EVAC ISO Tapered™ connections are available in sizes NW80 up to NW250 as standard and also larger sizes up to NW700 upon request.
Developed by EVAC, this system allows customers to get a leakproof connection within seconds by tightening only one or max. two screws (one screw is being used in case of using elastomer seals and two screws in case of using aluminium edge type seals in order to get a better force distribution).
For example, in comparison with an ISO-K NW125 connection (with an elastomer seal 8 clamping screws are recommended), you can get the same connection leakproof with just only one screw in case of using the EVAC ISO Tapered™ system. The time saving factor is apparent, especially with a larger factory setup.
Flanges are available in stainless steel as well as in glass (Duran® , quartz).
This system logically expands ISO KF to the larger diameters.
