Fernco Inc P1055-44 Flexible Pipe Coupling 4 Inches

Product Description

The FERNCO INC P1055-44 is a 4-inch flexible pipe coupling designed to connect asbestos cement or ductile iron pipe to Transite pipe. Flexible couplings of this type use a shear-ring and band-clamp design to create a watertight, pressure-rated mechanical joint without requiring solvent welding, threading, or hot work. The P1055-44 accommodates minor misalignment and slight pipe movement, making it a practical solution for repair and retrofit work in buried or above-grade drain, waste, and vent systems. Licensed plumbers and pipefitters are the primary installers for this product type.

This coupling is suited for residential and commercial plumbing applications where older Transite or asbestos cement pipe meets ductile iron pipe — a common scenario in aging infrastructure repairs, sewer lateral replacements, and drain system upgrades. The 4-inch by 4-inch nominal size fits standard 4-inch pipe outside diameters on both ends. It is sold individually (each) with a package quantity of 20 units per case.

Key Features

• Connects asbestos cement or ductile iron pipe to Transite pipe in a single coupling
• 4-inch by 4-inch nominal pipe size on both ends
• Flexible construction accommodates minor angular misalignment and ground movement
• No soldering, threading, or hot work required for installation
• Sold as individual units; packaged 20 per case

Compatibility

Designed for use with 4-inch asbestos cement pipe, 4-inch ductile iron pipe, and 4-inch Transite pipe as stated by the manufacturer. Verify actual pipe outside diameters before installation to confirm fitment.

Installation Notes

Installation is typically performed by a licensed plumber in accordance with the International Plumbing Code (IPC) and applicable local amendments. Shut off flow and relieve any pressure in the line before cutting or disturbing existing pipe. Clean pipe ends of dirt, debris, and burrs to ensure proper seating of the coupling sleeve. Tighten band clamps evenly and to the torque range specified on the coupling packaging or manufacturer installation sheet — do not over-torque, as this can distort the sleeve.
