What happens here

Begin reassembly by first lubricating and carefully placing the smallest O-ring onto the needle in its designated flat spot. Then, lubricate the larger O-ring and slide it onto the handle piece, ensuring it sits correctly. O-ring lube helps these parts slide into place easier and maintains their seal. Make sure no dried paint remains on the O-rings or their seating areas.

Goal: Properly place and lubricate the O-rings back onto the needle and handle.

Tools and materials

  • Handle Piece Graco — The handle component of the spray gun
  • Needle Graco — The internal needle of the spray gun
  • O-ring Lube — Lubricating O-rings
