Us Seal TACO-953-1549-3BRP Mechanical Seal Kit Taco Pumps

Product Description

The US SEAL TACO-953-1549-3BRP is a mechanical seal kit designed as a service replacement for Taco circulation pumps used in hydronic heating systems. The kit includes a mechanical seal, a BR shaft sleeve, a casing gasket, and a sleeve gasket, providing all the components needed for a complete seal service in a single package. This type of kit is installed by licensed plumbers and HVAC technicians during pump rebuilds or when a seal failure causes leakage at the pump shaft. Having all mating components in one kit ensures proper fitment and reduces the risk of mismatched parts during service.

This seal kit is intended for hydronic heating applications where Taco pumps are used to circulate hot water through residential or light commercial systems. It is suited for pump rebuilds performed during routine maintenance or after seal wear causes system leaks. Compatible Taco pump series include the CI Series, KS Series, KV Series, and FI Series. Installers should verify the pump model and shaft size before ordering to confirm correct fitment.
