The Taco 953-1549-3BRP seal kit is a direct-fit “Type E / E-Design” replacement for select Taco centrifugal pumps.

Which kit do I need?
Most HVAC and hydronic circulation systems take the Standard Kit. Step up to an Upgrade Kit if your system runs hotter, carries glycol or chemicals, or handles gritty water.
| Kit | Max °F | Choose This If |
|---|---|---|
| Standard – Carbon/Ceramic/Nitrile | 200°F | Clean water at neutral pH — ordinary HVAC and hydronic circulation. This is the standard build. |
| Upgrade – Carbon/Ceramic/Viton | 450°F | Your system runs hot, or carries glycol, bleach or other chemicals that break down standard Nitrile. |
| Upgrade – Silicon Carbide/Viton | 450°F | Gritty or dirty water, wastewater and slurry, or any duty where seals keep wearing out early. Hardest faces we offer. |
