Fernco Standard Coupling - 500-525mm - SC525

A shear coupling, like the SC525, uses a rigid central band to protect pipe joints from shear forces, such as ground settlement or traffic loads, which could otherwise cause the pipes to shift.

No. Using this coupling on pipes smaller than 500mm will prevent a proper seal and may lead to leaks or joint failure.

Yes, using a torque wrench is highly recommended to ensure the bands are tightened evenly and to the exact pressure required for a reliable seal.

They feature a high-grade rubber sleeve for the seal and a corrosion-resistant stainless steel central band for structural shear protection.

Yes, their shear-resistant design makes them ideal for environments subject to heavy traffic loads and vibration.

Typically, cleaning the pipe surface is sufficient. Avoid using petroleum-based lubricants that could degrade the rubber sleeve.

Ensure the pipe ends are properly deburred and check that the outer diameter does not exceed 525mm.

Verify that the coupling is centered correctly and that the torque wrench was set to the required specification.

Re-check the pipe bedding and structural support; the coupling prevents shear but is not a substitute for proper pipe foundation.
