Product Description
The FERNCO 1002-44 is a 4-inch flexible PVC clamp coupling designed to create leak-proof connections between sections of pipe in drain, waste, and vent (DWV) systems. The shear-ring clamp design compresses the elastomeric sleeve against both pipe ends, sealing the joint without adhesives or special tools. The flexible sleeve accommodates minor misalignment and pipe irregularities that would cause rigid couplings to fail. Licensed plumbers and drain technicians reach for this coupling when joining dissimilar pipe materials or making field repairs where perfect pipe alignment is not guaranteed. The part number, size, and compatible pipe material are molded directly into the coupling for fast identification on the job.
The 1002-44 is suited for residential and light commercial plumbing applications involving 4-inch DWV piping. Common install scenarios include joining cast iron to PVC, ABS to clay, or PVC to clay in sewer and drain lines. It performs in both above-ground and below-grade installations where ground movement or vibration makes a rigid joint impractical. Repair contractors frequently use this coupling to section out a damaged pipe run without disturbing the surrounding structure.
Key Features
- Flexible elastomeric sleeve seals across minor misalignment and out-of-round pipe ends
- Stainless steel clamps provide consistent clamping force around the full circumference
- Connects dissimilar pipe materials including cast iron, PVC, ABS, and clay
- Part number, size, and pipe material clearly marked on the coupling body
- No solvent cement, open flame, or special tooling required for installation
Compatibility
Designed as an OEM-style flexible coupling for 4-inch DWV pipe connections involving compatible pipe materials as marked on the coupling body.
Installation Notes
Installation is performed by licensed plumbers following applicable IPC and local plumbing code requirements. Shut off flow and drain the line before cutting out the damaged section and fitting the coupling. Slide the coupling sleeve over both pipe ends, ensure the pipe ends are clean and fully seated to the center stop, then tighten the stainless steel clamp bands evenly with a screwdriver or nut driver. Do not overtighten the clamps, as excess torque can distort the sleeve and compromise the seal.
