Fernco Inc P3001-44 Shielded Coupling 4 Inches

Product Description

The FERNCO INC P3001-44 is a 4-inch shielded pipe coupling designed to join dissimilar pipe materials in demanding drain, waste, and vent applications. It connects cast iron, plastic, or steel pipe to 4-inch copper pipe using a flexible elastomeric sleeve secured by a stainless steel shield and band clamps. The shielded design provides superior resistance to heavy earth loads and shear forces compared to standard flexible couplings. Plumbers and drain contractors install this fitting where soil movement, backfill pressure, or pipe misalignment is a concern. The coupling weighs 16.8 pounds per package unit and is sold individually.

This coupling is suited for residential and commercial underground or in-wall plumbing transitions where cast iron meets copper, plastic meets copper, or steel meets copper at 4-inch nominal pipe diameter. Typical applications include sewer lateral repairs, building drain tie-ins, and service upgrades where existing cast iron drain lines are extended with copper or plastic pipe. The Proflex shielded series is engineered specifically for high-stress burial environments where standard no-hub couplings may not provide sufficient mechanical strength.

Key Features

• Connects cast iron, plastic, or steel pipe to 4-inch copper pipe
• Shielded construction resists heavy earth loads and shear forces
• Improves pipe alignment at dissimilar-material transitions
• Stainless steel shield and band clamps provide a secure, leak-resistant connection
• Flexible elastomeric sleeve accommodates minor angular misalignment

Compatibility

Designed for 4-inch nominal pipe transitions involving cast iron, plastic, or steel pipe connecting to 4-inch copper pipe. Suitable for use in drain, waste, and vent systems where dissimilar pipe materials meet.

Installation Notes

Installation is performed by licensed plumbers in accordance with local plumbing codes and the International Plumbing Code (IPC). Shut off flow and relieve any system pressure before cutting into an existing line. Pipe ends should be clean, deburred, and free of debris before seating the elastomeric sleeve. Do not overtighten band clamps beyond the manufacturer torque specification listed on the coupling packaging.
