The BELL GOSSETT BG P04890A is a replacement gasket body designed for use with Bell Gossett circulator pump assemblies. This gasket provides the sealing interface at the pump body, preventing fluid leakage and maintaining system pressure integrity. It is a direct service part intended to restore pump assemblies to proper operating condition. Licensed plumbers, HVAC technicians, and hydronic system specialists install this part during pump rebuild or maintenance procedures on compatible Bell Gossett Series HV and related obsolete series circulator pumps.
This gasket body is suited for hydronic heating and cooling circulation systems found in residential and light commercial applications. It is used when servicing 1-inch and 2-inch series circulator pumps where the original body gasket has failed, degraded, or is being replaced as part of a preventive maintenance procedure. This part is referenced as a replacement for Series P4890 pump configurations.
Compatible with Bell Gossett Series HV 1-inch and 2-inch series obsolete circulator pumps. Referenced replacement for Series P4890 pump gasket applications.
Installation should be performed by a licensed plumber or qualified HVAC hydronic technician. Before replacing the gasket, shut down the circulator pump, isolate the pump from the system using service valves, and relieve any system pressure before disassembly. Ensure mating pump body surfaces are clean and free of debris or old gasket material before seating the new gasket. Follow applicable local plumbing codes and the pump manufacturer service documentation during reassembly.
