Manufacturer: Total Finishing Supplies

Part Number: 503004

Comparable OEM Part Number: 277364

Description: Total Finishing's part # 20-2865 is a direct-fit replacement for Graco 277364, a gasket kit engineered for airless spray pump rebuilds and fluid system maintenance. Pump rebuild technicians and spray equipment service staff rely on gasket kits during overhauls to restore pressure integrity and prevent fluid leakage across pump head interfaces, manifold connections, and fluid pathways.

Gasket kits are critical consumables in professional pump service. Once a pump is disassembled for inspection or seal replacement, original gaskets lose their compression set and cannot be reused reliably. This kit provides the gasket materials necessary to reassemble equipment to factory performance standards without cross-threading fasteners or creating weak sealing points.

Common reasons for replacement:

• Fluid seepage around pump head or manifold connections during operation or idle periods
• Visible deterioration, hardening, or cracking of gasket material during routine inspections
• Scheduled replacement during pump rebuilds or preventive maintenance service cycles
• Pressure loss or inconsistent spray patterns traced to internal fluid bypass

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