PVC Closet Flange for Schedule 40 Drain Lines

This white PVC closet flange connects a 4 inch nominal pipe to a 3 inch hub for residential drain installations. The flat design sits flush against the floor and meets Schedule 40 specifications for standard plumbing systems. Six bolt holes secure the flange to the subfloor during toilet mounting.

Suited for New or Replacement Toilet Installations

Builders and plumbers fitting a standard closet bend will find the socket hub and 7 inch outside diameter compatible with common floor layouts. The 140 degree Fahrenheit temperature rating covers typical residential waste lines. Projects requiring a deeper spigot, an offset pattern or a metal reinforcement ring should select a different model.

Withstands Continuous Hot Waste Flow

Schedule 40 PVC construction maintains shape under sustained discharge temperatures up to the rated limit without softening. The 1/4 inch flange thickness resists cracking when anchor bolts are torqued to specification. Long-term exposure to standard household chemicals does not degrade the socket seal.

Questions about this item

What size Schedule 40 PVC pipe does this closet flange connect to?

The hub accepts 3 inch and 4 inch nominal Schedule 40 PVC pipe for a solvent-weld socket connection.

Can this flange be used with an existing cast-iron drain line?

No, the socket is designed only for Schedule 40 PVC pipe; a different transition fitting would be required for cast iron.

How do I verify the flange is seated correctly after solvent welding?

The top face should sit flat on the finished floor with the six bolt holes aligned for the toilet bolts.
