Introduction Of Tube Nut

Tube nuts is used for pushing the cutting ring bite into hydraulic tube, connecting the adapter fittings, it has different symbols such as ISO “N”, Parker “M”, Winner”NL/NS” etc, it is also coupling nuts and union nut.. We also provide wire nut and customized nut for your different need.

Assembly Of Tube Nut

The nut for pushing the front and second (two)edge to cut(double bite) the designed depth into the tube, with the correct torque of wrench, do it in the instruction of fittings assembly.

Standards Of Tube Nut

Products meet standard of DIN 3870(LL series), DIN 2353 and ISO 8434-1.

Finish is 72 hours without surface coating corrosion acc.to ISO 9227 Fe/Zn8/Cn/T0(T2).

Design of Tube Nut

ISO 8434-1 is instead of DIN 3870 design of tube nut, nuts should be made of carbon steel, stainless steel and copper alloy, to be used with correspond to the fitting bodies.

Raw Material types of DIN tube nut

They are either cold formed, hot formed or machined from cold drawn, it is based on different size for right material shapes.
