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.

Questions about this item

Does the flange kit include mounting bolts, or do I need to buy them separately?

It fits Taco Series 110 and 2400 pumps such as models 110-113, 2400-10-3P, 2400-20-3P, 2400-45 and 2400-50-3P.

What does the 3/4 in NPT connection mean for installation on a potable water system?
