Match your pump ratio and model (e.g., EH300, EH333, 23:1 Monark) before purchase.

After rebuild, pressure-test with compatible fluid to confirm sealing and output.

Frequently Asked Questions

Typically no. The 218135 is associated with Monark/Graco 23:1 pump families (e.g., EH300, EH333). Check your pump’s ratio tag and manual; other ratios (e.g., 30:1, 45:1) usually require different kits.

Loss of pressure/output, fluid leaks from the pump section, inconsistent spray pattern, or frequent pressure drop-offs are common signs that internal packings/seals are worn and a pump repair kit is due.

Basic hand tools usually suffice, but some pumps benefit from soft-jaw vises and seal/piston tools. Always follow the service manual for disassembly order and torque specs.

Yes—218135 is a genuine Graco OEM Pump Repair Kit, engineered for the listed pump families.

Flush with appropriate solvent, keep inlet strainers and filters clean, and store with pump fluid recommended by the manufacturer to protect new packings. Recheck fasteners after initial run-in.
