Product identity
The Fernco 1056-44 is a flexible elastomeric PVC coupling designed to join two 4-inch plastic pipes. It serves residential and light-commercial drainage installations where a watertight, corrosion-resistant joint is required.
Practical limits
The coupling accepts pipes with an inside diameter of 4.45 inches on each side and provides an overall length of 4.20 inches. It is rated for plastic-to-plastic connections only and carries no stated pressure rating or schedule classification.
Installation notes
The flexible PVC body slides over pipe ends and seals with standard stainless-steel clamps. Leaks typically occur when clamps are not tightened evenly or when pipe ends are cut unevenly, preventing full contact inside the coupling.

Questions about this item
Should I choose the 1056-44 coupling for a 4" plastic drain line?
Yes, the 1056-44 is sized for 4" x 4" plastic-to-plastic connections and fits 4.45" inside diameters on both ends.
What does the 4.20" length mean when the coupling is installed?
The 4.20" dimension is the end-to-end installed length, so it occupies that much space between the two pipe ends.
How does the elastomeric PVC material affect the joint seal?
The flexible PVC conforms to the 4.45" pipe interiors and uses stainless steel clamps to create a watertight seal without rigid fittings.
