M-ring seal Type MC

elastomerNBRPTFE

Overview
The M-ring Type MC is an axial static sealing element designed for stainless steel fittings (comparable to DIN 11851) with a raised profile for hygienic applications. Common compound materials: NBR, FKM, EPDM and PTFE. Compounds are available to meet FDA requirements (21 CFR 177.2600 or 21 CFR 177.1550). Additional material options available on request (e.g. BfR recommendation XXI, USP Class VI, 3-A Sanitary Standards).
