What Is the Difference Between RJT and DIN Unions?

We often get asked for an RJT DIN union. Although DIN may look similar to an RJT union, it has different specifications and the fittings cannot be used together.

 

RJT is an acronym for Ring Joint Type. RJT unions are often referred to as a standard sanitary union. They comprise of a stepped seal which leaves a small crevice where the liner and male part of the union overlap. RJT fittings are common in New Zealand and are made to suit imperial (inch) tube sizes.

 

DIN is an acronym for Deutsche Industrial Norm. Originally from Germany, the DIN union is used to connect or access pumps, machinery and processing lines. DIN fittings are common in European countries and are made to suit DN (Diameter Nominal) tube sizes.
