It fits the GMax II 7900, TexSpray Mark X, TexSpray 7900HD, and GH 200 (electric) variants listed above. Always verify your exact model number and pump family before purchase.

A worn sleeve can cause internal bypass, pressure drop, and accelerated packing wear. Replacing it restores the fluid section’s sealing surface, improving pressure stability and spray consistency.

Inspect the piston rod and packing kit. If they’re worn or scored, replace them together to avoid rework and to maximize service life.

Fully depressurize and flush the sprayer. Work clean, follow Graco torque specs, and lubricate seals as directed in the service manual. Re-prime and leak-check before spraying.
