Shielded Coupling for 3-inch Pipe

This shielded coupling connects two 3-inch nominal pipes using a neoprene gasket held by a stainless-steel shield and clamps. It is built for drain, waste and vent systems where a watertight, flexible joint is required. The assembly arrives new and ready for installation without special tools.

Installers needing a code-approved transition joint

The coupling suits plumbers and contractors joining same-size pipe in gravity-flow drainage. It does not suit press-fit or solvent-weld only systems, nor applications that demand a rigid, non-flexible connection. Buyers needing a different nominal size or a non-shielded sleeve must select another model.

Nominal 3-inch by 3-inch pipe size

The single specification that decides fit is the 3-inch by 3-inch nominal pipe size marked on the body. Verify both pipe outside diameters match this rating before purchase; an incorrect diameter will prevent a proper seal.

Questions about this item

Will the 3001-33 coupling fit the 3-inch cast-iron drain line I already have in place?

The shielded coupling is built for a nominal 3-inch pipe size on both ends, so it will join directly to your existing 3-inch line without adapters.

How can I confirm the 3001-33 is sealed correctly once I tighten the clamps?

After tightening the stainless-steel bands to the recommended torque, run water through the joint and watch for any drips; a dry joint means the neoprene gasket is seated properly.

Does the 3001-33 package include the stainless-steel clamps, or do I need to buy them separately?

The coupling ships with its integral shield and clamps already assembled, so nothing extra is required for installation.
