Built from a tough neoprene sleeve paired with robust stainless steel clamps, this coupling stands up to the demands of drain-waste-vent (DWV) installations in both residential and light commercial applications.\u003c\/p\u003e \u003ch3\u003eWhat sets this No Hub Coupling apart\u003c\/h3\u003e\n\u003cul\u003e \u003cli\u003e\n\u003cstrong\u003eDual hub sizes\u003c\/strong\u003e: End 1 is 2 in., End 2 is 1-1\/2 in. hub, enabling quick transitions between common pipe sizes without extra adapters.\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eNeoprene gasket + stainless steel\u003c\/strong\u003e: A flexible, chemical-resistant seal backed by corrosion-resistant bands for long-term reliability.\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eLead-free construction\u003c\/strong\u003e: Safe for environments where lead exposure is a concern.\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eTemperature tolerance\u003c\/strong\u003e: Rated up to 220°F, suitable for drainage systems that see occasional heat from hot fluids.\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eNo hub design\u003c\/strong\u003e: A reliable alternative to cemented joints, relying on clamps to secure the sleeve around pipe ends.\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003ePackaging\u003c\/strong\u003e: Sold as a single unit in bulk packaging for quick restocking in maintenance or professional shops.\u003c\/li\u003e\n\u003c\/ul\u003e \u003ch3\u003eApplications and use cases\u003c\/h3\u003e\n\u003cp\u003eUse this coupling to repair or connect hubbed pipes in DWV runs where a quick, durable seal is required. Ideal when replacing damaged no-hub sections or joining a 2\" line to a 1-1\/2\" branch without tearing out existing piping. The neoprene\/stainless steel combination tolerates minor misalignment and compresses to form a tight seal around the pipe circumference.\u003c\/p\u003e \u003ch3\u003eInstallation tips\u003c\/h3\u003e\n\u003cul\u003e \u003cli\u003e\n\u003cstrong\u003ePrepare\u003c\/strong\u003e: Clean and deburr pipe ends so the neoprene sleeve seats evenly.\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eAlign\u003c\/strong\u003e: Position the hub ends so they sit squarely and avoid future stress on the joint.\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eTighten\u003c\/strong\u003e: Secure clamps progressively and evenly to ensure uniform compression along the gasket.\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eInspect\u003c\/strong\u003e: Check for any gaps after installation and run a small test with water to verify seal integrity.\u003c\/li\u003e\n\u003c\/ul\u003e \u003cp\u003eNote: This No Hub Coupling is not IAPMO certified and not NSF listed, with an average lead content listed as lead-free.
