Fernco 3000-22 Proflex Neoprene Shielded Coupling 2 in

Product Description

The FERNCO 3000-22 Proflex is a 2-inch neoprene shielded coupling designed for fast, reliable connections in drain, waste, and vent (DWV) piping systems. The flexible neoprene sleeve compresses under stainless steel shielding to create a secure, leak-resistant joint without the need for soldering, threading, or cement. This coupling is rated for above-ground applications only and is commonly installed by licensed plumbers during new construction, renovation, or repair work on DWV systems.

This coupling is suited for residential and light commercial plumbing applications where a quick mechanical connection is needed between pipe ends. It works across multiple pipe materials, making it a practical solution when connecting dissimilar pipe types within the same DWV run. Above-ground interior plumbing is the intended install environment. It is not rated for buried or below-slab use.

Key Features

• 2-inch nominal pipe size fits standard DWV pipe dimensions
• Neoprene sleeve provides flexibility and a compression seal
• Stainless steel shielding band reinforces the connection and resists corrosion
• Compatible with cast iron, plastic, steel, and copper pipe materials
• Above-ground rated — no soldering, threading, or cement required
• Quick installation reduces labor time on DWV repairs and tie-ins

Compatibility

Designed for use with cast-iron, plastic, steel, and copper drain, waste, and vent pipe systems at 2-inch nominal size. Rated for above-ground use applications only. Also referenced as a replacement for Mission CP200 and cross-referenced as DXSB156-22.

Installation Notes

Installation is performed by a licensed plumber following applicable IPC or local plumbing code requirements. Ensure both pipe ends are clean, deburred, and free of debris before seating the coupling. This coupling is approved for above-ground use only — do not use in underground, below-slab, or buried installations. Tighten the shielding band clamps evenly to the manufacturer torque specification indicated on the product packaging.
