Shielded Transition Coupling for 6-inch Pipe

The Fernco 3000-66 is a shielded transition coupling designed to join pipes with a nominal size of 6 inches. It uses a neoprene gasket housed in a corrosion-resistant shield to create a watertight seal. The coupling measures 3 inches in overall length and fits female-ended connections.

Suited for Drain Repairs and New Installations

This coupling suits plumbers and contractors joining 6-inch drain lines in residential or commercial systems. The shielded design adds stiffness for buried or exposed runs where ground movement occurs. It does not fit pipes outside the stated nominal diameter and is not intended for pressure-rated supply lines. Builders needing a different pipe size or a non-shielded flexible coupling should look at other models.
