DIN 11851 Adapters

DIN Male to Tri Clamp Adapter

A DIN weld male to Tri Clamp adapters greatly simplifies the transition between the European and American standard sanitary fittings. The DIN male threads conform to the European metric standard which fits the appropriately sized DIN Nuts, and the Tri Clamp is the standard US ferrule size for use with sanitary clamps.

Understanding DIN fittings

Deutsches Institut fur Normung (DIN) 11851 fittings are used extensively throughout Europe and the UK, and as such are the most common European fittings encountered in the US. A complete DIN union consists of a slotted DIN round nut, a threaded welding male, a gasket and welding liner. The welding male and welding liner are available in both Imperial and metric tube sizes, however the threads of the welding male and round nut are always measured in metric (mm) sizes.
