Seal ring D-FKM-DN125

DIN Gaskets

DIN gaskets are designed specifically for DIN fittings. The underside of the gasket is flat and butts up against the welding liner's flat face, while the top side has a rounded edge which fits nicely into the groove of the welding male. The round nut then joins the liner and male compressing the gasket creating a tight seal. Gaskets are matched to other DIN fittings based on the metric sizing (Ie: A 40mm gasket is used for any DIN fitting that is 40mm, including any Imperial (inch-based) fittings that are also listed as 40mm).
