  • One main vertical outlet (hub connection)
  • Two opposing 90° inlets for connecting horizontal drain lines
• Material Options:
  • PVC / ABS – Lightweight, corrosion-resistant, ideal for residential and commercial plumbing
  • Cast Iron – Strong and durable, used in heavy-duty drainage systems
  • Copper / Brass – Occasionally used in specialized applications
• Connection Type:
  • Hub (Socket) Ends – Designed for solvent welding or rubber gasket connections
• Applications:
  • Wastewater and venting systems in residential and commercial plumbing
  • Connecting two horizontal branch lines to a vertical drain stack
  • Used in vent systems to maintain proper air circulation

Installation Considerations:

• Must be installed in drainage applications where proper venting is ensured
• In some cases, a wye fitting with 45° elbows is preferred for smoother flow and reduced risk of clogging
• Ensure compliance with local plumbing codes for correct usage
