Rupture disc KUB® CLEAN - For applications with strict hygiene requirements

KUB® clean raises the bar in the field of sanitary rupture discs: KUB® has a completely leak-tight and smooth design that guarantees perfect hygiene standards in sanitary applications. Best feature: KUB® clean is simple to install in existing tri-clamp flange systems. It complies with all hygienic design requirements and is suitable for CIP and SIP applications. The smooth surface of the sealing membrane, integrated ­gasket and direct installation into tri-clamp flange systems mean that this rupture disc has no score lines, indentations or notches on the process side, which can trap dirt or product residues during production or cleaning cycles. This makes KUB® clean ideal for use in aseptic and sanitary applications.
