19 inch Stainless Steel Shear Ring

Fernco SRC-19 Shear Ring – Reinforced Stability for Flexible Couplings

The SRC-19 Fernco Shear Ring is engineered to provide structural reinforcement to standard rubber couplings, improving resistance to shear forces in buried and above-ground installations. Constructed from corrosion-resistant stainless steel, this component is a critical support element when joining pipes of differing materials or diameters, particularly in high-load environments.

Product Features

• ✅ Stainless Steel Construction – Fabricated from 300-series stainless steel for excellent corrosion resistance and durability.
• ✅ Mechanical Reinforcement – Distributes shear loads away from the joint to maintain alignment and prevent displacement under stress.
• ✅ Compatible with Fernco Couplings – Designed specifically to pair with Fernco Series 1056 flexible couplings for use in DWV systems.
• ✅ Enhanced Joint Integrity – Ideal for installations subject to settlement, vibration, or differential pipe movement.
• ✅ Code Compliant – Meets ASTM C1173 and other relevant plumbing codes for flexible coupling reinforcement.

Technical Specifications

• Model: SRC-19
• Outer Diameter: 2-1/8 inches
• Material: 300-series stainless steel
• Wall Thickness: 0.12 inches
• Application: Reinforcement for 4-inch couplings in DWV, sewer, and drainage systems

Application Use

This shear ring is utilized primarily in gravity-flow and low-pressure pipe systems where movement or shear stress is expected. Common applications include buried sanitary sewer connections, building drain transitions, and horizontal-to-vertical piping changes. It is particularly effective when joining dissimilar materials such as PVC to cast iron or clay.

Best Practices

Install the shear ring between the coupling and the pipe surface to provide additional rigidity to the joint. Use in conjunction with Fernco couplings that are rated for buried service. Ensure proper tightening torque is applied to stainless steel band clamps as per the manufacturer’s recommendations.

The Fernco SRC-19 Shear Ring is a dependable solution for strengthening flexible joints and preserving system alignment under shifting loads. For applications that demand performance beyond the basic coupling, this ring is the industry-standard reinforcement tool.
