Developed by EVAC, this system enables quick and reliable connections in seconds by tightening just one or, at most, two screws—one screw is used with elastomer seals, and two screws with aluminum edge-type seals to ensure optimal force distribution.

Compared to traditional ISO-K NW125 connections, which typically require eight clamping screws when using an elastomer seal, the EVAC ISO Tapered™ system achieves the same leakproof performance with just a single screw. This translates to significant time savings, particularly in larger factory setups.

These flanges are available in both stainless steel and glass (Duran® and quartz), making the system a logical extension of the ISO KF standard to larger diameters.
