ISO Tapered chain clamps (HT)
EVAC ISO Tapered™ chain clamps NW 80...250.
Chain clamps available in different materials.

Composite/stainless steel: strong enough to make a good seal, but also soft enough not to crack the glass flanges under temperature changes. Usable with polymer seals only. Work with glass and metal flanges.

Alu/stainless steel or pure stainless steel: applicable for metal seals, providing sufficiently strong and uniform pressure over the flange diameter. Stainless steel chainclamps are imperative for metal seals and pressure applications.
