Shielded Transition Coupling

The Fernco 3001-43 is a shielded transition coupling designed to join pipes of different nominal sizes. It connects a 4 inch pipe to a 3 inch pipe using a neoprene sleeve and stainless steel shield. The coupling provides a watertight seal for drainage and waste systems.

Installers joining 4 in to 3 in pipe

This coupling suits installers who need a reliable transition between 4 inch and 3 inch nominal pipe sizes in drain applications. It is not for users joining pipes of the same diameter or those requiring a coupling for press-fit or solvent-weld connections.

Highlights

  • Shielded design protects pipe joints
  • Neoprene construction resists corrosion and wear

Questions about this item

What pipe sizes must I already have for the 3001-43 coupling to connect?

The coupling joins a 4 inch nominal pipe on one end to a 3 inch nominal pipe on the other, so both pipe sizes need to be present in your system.

Will the 3001-43 coupling fit older cast-iron or plastic drain lines of the same nominal size?

The neoprene sleeve and stainless-steel shield clamp onto any 4 inch and 3 inch nominal pipe regardless of material, so existing cast-iron, PVC or ABS lines of those sizes will work.
