Taco Flange Kit for 1-1/2 NPT Piping

This stainless steel flange kit connects 1-1/2 inch NPT piping to compatible Taco in-line circulating pumps. The package contains two standard flanges designed for potable water systems. Each flange features two mounting holes with a 0.25 inch bolt hole size.

Two-Hole Pattern Limits Alignment Options

The flange uses a fixed two-hole bolt pattern with 0.25 inch clearance. This pattern restricts rotational positioning during installation compared to four-hole designs. The FNPT connection type requires male NPT threads on the mating pipe or pump flange. No gasket or sealant is included with the kit.

1-1/2 Inch NPT Size Determines Fit

The compatible pipe size of 1-1/2 inches NPT is the critical specification. Buyers must verify their pump or piping matches this exact nominal size and thread standard. The kit fits Taco Series 110 and 2400 pump models including 0012-SF4, 2400-30S-3P and 2400-40S-3P.

Questions about this item

Which flange kit matches a 1-1/2 inch NPT pipe?

The 194-1542SF-1 kit is built for 1-1/2 inch FNPT pipe connections and includes two stainless steel flanges.

What does the 0.25 inch bolt hole size mean for installation?

Each flange has two mounting holes drilled to 0.25 inch diameter, so standard quarter-inch bolts or studs will fit directly.

How does the FNPT connection type limit the piping options?

FNPT means female National Pipe Taper threads; the flange only accepts male NPT pipe ends, not socket-weld, compression or other joint styles.
