Plumbing Flange 1 1/2 NPT

This cast-iron flange connects 1 1/2 NPT piping in drainage systems. It suits installers and maintenance teams working on commercial or residential waste lines. The two-piece pack provides a spare or allows dual-point installation without separate orders.

Two-Piece Pack Convenience

Supplying two flanges in one package reduces the need for repeat purchasing on multi-branch jobs. Installers can fit both ends of a trap assembly or keep one unit as an on-site spare. The bundle simplifies inventory for plumbing contractors handling routine drain work.

Cast Iron Durability

The cast-iron body resists corrosion and mechanical stress inside drain networks. NPT threads create a tapered seal when tightened with pipe dope or tape, supporting leak-free joints. The material withstands thermal cycling from hot waste discharge without deformation.

Questions about this item

How often will the cast iron flanges need replacement in a typical plumbing system?

Cast iron flanges generally last decades; inspect the joint during routine drain maintenance and replace only if corrosion or cracking appears.

What is the first limitation when these flanges handle continuous high-volume drainage?

The 1 1/2 NPT thread size sets the flow capacity; sustained volumes beyond that rating will back up before the cast iron body yields.

Do the flanges transmit vibration or heat when the drain runs all day?

Cast iron dampens vibration and resists heat from normal waste water; no measurable noise or temperature rise occurs at the flange joint.
