Anvil 311106009 2" FNPT Galvanized Floor Flange Coupling

2-Inch Galvanized Floor Flange

This Anvil floor flange provides a rigid mounting point for 2-inch NPT threaded pipe in residential and light commercial plumbing. The ductile iron body is hot-dip galvanized for corrosion resistance in damp environments. It suits installers who need a flat, bolt-down connection to wood or concrete surfaces. The Class 150 rating defines its mechanical envelope.

Class 150 Ductile Iron Capacity

The fitting handles saturated steam up to 150 psi and meets ASTM A536 material requirements for structural integrity. It is explicitly marked not for pressure service, so it must not be used in pressurised water or gas lines. The four-hole bolt pattern distributes load evenly across the 5 1/2-inch diameter body. Headroom ends where pressure service begins.

FNPT Threaded Connection Limits

The female National Pipe Thread accepts standard 2-inch male pipe threads without proprietary adapters. Galvanized ductile iron threads resist rounding but can seize if assembled without appropriate sealant or lubricant. The flanged design fixes orientation, so final alignment depends on accurate pipe length. No pressure-rated gasket surface is provided.
