Locating ring ACR series

The KF reduction centering ring with O-ring is a sealing component designed to ensure accurate centering between two nominal-diameter (DN) flanges of different sizes and to support the O-ring for reliable sealing. The assembly consists of an AISI 304 ring and a gasket; available gasket materials are Fluoroelastomer (FKM, Viton) and Nitrile-butadiene (NBR, Buna).
