Aftermarket GRACO® 215964 Pump Repair Kit with Polyethylene Packings (Non-OEM)

Manufacturer: Total Finishing Supplies

Part Number: 647892

Comparable OEM Part Number: 215964

Description: Total Finishing's part # 20-1470 is a direct-fit replacement pump repair kit for the 1:1 Metric Fast-Flo polyethylene proportioner, engineered for contractors and technicians who depend on consistent fluid ratio mixing in high-volume spray applications.

The 1:1 Metric Fast-Flo proportioner delivers equal parts of two fluids simultaneously, making it essential for spray foam, polyurethane coatings, and dual-component epoxy systems. This kit restores internal pump function when wear or seal degradation compromises flow accuracy or causes leakage. Pump rebuild specialists and professional painting contractors rely on complete kits like this to return equipment to OEM performance without replacing the entire proportioner assembly.

Common reasons for replacement:

• Worn internal packings or seals causing fluid weeping at connection points or internal leakage between pump chambers
• Loss of proportioning accuracy, indicated by uneven mixing ratios or inconsistent spray pattern
• Polyethylene pump body becoming brittle or cracked from extended UV exposure or solvent exposure
• Check ball or valve seat degradation reducing pump pressure or preventing proper fluid shutoff

Manufactured to OEM-equivalent dimensions for proper fit and performance. Compatible Graco equipment models are listed in the Compatible Equipment section below, where available.
