4 inch Cast Iron Soil Service Weight Short Bend Elbow

4" Cast Iron Soil Pipe Service Weight Short Sweep 90° Elbow – Built for Durable, Code-Compliant DWV Transitions

The 4" Cast Iron Service Weight Short Sweep 90° Elbow is engineered for use in gravity-flow drain, waste, and vent (DWV) systems where compact directional changes are required. This fitting delivers high-strength performance and dimensional precision, making it ideal for both commercial and residential plumbing projects.

Manufactured to meet ASTM A74 standards, this elbow features a short radius design that allows tight turns without compromising flow efficiency. The service weight classification ensures it can handle demanding loads and maintain long-term integrity in above- and below-grade installations.

Technical Specifications

• Material: Cast Iron
• Nominal Size: 4 inches
• Angle: 90 degrees (short sweep)
• Connection Type: Hub x Hub
• Standard: ASTM A74 (Service Weight)
• Coating: Asphaltic coating for corrosion resistance

Professional-Grade Benefits

• High Load Capacity: Rated for heavy-duty DWV applications with durable wall thickness and structural integrity.
• Compact Radius: Ideal for confined spaces and close quarters where long-turn fittings won’t fit.
• Acoustic Damping: Naturally reduces water flow noise, making it suitable for multistory residential or commercial use.
• Fire-Resistant: Non-combustible and suitable for fire-rated assemblies per IAPMO guidelines.
• Uniform Sizing: Manufactured to exacting tolerances for compatibility with other cast iron system components.

Installation Notes

Installation should follow standard cast iron practices, including use of oakum and lead or mechanical couplings approved for cast iron soil pipe. Proper joint alignment and support are essential to prevent mechanical stress and ensure long-term sealing. Always reference local plumbing codes for compliance.

Common Applications

This short sweep 90° elbow is typically used to redirect horizontal to vertical soil or waste lines in DWV systems. It is frequently specified in retrofit work, tight mechanical chases, or areas where a compact profile is necessary without compromising on flow performance or durability.

Did You Know?

Short sweep cast iron elbows are distinct from long-turn fittings in that they provide a more compact bend while still maintaining efficient flow characteristics—especially important in tight wall or slab assemblies.

The 4" Cast Iron Soil Pipe Service Weight Short Sweep 90° Elbow delivers the strength, dimensional precision, and longevity required by code and by professionals working on critical drainage systems. Specify with confidence for installations where space is limited and performance is non-negotiable.
