Harder & Steenbeck Airbrush Spare Part
0.45mm Fineline Aircap with Seal & Needle Cap (712394)
This 0.45mm Fineline Aircap set from Harder & Steenbeck is designed to deliver controlled, consistent spray performance while allowing slightly broader coverage than finer setups. Supplied complete with seal and needle cap, it is suitable as a replacement part or as an upgrade for users seeking balanced precision and paint flow.
The fineline configuration focuses airflow cleanly around the needle, improving atomisation and helping maintain a smooth spray pattern. The 0.45mm size is particularly well suited to basecoats, primers, varnishes, and controlled detail work where you need both coverage and accuracy.
