ZM 4″ Flexible Rubber Pipe Coupling – Stainless Clamps

Upgrade your plumbing projects with the ZM 4″ Flexible Rubber Coupling, the go-to solution for secure, leak-proof connections between pipes of varying sizes and materials. Whether you're a licensed plumber or a DIY homeowner, this heavy-duty coupling simplifies installations while ensuring long-term reliability in even the toughest environments.

Engineered for universal compatibility, this coupling bridges gaps between cast iron, PVC, ABS, copper, and steel pipes—ideal for residential, commercial, or municipal DWV (Drain, Waste, Vent) systems. The 304-series stainless steel clamps deliver corrosion resistance and consistent clamping pressure, while the high-quality elastomeric PVC sleeve absorbs vibration, compensates for misalignment, and resists UV exposure, chemicals, and fungus. Installation is a breeze: no solvents, glues, or special tools required—just tighten the clamps with a screwdriver for a 100% watertight and airtight seal that blocks leaks, odors, and root intrusion.
