6 inch Cast Iron Soil Service Weight 1/16 Bend Hub x Soil

6" Cast Iron Soil Pipe Service Weight 1/16 Bend Hub – Precision Angled for DWV Systems

The 6" Cast Iron Soil Pipe Service Weight 1/16 Bend is a 22.5-degree elbow designed for use in gravity-flow drain, waste, and vent (DWV) systems. Manufactured in compliance with ASTM A74, this fitting delivers a precise angle change with long-lasting strength, making it a reliable choice for both commercial and residential installations.

Fabricated from durable cast iron, this fitting features a hub x hub connection and is coated with an asphaltic finish to protect against corrosion. Its design supports installation in above- and below-grade piping configurations, where long-term structural integrity is critical.

Key Technical Specifications

• Material: Cast Iron

Installation Guidance

Install using traditional hub-and-spigot methods with oakum and lead or mechanical couplings as approved by the applicable plumbing code. Proper support and alignment are critical to maintaining joint integrity and long-term performance. Always follow manufacturer and code guidelines when integrating into existing systems.

Common Applications

This 6" 1/16 bend is typically used to navigate direction changes in horizontal DWV lines within soil stack systems. It is appropriate for use in underground infrastructure, multi-family residential buildings, healthcare facilities, and commercial structures requiring resilient and noise-sensitive drainage solutions.

Did You Know?

Cast iron DWV systems are preferred in many jurisdictions due to their longevity, structural rigidity, and ability to suppress airborne noise—making them an optimal choice for high-occupancy structures.
