This listing is for a single Fernco 1056-43 flexible reducer coupling. This fitting is a standard plumbing component used to connect two pipes of different sizes in a drain, waste, or vent (DWV) system. It provides a secure, leak-proof seal on a variety of pipe materials.

Its primary function is to connect a 4-inch pipe to a 3-inch pipe. The flexible PVC construction allows for slight misalignments and absorbs vibration, while the stainless steel clamps provide a strong, lasting connection.

Key Features:

• Connection: Connects 4" pipe to 3" pipe.
• Versatile Compatibility: Designed for use with Cast Iron (CI), Plastic (PVC, ABS), Steel, Copper, or Lead pipes.
• Durable Construction: Made from tough, elastomeric polyvinyl chloride that remains flexible across a wide range of temperatures.
• Secure Clamps: Features two 300-series stainless steel worm-drive clamps that are corrosion-resistant and ideal for underground use.
• Application: Suitable for non-pressurized DWV, sewer, and drain applications.
