زنبرك مكبس صمام الهواء (39107/39108/39109)

My old spring finally gave out mid-project, and this replacement fits the airbrush body perfectly with no wobble. The piston moves smoothly again and my paint flow is back to a steady, even line. Definitely glad I grabbed this spare.

My old spring was getting weak and causing sputtering, but this replacement brought back that consistent air flow I needed for fine lines. The metal feels sturdy and the coil tension is exactly right for my model.

This spring fit perfectly into my airbrush and immediately fixed the sticky trigger issue I'd been dealing with. The tension feels exactly right, and it was nice to have a proper replacement rather than trying to clean the old one.
