Sealing Maintenance Kit for High-Pressure Pump Systems

Compatible Machines
  • Graco airless paint sprayer pump assemblies (select models)
  • Graco fluid handling and coating systems
  • Industrial reciprocating pump units requiring B1 PT-8 sealing
  • Professional spray rigs using OEM O-ring sealing configurations

Precision O-Ring service kit designed to restore sealing performance in high-pressure Graco pump assemblies. Supports leak prevention, pressure stability, and extended equipment life in demanding spray applications.

The kit typically includes precision-grade O-rings used for sealing pump assemblies and internal fluid pathways in compatible Graco systems.

It restores sealing integrity in worn pump systems, reducing fluid leakage, pressure loss, and inconsistent spray performance.

No, compatibility depends on pump configuration and sealing system design. It is intended for specific Graco assemblies requiring B1 PT-8 O-ring specifications.

Replacement is recommended during scheduled maintenance or when signs of leakage, pressure drop, or wear are detected in the pump system.
