Apollo 7700 Stainless Steel Fluid Needles

Apollo Stainless Steel Fluid Needles

Fluid needles control the stroke and seal inside your 7700 gun, and they must always match the nozzle size you're using. If your gun is leaking, pulsing, or not feeding smoothly, the needle is often the part that needs attention.

Not Sure Which Needle to Choose?

• Ultra-thin dyes & toners → 0.5mm
