ABS Coupling 1½in Black

The ABS Coupling 1½ in Black is a straight-through coupling fitting made from durable ABS, designed to join two segments of ABS DWV (Drain, Waste & Vent) pipe of the same nominal diameter. It is ideal for creating continuous waste or vent runs in sanitary drain, sewer, or storm drainage systems. With its hub-to-hub configuration and corrosion-resistant ABS construction, this coupling is lightweight, easy to install, and built for reliable long-term service in non-pressurized drainage systems. Its design meets common plumbing standards for DWV installations, providing a code-compliant solution for residential and commercial drainage projects.

• Constructed from black ABS (Acrylonitrile-Butadiene-Styrene
