This kit provides the sealing components needed to restore pump shaft integrity and prevent fluid leakage in centrifugal pump systems. With a 1.75-inch seal size and a Buna-N elastomer paired with a ceramic seal face, it delivers reliable chemical compatibility and wear resistance in typical hydronic and water-handling service. Licensed plumbers and pump service technicians are the primary installers of this component.\u003c\/p\u003e\n\u003cp\u003eThis seal kit is suited for pump repair and maintenance work in residential and light commercial plumbing, hydronic heating, and water circulation systems where Paco brand pumps are installed. It is used during scheduled maintenance intervals or when shaft seal failure causes visible leakage at the pump housing. Having the correct seal size and material combination is critical to achieving a leak-free repair and avoiding repeat service calls.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1.75-inch seal diameter for precise fitment in compatible Paco pump housings\u003c\/li\u003e\n  \u003cli\u003eBuna-N elastomer construction provides resistance to water and common hydronic system fluids\u003c\/li\u003e\n  \u003cli\u003eCeramic seal face offers hardness and wear resistance for extended service life\u003c\/li\u003e\n  \u003cli\u003eOEM-style replacement designed to restore original pump sealing performance\u003c\/li\u003e\n  \u003cli\u003eSupports leak-free pump operation in water circulation and hydronic applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement seal kit for Paco pump models requiring a 1.75-inch Buna-N and ceramic mechanical seal.
