Cast Iron Flange for 1 1/2 Inch Pipe

The Taco Inc 110-254F-1 flange fits 1 1/2 inch piping and suits drainage or trap installations. It is sold as a new pair for plumbers or maintenance teams needing direct replacements. Compatible with Taco Series 110 and 2400 components, it matches models such as 110-113 and 2400-10-3P. This cast iron piece is not rated for potable water systems.

FNPT Connection with Two Mounting Holes

The flange uses an FNPT thread to join the pipe and provides two bolt holes sized at .25 inch. This pattern aligns with the listed Taco models and Grainger references 5CHJ9, 5CHK1 and 5CHK7. The standard flange type ensures a straightforward mechanical joint without proprietary hardware. Builders needing a different hole count or thread style should select another part.

Cast Iron Build for Non-Potable Drainage

Cast iron construction gives the flange mechanical strength for drain and trap duty. The material handles the temperatures and mechanical loads typical in non-potable plumbing. Two mounting holes keep the installation simple but limit orientation options compared to four-hole patterns. The unit is restricted from sale in no states, so it can be shipped widely for standard drainage work.

Questions about this item

Does the cast-iron flange need any periodic replacement or maintenance?

The cast-iron construction resists corrosion and does not require scheduled replacement; inspect the two bolt holes during system service.

What limits continuous use of the 1 1/2 inch FNPT connection?

The 0.25-inch bolt holes and two-hole mounting pattern set the mechanical load limit for the flange joint.

How much heat or noise does the flange generate during all-day operation?

As a passive cast-iron component it produces no noise and adds no measurable heat to the piping system.
