4 inch Cast Iron Soil No Hub Sanitary Tee No Hub x No Hub x No Hub

4 inch Cast Iron No-Hub Sanitary Tee – For High-Performance Drainage Installations

The 4 inch cast iron no-hub sanitary tee is engineered for heavy-duty drainage applications in both residential and commercial plumbing systems. Designed for use in non-pressurized sanitary waste and vent piping, it provides a reliable junction for horizontal branch lines connecting to a vertical stack.

Manufactured to meet or exceed ASTM A888 and CISPI 301 standards, this tee offers dependable structural integrity and long service life under demanding conditions. The no-hub configuration enables fast, secure connections using stainless steel couplings and torque-controlled installation methods.

Product Advantages

• ✅ Robust Material Made from cast iron for high load-bearing capacity and resistance to thermal expansion, fire, and impact.
• ✅ Precision-Cast Dimensions ensure proper alignment with other no-hub system components, minimizing installation errors.
• ✅ No-Hub Profile Compatible with standard no-hub couplings for streamlined joining to other DWV lines.
• ✅ Low Noise Transmission Excellent sound-dampening properties make it ideal for multi-story and commercial buildings.
• ✅ Long-Term Corrosion Resistance Factory-applied asphaltic coating enhances durability in harsh wastewater environments.

Technical Specifications

• Size: 4 inch
• Connection Type: No-Hub x No-Hub x No-Hub
• Standards: ASTM A888, CISPI 301, NSF 372 (lead-free)
• Material: Gray cast iron with interior and exterior bituminous coating

Installation Considerations

This fitting should be installed using torque-limiting wrenches to ensure proper compression of stainless steel shielded couplings. Suitable for underground and above-ground DWV installations in accordance with IPC and UPC codes. Clean pipe ends thoroughly before assembly and verify vertical alignment to maintain flow efficiency.

Common Applications

Widely used in sanitary waste systems, especially at junction points where branch lines intersect vertical stacks. Typical in commercial facilities, apartment buildings, hospitals, and schools where reliability, code compliance, and sound attenuation are essential.

Did You Know?

Cast iron systems are preferred in many commercial builds due to their fire resistance, longevity, and ability to isolate mechanical noise compared to plastic piping alternatives.

For professionals requiring proven performance and code-compliant installation, the 4 inch cast iron no-hub sanitary tee delivers strength, consistency, and long-term reliability on the jobsite.
