Taco 110-252SF-1 Flange Kit — Pipe Size 1 in NPT

This kit contains two stainless-steel flanges designed for 1-inch NPT piping. It connects directly to compatible Taco in-line circulating pumps and drain components. The parts are new and ready for installation in potable water systems.

Critical spec: FNPT flange-to-pipe connection type

The flange uses a female National Pipe Thread (FNPT) connection for the 1-inch pipe size. This thread standard determines whether the kit matches your existing piping and pump inlet or outlet. Verify the thread type before ordering to avoid fitment issues.

Built for continuous potable-water circulation

Stainless steel construction resists corrosion during constant flow in potable systems. The two-bolt mounting pattern secures the flange to compatible pump models such as the 110-113 and 2400 series. The kit is not suited for applications requiring a different bolt-hole count or pipe diameter.

Questions about this item

How does the 1 inch NPT flange size work when installed on an in-line circulating pump?

The 1 inch FNPT connection threads directly onto compatible pump ports, creating a secure joint for potable water systems without additional adapters.

What does the FNPT connection type limit when mating this flange to pipe?

FNPT provides a tapered female thread that seals with male NPT pipe threads; it cannot join to compression, sweat or push-fit fittings without a proper transition fitting.

What physical clearance is needed to mount the two 0.25 inch bolt holes on this flange kit?

Two mounting holes sized at 0.25 inch diameter require matching bolts and enough surrounding surface to accommodate the standard flange pattern on series 110 or 2400 pump bodies.
