Taco 194-1540F-1 Cast Iron Flange Pair

This two-pack supplies 1 1/4 inch FNPT flanges cast from iron for in-line circulating pump installations. Each flange carries two mounting holes drilled to 0.25 inch bolt size and matches Taco series 110 and 2400 pump models. The components are not rated for potable water systems.

Installers Servicing Taco 110 or 2400 Pumps

These flanges suit technicians replacing worn connections on compatible Taco in-line circulators where a 1 1/4 inch FNPT joint is specified. Buyers working on different pump brands, alternate pipe diameters, or potable water lines should look elsewhere because the bolt pattern and material do not transfer.

1 1/4 Inch FNPT Connection with Two Bolt Holes

The decisive specification is the 1 1/4 inch FNPT pipe thread combined with a two-hole flange drilled for 0.25 inch bolts. Only systems requiring this exact thread size and hole pattern will seal and align correctly with these cast iron parts.
