Fernco Inc P3001-33 Shielded Coupling 3 Inches

Product Description

The FERNCO INC P3001-33 is a 3-inch shielded pipe coupling designed to join dissimilar pipe materials in drainage and plumbing systems. Built under the Proflex Specialty Coupling line, it connects cast iron, plastic, or steel pipe to 3-inch copper pipe. The shielded construction adds structural reinforcement that resists heavy earth loads and shear forces, making it suitable for buried or in-slab installations where standard couplings may not hold up. Licensed plumbers and pipefitters typically install this fitting during new construction or repair work on drain, waste, and vent systems.

This coupling is used in residential and light commercial plumbing applications where pipes of different materials meet at a transition point. It is particularly well-suited for underground or below-slab drain line repairs where soil movement, settlement, or shear stress can place lateral force on pipe joints. The design also improves pipe alignment at the connection, reducing stress concentrations that can lead to joint failure over time.

Key Features

• Connects cast iron, plastic, or steel pipe to 3-inch copper pipe
• Shielded design resists heavy earth loads and shear forces
• Improves pipe alignment at the transition joint
• Suitable for buried and below-slab installations
• Proflex Specialty Coupling construction for demanding applications

Compatibility

Designed for transitions between cast iron, plastic, or steel pipe and 3-inch copper pipe in drain, waste, and vent plumbing systems.

Installation Notes

Installation should be performed by a licensed plumber in accordance with applicable local plumbing codes and the International Plumbing Code (IPC). Shut off water flow and relieve any system pressure before cutting into an existing drain line. Ensure pipe ends are clean, free of burrs, and properly aligned before tightening the shielded coupling clamps. Do not overtighten stainless clamps on fragile pipe materials such as older cast iron without inspecting pipe condition first.
