BARTSHARP Airbrush Teflon Needle Packing Bush
Replacement Teflon Needle Packing Bush
An airbrush needle packing bush is a large Teflon o ring through which the airbrush needle passes.
It is located behind the paint entry channel and stops the paint medium from travelling back along the needle to the rear of the airbrush and air valve.
If the needle packing bush is damaged, or worn, paint will bypass it, travel back along the needle and cause contamination of your air supply and leak out of the airbrush handle area.
The needle packing bush is made from highly impervious PTFE and will resist the effects of solvent based paints.
Two Teflon o rings are included in your purchase.
