 100.
