Fernco 1056-075 3/4-in. Flexible PVC Condensate Pipe Coupling for Plastic and Copper

The Fernco 1056-075 flexible coupling provides a practical connection method for drain, waste, vent, and sewer piping systems. It eliminates the need for rigid joints when linking standard 3/4-inch nominal lines, making it a reliable solution for DIYers and plumbers repairing or installing condensate and drain setups.

Built from elastomeric polyvinyl chloride, this fitting creates a watertight seal that resists sewer gases and chemical exposure. It connects mismatched pipe types, including plastic (such as PVC, ABS, CPVC, and smooth-wall HDPE), copper, steel, and lead. The included 300 stainless steel clamps resist rust and corrosion, tightening quickly with a screwdriver, nut driver, or torque wrench.

Because it fastens with mechanical bands, you avoid the fumes, mess, and curing times associated with solvent cements and primers. The internal diameter measures 1.05 inches, allowing it to bridge pipes with outside diameters ranging from 0.80 inches to 1.10 inches.

Keep in mind that sizing is precise: this coupling is designed specifically for pipes within its 0.80 to 1.10 inch outer diameter range and will not fit larger plumbing lines. It is also designed for sewer, drain, waste, and vent setups rather than pressurized supply lines.

Verdict: The Fernco 1056-075 is a dependable choice for anyone needing a clean, tool-friendly connection between plastic, copper, or metal drain pipes. Its code certifications and chemical-resistant PVC construction make it an easy recommendation for small-diameter plumbing repairs.

• Material: Elastomeric polyvinyl chloride (PVC)
• Clamp Material: 300 stainless steel
• Internal Diameter: 1.05 inches
• Pipe Outer Diameter Range: 0.80 inches to 1.10 inches
• Compatible Piping: Plastic (PVC, ABS, CPVC, Smooth Wall HDPE), Copper, Steel, Lead
• Applications: Sewer, drain, waste, and vent (DWV) piping
• Certifications: ASTM D 5926, ASTM C 1173, CSA B602, UPC Approved
• Expected Service Life: 50 years

A great fit if you:

• Need to join two different pipe materials like plastic to copper or steel.
• Want to repair a condensate, drain, waste, or vent line without messy primers and glues.
• Are working with pipes that have an outside diameter between 0.80 and 1.10 inches.

Consider something else if you:

• Are repairing pipes with an outside diameter larger than 1.10 inches or smaller than 0.80 inches.
• Need a fitting for pressurized water supply lines rather than gravity drain or vent systems.
