Anvil 1-1/2" Floor Flange

This Anvil floor flange connects 1-1/2 inch nominal pipe to a flat surface using a flanged FNPT design. The malleable iron body carries a Class 150 rating and is explicitly marked not for pressure service. Four bolt holes provide secure mounting for drainage installations.

Drainage installers needing a non-pressure flange

Plumbers working on gravity-fed drain lines will find the Class 150 rating and malleable iron construction suitable. Installers requiring a pressure-rated fitting for supply lines or pressurised systems must select a different component rated for that duty.

Class 150 drainage capacity

The flange handles standard gravity drainage flows through 1-1/2 inch pipe without restriction. It runs out of headroom the moment any positive pressure is applied, as the manufacturer specifies it is not for pressure service and provides no pressure rating.

Questions about this item

What size threaded pipe fits the 1-1/2 inch FNPT connection on this floor flange?

A 1-1/2 inch nominal pipe with male NPT threads will thread directly into the flange opening.

Can this Class 150 malleable iron flange handle pressure from a supply line?

No, the manufacturer specifies it is not for pressure service and should only be used for drainage or vent applications.

How do I confirm the flange is seated correctly after bolting it down?

The face should sit flush against the floor with all four bolt holes aligned and the threaded opening centred over the drain pipe.
