ABS Coupling 3in Black

3 ABS Coupling is a straight-through coupling fitting manufactured from durable black ABS plastic. It is designed to join two segments of ABS DWV (Drain, Waste & Vent) pipe of the same 3-inch nominal diameter, creating a continuous run for drainage and vent systems. Because it is injection-molded from corrosion-resistant ABS and can be solvent-cemented easily, the coupling is lightweight, resistant to moisture, and suitable for underground or sub-floor installations. Its simple hub-to-hub design allows quick installation even in confined spaces, while offering long-term, maintenance-free performance for non-pressurized sewer, storm, or sanitary drainage systems.

• Lightweight, corrosion-resistant, and moisture-resistant (won’t rust, pit, or degrade)
• Quick and easy installation with single-step ABS solvent cement (no specialized equipment needed)
• Durable and resilient for long-term, maintenance-free use
• Suitable for underground, sub-floor, or concealed DWV installations
  Code-compliant for typical DWV applications (sanitary, sewer, storm drainage)
• Made from high-quality black ABS (Acrylonitrile-Butadiene-Styrene) plastic
• Hub × Hub coupling — connects two pipes straight, no change in direction

• Joining two 3″ ABS DWV pipes for continuous sanitary drain lines
• Sewer and storm drainage systems in residential or commercial buildings
• Waste and vent piping networks (DWV systems)
• Underground or sub-floor drainage installations
• General non-pressurized drainage applications where a straight coupling is required

• Material: ABS plastic
• Size / Nominal Diameter: 3″ × 3″ (for 3-inch ABS DWV pipe)
• Fitting Type: Coupling (straight)
• Connection Type: Hub × Hub (solvent-weld hub connections)
• Weight: ~ 0.149 kg (≈ 0.328 lb)
• Installation Method: Single-step ABS solvent cement (single-step solvent-weld)
• Resistance: Moisture-resistant, corrosion-resistant, does not rust/pit or degrade when exposed to moisture
• Suitability: Non-pressurized drain, waste & vent (DWV) systems; underground and sub-floor applications
