2 inch Cast Iron Soil 1/8 Bend No Hub x No Hub

2" Cast Iron No-Hub 1/8 Bend – Engineered for Efficient DWV System Layouts

The 2" Cast Iron No-Hub 1/8 Bend is purpose-built for changing flow direction in drain, waste, and vent (DWV) systems by 45 degrees. Designed to meet the requirements of modern construction, this fitting is widely used in residential and commercial applications for its strength, dimensional accuracy, and long-term performance.

Manufactured in accordance with ASTM A888 and listed under CISPI 301, this fitting is compatible with standard no-hub couplings and provides a uniform, code-compliant solution for cast iron soil pipe systems. It supports compact installation needs while ensuring reliable flow capacity and sound attenuation.

Key Features and Benefits

• Material: Durable cast iron suitable for above- and below-grade installations
• Size: 2 inches nominal diameter
• Bend Angle: 1/8 bend (45 degrees)
• Connection Type: No-Hub x No-Hub – for use with stainless steel shielded couplings
• Standard Compliance: ASTM A888, CISPI 301, NSF certified for DWV use

Professional Advantages

• Compact Radius: Enables directional changes where space is limited without compromising structural integrity or flow efficiency
• Noise Reduction: Cast iron provides excellent sound-dampening properties—ideal for multi-story residential construction
• Fire Resistance: Non-combustible and compliant with fire-rated assembly requirements
• Consistent Fitment: Manufactured to strict dimensional tolerances, ensuring compatibility with industry-standard couplings

Installation Recommendations

This fitting is designed for use with mechanical no-hub couplings, such as stainless steel shielded couplings meeting ASTM C1277 or CISPI 310. Proper alignment and torque on the coupling bands are essential to maintain system integrity and code compliance. For best results, installation should be performed by licensed professionals familiar with cast iron piping systems and local plumbing codes.

Applications

Commonly used in horizontal and vertical DWV layouts, this 1/8 bend is essential for creating smooth transitions while maintaining optimal slope and flow direction. Ideal for both new construction and retrofit scenarios in commercial, institutional, and residential buildings.
