The water closet shall be bolted to the hanger with corrosion-resistant bolts or screws. Joints shall be sealed with an approved elastomeric gasket, flange-to-fixture connection complying with ASME A112.4.3, or an approved setting compound.

Floor flanges. Floor flanges for water closets or similar fixtures shall not

be less than 0.125 inch (3.2 mm) thick for brass, 0.25 inch (6.4 mm) thick for plastic, and 0.25 inch (6.4 mm) thick; and not less than a 2 inch (51 mm) caulking depth for cast-iron or galvanized malleable iron.
