3 inch x 3 inch x 1-1/2 inch Cast Iron Soil Tapped No-Hub Reducing Tee – Hubless DWV

This 3 inch x 3 inch x 1-1/2 inch cast iron reducing tee is engineered for use in no-hub sanitary DWV (drain, waste, and vent) systems. The fitting includes a tapped 1-1/2 inch branch and provides a reliable means of reducing system size while maintaining structural integrity and consistent flow characteristics. Commonly used in horizontal and vertical stacks in commercial, industrial, and multifamily residential applications.

Performance and Material Standards

• ✅ Construction: Cast from gray iron per ASTM A888 or CISPI 301 for hubless soil pipe and fittings
• ✅ Design: Three-way reducing configuration with two 3 inch in-line ports and a 1-1/2 inch tapped branch
• ✅ Finish: Asphaltic coating for corrosion resistance in soil, concrete, and atmospheric environments
• ✅ Joining Method: Compatible with stainless steel shielded couplings per ASTM C1277 or CISPI 310

Key Advantages for Professional Use

• ✔ Code-Compliant: Meets UPC and IPC requirements for cast iron DWV systems
• ✔ Fire-Resistant: Non-combustible material suitable for fire-rated assemblies
• ✔ Acoustically Superior: Significantly reduces pipe noise transmission compared to plastic systems
• ✔ Mechanical Strength: Maintains shape under load, ideal for use in slab and underground installations

Typical Applications

• • Branch connections in vertical stacks
• • Horizontal drainage line transitions
• • Multi-story waste systems in commercial and residential buildings

Installation Considerations

Use with calibrated torque wrenches and approved no-hub couplings. Adhere to local code-mandated installation techniques and support spacing. Secure placement and alignment are critical for maintaining proper gradient and joint integrity in DWV systems.
