15 inch Stainless Steel Shear Ring

SRC-15 Fernco Stainless Steel Shear Ring – 15" x 2-1/8" x .012 Reinforcement for Flexible Couplings

The SRC-15 Fernco Shear Ring is a stainless steel external reinforcement designed to enhance the structural performance of flexible coupling joints. Engineered to support CPLG 2007969 and similar Fernco-style rubber couplings, this ring limits shear movement and maintains joint alignment under load or ground shifting conditions.

It is commonly specified in underground gravity systems, transition joints between dissimilar pipe materials, and installations requiring code-compliant restraint for couplings subjected to shear forces or external pressures.

Functional Benefits

• ✅ Shear Load Control – Reinforces the coupling to prevent pipe end displacement caused by backfill settlement or pipe misalignment.
• ✅ Material Stability – Constructed from corrosion-resistant stainless steel, suitable for long-term use in below-grade environments.
• ✅ Rigid Support – Adds rigidity around the coupling to support structural integrity in installations without thrust blocks or restraints.
• ✅ Mechanical Compatibility – Designed for use with CPLG 2007969 and other Fernco standard couplings of corresponding diameter.

Technical Specifications

• Model: SRC-15
• Material: Stainless Steel (typically 300-series)
• Dimensions: 15" diameter x 2-1/8" width x .012" thickness
• Application: External shear ring reinforcement for flexible coupling systems
• Standards: Compatible with ASTM C1173 coupling applications and local code requirements for pipe joint restraint

Installation Requirements

Position the shear ring around the flexible coupling prior to or after clamp engagement, depending on configuration. Ensure the ring is centered over the coupling body and secured evenly. Use only with compatible clamp band assemblies as specified by the manufacturer. Installation should conform to project-specific specifications and municipal standards for buried mechanical joints.

Field Applications

Frequently used in sanitary sewer systems, stormwater laterals, and industrial drain line connections where flexible couplings are used across materials such as PVC, clay, ductile iron, or concrete. The SRC-15 provides additional structural support where axial movement or differential settlement is a concern.

Material Consideration

Stainless steel reinforcement rings like the SRC-15 offer enhanced joint stability without introducing galvanic risk. Their non-corrosive properties make them well-suited for soil contact and exposure to wastewater environments.
