3 inch Cast Iron Soil 1/4 Bend No Hub x No Hub

3" Cast Iron Soil 1/4 Bend No Hub – For DWV Systems in Commercial and Residential Construction

The 3" no-hub cast iron soil bend is a 90-degree (1/4 bend) elbow designed for use in drain, waste, and vent (DWV) piping systems. Manufactured in accordance with ASTM A888 and CISPI 301 standards, this fitting allows for a smooth directional change in horizontal or vertical piping runs without sacrificing flow performance. It features a no-hub connection suitable for use with shielded or unshielded couplings approved for cast iron piping systems.

• Material: Cast iron, ASTM A888-compliant
• Connection Type: No-hub (hubless), compatible with ASTM C1277 couplings
• Certification: Conforms to CISPI 301 and listed by IAPMO/UPC
• Applications: Non-pressurized DWV systems only
• Temperature Rating: Continuous operation up to 212°F

Installation Guidelines

This fitting is designed for use with stainless steel banded couplings per ASTM C1277 or CISPI 310. Secure using torque-limiting tools to manufacturer-recommended settings (typically 60 in-lbs per clamp band). Ensure alignment and proper support per the International Plumbing Code or local code requirements. Not intended for pressurized systems or potable water conveyance.

Typical Applications

Used in:

• Horizontal-to-vertical transitions in sanitary drainage systems
• Compact installations in multi-story residential and commercial buildings
• Retrofitting and repair work in existing cast iron DWV stacks

Material Consideration

Cast iron offers high strength, rigidity, and acoustic dampening, making it suitable for installations requiring minimal noise transmission. It is naturally fire-resistant and exhibits superior performance in applications where longevity and system integrity are critical.
