Why Choose This O-Ring Pack

Service cue: Clean grooves and install with compatible grease only if your gun manual permits it to avoid swelling or extrusion.

Typical Compatibility

  • Graco Fusion AP spray guns (piston/bulk O-ring positions identified in parts charts).
  • Fusion-family spray guns and assemblies that specify the OEM kit in the Illustrated Parts List.
  • Aftermarket listings for Graco/ASM/Airlessco referencing the same interchange.

Always confirm by your exact gun model and IPL/revision to ensure correct ring size and location.

What This Product Fits

  • Graco Fusion AP spray gun - kit shown as “O-ring piston, pkg of 6” in parts listings.
  • Fusion gun “bulk/large piston O-ring” locations called out by OEM/distributors.

Installation Notes

  1. Relieve pressure; disconnect air/fluid per your gun manual.
  2. Disassemble the Fusion gun section that houses the piston/bulk rings; note each ring’s position.
  3. Clean grooves and mating surfaces; inspect for scratches or burrs.
  4. Install new rings without twisting or over-stretching; lubricate only if allowed by OEM guidance.
  5. Reassemble and leak-check at low pressure; verify spray pattern before production use.

Tip: Replace seals in pairs/sets on both sides of the housing to keep wear and timing even.

When to Rebuild / Replace

  • Weeping at the bulk housing or piston area during recirculation or purge.
  • Frequent solvent cleanings leading to ring hardening or flattening.
  • Pattern instability traced to air ingress at fluid joints.
  • Visible cuts, swelling, or deformation on the removed rings.
