KF 63 Flanges
KF-63 flanges can be used with EVAC chain clamps to form elastomer or aluminum metal seals. Elastomer seals are formed with ISO-63 centering ring/O-ring assemblies and elastomer EVAC chain clamps. Metal seals are formed with EVAC aluminum seals and metal seal chain clamps. KF-63 flanges are made from 304 stainless steel for 2.5 inch OD tube size.
