NIBCO 3″ 90 Degree ABS Elbow (U58073)
NIBCO’s 3″ 90-degree elbow provides a reliable angle to connect two pipes or fittings, with hub ends designed for quick connection to male unthreaded pipes. Its ABS-DWV compatibility offers resistance to chemicals and corrosion, making it suitable for drainage and venting in varied temperature conditions. The elbow’s light weight supports fast assembly in tight spaces and reduces installation effort on mid-sized projects.
Charlotte Pipe 3″ DWV Coupling
This 3″ DWV (Drain, Waste and Vent) coupling from Charlotte Pipe is designed for sanitary drain systems where pressure is not a factor. The black ABS fittings are ideal for DWV applications and are suitable for systems that operate below 140°F. It is not intended for pressurized lines, but it provides a durable, corrosion-resistant solution for residential and light commercial drainage networks.
Supply Giant 3″ Flexible PVC Coupling with Clamps
This flexible coupling is designed for 3″ nominal pipes and offers compatibility with cast iron, plastic, copper, lead, and steel piping. It provides a leak-proof, rot-proof seal and is suitable for non-pressurized DWV drainage and vent systems both indoors and outdoors. The flexibility can help accommodate minor misalignments and reduce the risk of joint stress in complex runs.
Supply Giant 3″ Black Nipple
This black steel nipple is a close, 3″ nominal pipe diameter with male threaded ends. It complements black ABS/ PVC drainage and vent assemblies in situations where a black, threaded connection is required. While not a PVC pipe, the nipple is often used to bridge metal and PVC components in durable, mixed-material drainage setups. verify compatibility with your system’s threading standards before use.
Landical 2-Pack 3″ ABS Drain Pipe
Landical offers two 3″ ABS drain pipes in a compact 2-foot length for quick drainage setups. The ABS material provides durability and resistance to chemical exposure, with an inner and outer dimension designed for straightforward installation. This option is well-suited for short runs, repairs, or extending an existing DWV network in residential spaces.
Buying Guide: Key Considerations for 3 Inch Black PVC/ABS Fittings
- Material compatibility: ABS is common for drains and DWV, while PVC offers strong corrosion resistance and versatility for non-pressurized systems. Confirm your project’s pressure and temperature requirements before choosing a fitting.
- Connection type: Hub connections (slip-fit) are quick and user-friendly; threaded nipples and couplings provide robust, permanent joints but require compatible threading and sealants or tapes.
- Temperature and chemical exposure: For spaces with potential chemical contact or higher temperatures, ABS components often perform well, while PVC may excel in standard indoor DWV applications.
- Size and alignment: Ensure exact 3″ nominal size and check inner/outer diameters for proper slip-fit with your pipe. Flexible couplings can accommodate minor misalignment and reduce joint stress.
- Application scope: Use DWV fittings for sanitary drains and vents; reserve pressure-rated PVC/ABS elbows and couplings for non-pressurized drains where allowed by code.
- Code and compatibility: Local plumbing codes vary; verify approved materials and installation methods for your area, especially for venting and drainage layouts in homes and businesses.
- Durability and maintenance: Look for chemical resistance, UV stability (for outdoor runs), and ease of replacement to minimize long-term maintenance costs.
