The DIN Union is used to connect to or access pumps, machinery, and processing lines. They consist of four parts a male part, a weld liner, a nut and a DIN seal.
About
DIN Unions are similar to RJT Unions however RJT Unions have the stepped seal to fill the crevice. DIN Unions are most common in European countries and are made to suit Diameter Nominal tube sizes. DIN fittings are scarce in NZ and they only suit Diameter Nominal tube sizes which makes it a slight problem for us kiwis that use imperial (inch) tube as they are not suitable to fit and Diameter Nominal tube can be difficult to source.
The Metal Company found a solution to make buying stainless steel easy and developed the DIN inch male part and DIN inch weld liner which both consist of DIN Union that connects to imperial tube sizes – problem solved.

What Are DIN Inch Fittings? | Technical Tuesday
Standard DIN fittings are unable to fit suitably to imperial sizes and DN tube can be difficult to source. The Metal Company developed the DIN Inch Male Part and the DIN Inch Weld Liner which both consist of a DIN union that butt welds perfectly to imperial tube sizes. Watch Huntley discuss.
How to Identify Between DIN, RJT, BSM & SMS Unions
Sanitary unions can be hard to identify between. Let Sinead show you how to differentiate between each of the DIN, RJT, BSM and SMS unions.
What Are DIN Unions?
DIN Unions are often found in NZ on imported pumps, machinery and processing equipment and butt welds to metric tube. Be sure to check out our DIN inch range with imperial sizing to make your install easier.

Maximum Seal Temperature: +100-120°C Other Titles: Buna-N, Perbunan, Acrylonitrile Butadiene Rubber or Nitrile-Butadiene Rubber (NBR). Nitrile (NBR) is a synthetic rubber which is suitable for oils, hydrocarbon fuels, hydraulic fluids, fats and flame retardant liquids. The Metal Company use white nitrile rubber for food grade quality (FQ) flange gaskets. Blue nitrile rubber is used for standard RJT stepped seals with a maximum temperature of 100°C and DIN O-ring seals with a maximum temperature of 120°C. Black nitrile rubber is used for camlock gaskets. Nitrile is also used for black seals on Table E Lugged Butterfly Valves, with a maximum temperature of 120°C.

The RJT C Spanner is suitable for both RJT slotted nuts and DIN slotted nuts from 1” (25.4) to 4” (101.6) sizes. The C Spanner has a hooked spanner function either end of the tool and is able to tighten and release an RJT slotted nut by applying pressure in a lever action.

The DIN union is commonly used to connect or access pumps, machinery and processing lines. DIN fittings are scarce in New Zealand and Australia, generally speaking they belong to Europe. Even so, Kiwis and Aussies have been known to use DIN fittings on various contraptions like pumps, imported machines and process equipment. However DIN fittings only suit DN (Diameter Nominal) tube sizes. This becomes a problem for countries that use imperial (inch) tube because DIN fittings are unable to fit suitably to imperial sizes and DN tube can be difficult to source. For this reason, The Metal Company developed the DIN Inch Male Part and the DIN Inch Weld Liner which both consist of a DIN union that connects to imperial tube sizes. This is New Zealand and Australia’s answer to European fittings. DIN Inch fittings can be used with a standard DIN Slotted Nut and DIN Seal. Firstly, let’s explain ‘DIN’.

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.
