Trykluft-kobling DN 5,5

Compressed air coupling DN 5.5 is a quick coupling solution for light pneumatic installations and industrial tools. DN 5.5 (Diameter Nominal 5.5 mm) indicates the coupling flow size - a standard for compressed air tools in the 8-12 bar working pressure range. The construction allows quick coupling/uncoupling with a simple push-fit or screw mechanism.

Frequently asked questions

What is DN 5.5?

DN (Diameter Nominal) is a European standard for coupling flow size. DN 5.5 indicates a flow passage of 5.5 mm - suitable for light pneumatic tools and air impulse applications. Larger alternatives are DN 7.2 (5204) for heavier tools.

DN 5.5 or DN 7.2?

DN 5.5 for light tools (industrial screwdrivers, small grinders). DN 7.2 for heavier tools (impact drills, large grinders). Cross-check your tool catalogue before ordering.
