Gaahleri Fine Line Air Cap (40904) – Genuine Airbrush Spare

The Fine Line air cap, code 40904, is a genuine Gaahleri part that fits four of his airbrushes: the GHPM-Mobius, the GHAC-98D, and both the GHAD-39 and GHAD-68. Unlike a closed cap, it is an open crown design: a faceted ring at the base with two tall prongs rising on either side, leaving the front of the airbrush open between them. Gaahleri names it for fine line work and publishes nothing further about it, so this page sticks to what the product card shows. It fits in place of the air cap currently on any of those four airbrushes, which makes it a handy part to keep in the kit box. Open two-prong crown on a faceted base Named by Gaahleri for fine line work Swaps with the air cap already on the airbrush Genuine Gaahleri spare, sold singly
