FERNCO COUPLING - 4"

Connecting 4" DWV pipe, this Fernco flexible coupling splices two 4" ends into a gasketed, watertight joint with no solvent, threads, or heat. The elastomeric sleeve slides over both pipes and stainless steel band clamps draw each side tight, joining the plastic, cast iron, steel, and copper pipe common in building drains and sewers. Its flexibility takes up misalignment and ground shift, a key reason it is trusted for below-grade repair. For a large-diameter 4" connection or repair splice, it goes together in minutes.

Key Features:

• Joins Two 4" Pipe Ends -- Splices same-size pipe in one gasketed coupling without hub fittings.
• Bridges Dissimilar Materials -- Connects plastic, cast iron, steel, and copper pipe together.
• Stainless Band Clamps -- Clamps lock each end down for a secure, watertight joint.
• Flexes with the Run -- Absorbs misalignment and ground movement in drains and sewers.
• No Solvent or Threads -- Push-on with a nut driver -- no glue, heat, or threading.

Where to Use:

• Rough plumbing -- Joining and repairing DWV, drain, and sewer pipe on new and retrofit work.
• Building maintenance -- Splicing in repairs and connecting dissimilar pipe without hub fittings.
• Drain & waste repair -- Making fast, gasketed connections in below-grade and in-wall drain lines.
