Taco Flange Kit 3/4 NPT

This Taco 110-251SF-1 flange kit includes two stainless-steel flanges sized for 3/4 inch NPT connections. It fits Taco Series 110 and 2400 in-line circulating pumps such as models 110-113, 2400-10-3P, 2400-20-3P, 2400-45 and 2400-50-3P.

For potable-water pump installations

Installers joining a 3/4 inch NPT pipe to compatible Taco pumps will find the correct bolt-hole spacing and two-hole pattern here. Builders needing a different pipe size, a different bolt-hole diameter or a flange for another pump brand should look at other parts.

Two-hole 0.25 inch bolt pattern

Each flange has two mounting holes with a 0.25 inch diameter, matching the specified bolt-hole size for the listed Taco series. Verifying this hole size against the pump flange ensures the kit will bolt up correctly.
