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.
