M-ring seal Type ME

NBRPTFEEPDM

Product overview
The M-ring Type ME is an axial static sealing element designed for SMS clamp connections and flanges used in hygienic applications. It is supplied in food-grade elastomers and PTFE compounds suitable for contact with foodstuffs. Available compounds comply with FDA 21 CFR 177.2600 / 21 CFR 177.1550 and, depending on the material, with BfR recommendation XXI, USP Class VI and 3-A Sanitary Standards.

Fields of application

• static sealing
• dynamic sealing (limited)
• single-acting assemblies
• double-acting assemblies
• linear movements
• oscillating movements
• valve housings and sanitary fittings

Main use
Valves for the food industry and other hygienic process equipment

Materials

• Elastomers: NBR, FKM, EPDM (food-grade compounds)
• PTFE and modified PTFE compounds

Technical values

• Maximum pressure: up to 16 MPa (material dependent)
• Temperature ranges (material dependent): NBR -30°C to +80°C; FKM -20°C to +200°C; EPDM -40°C to +130°C; PTFE -200°C to +260°C
• Speed: not applicable / static use

Note
Maximum values for pressure, temperature and speed are not simultaneously applicable. Actual limits depend on material choice and process media; consult technical data for selection.
