Grundfos 99880042 Flange Gasket

Grundfos 99880042 Flange Gasket

For service technicians maintaining hydronic systems, the Grundfos 99880042 flange gasket is the critical seal required for high-performance UP and LAUP series circulator pumps. This 2-pack gasket set serves as the direct replacement for Grundfos 96409353, ensuring your 2-stage pump installations maintain a leak-free interface at the inlet and outlet ports. Designed for GF-50 series flanges and compatible with 2-inch flange sets 96409354 and 96409355, these gaskets are engineered to withstand the thermal stress and pressure fluctuations typical in commercial HVAC and domestic hot water applications.

Replacing worn gaskets with OEM Grundfos pump parts prevents cavitation and system pressure loss. These gaskets are frequently utilized in cast iron pump flanges and bronze pump housings, providing a precise seat that eliminates the need for messy sealants. Whether you are performing routine maintenance on a Grundfos UP pump or a complete overhaul of a LAUP model, keeping these replacement pump gaskets in your service truck ensures you can restore system integrity without unnecessary downtime.

Key Benefits
  • Precise Compatibility: Engineered specifically for Grundfos UP and LAUP series pumps for a perfect bolt-hole alignment.
  • High-Temperature Durability: Resists degradation in hydronic heating and domestic hot water recirculation systems.
  • Universal Fitment: Cross-references directly with discontinued part number 96409353 and supports GF-50 flange configurations.
  • Optimal Sealing: High-quality material prevents vacuum leaks on the suction side and pressure leaks on the discharge side.
