DIN 11851 Sanitary Gaskets

Gaskets

Deutsches Institut fur Normung (DIN) Fittings

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).

What type of material should I use?

While we are prohibited from recommending a gasket type, we do offer a Chemical Resistance Chart (new window) that matches the resistance level of gasket materials to the different chemicals / food products you may be using. We may suggest using an A- or B-rated gasket for your particular application.

Notice:

Incorrect sizing is common with DIN 11851 fittings. Please review our DIN 11851 Guide for assistance in sizing your DIN 11851 fitting.
