Taco 862-172BRP Water Seal Kit Bb Bm Cc Sb Series

Product Description

The TACO 862-172BRP is a standard B-design replacement water seal kit for base-mounted centrifugal pumps. The seal kit restores the mechanical shaft seal, preventing water leakage between the pump housing and the motor shaft. It is designed for use in hydronic heating, cooling, and general water circulation systems where Taco base-mounted pumps are installed. Licensed plumbers and HVAC technicians performing pump maintenance or seal replacement are the primary installers. The kit measures 0.98 inches by 2.01 inches by 2.99 inches overall.

This seal kit is suited for residential and light commercial hydronic systems. It fits Taco BB, CC, SB, and BM series base-mounted pumps, including the BB3010, BB4008, and BB5010 models. It is the correct OEM-style replacement when a pump exhibits shaft seal weeping or active leakage, making it a standard service item during pump rebuilds or preventive maintenance visits.

Installation Notes

Seal kit replacement is typically performed by a licensed plumber or HVAC technician. Before servicing, shut off system power and isolate the pump using service valves to relieve system pressure and drain the pump casing. Inspect the shaft and seal seat for scoring or damage before installing the new seal, as a damaged shaft will cause premature seal failure. Follow all applicable local plumbing codes during reassembly and system restart.
