Graco 117828 Sprayer Packing O-ring

The Graco 117828 Sprayer Packing O-ring fits within the fluid-section sealing arrangement, enabling it to maintain the intended barrier around pump components as the coating passes through the sprayer.

This part corrects the following symptoms:

• Fluid seepage near the O-ring seating area.

• Pressure variation during paint application.

• Irregular coating delivery through the pump.

• O-ring movement from its seating position.

• Coating residue collecting around the seal area.
