Description

The IsoFlex Flexible Coupling IFC640095 is a high-performance marine driveline component designed to connect the gearbox output flange to the propeller shaft while absorbing vibration and reducing shock loads. This flexible coupling improves drivetrain smoothness, protects critical components, and enhances overall system longevity.

Constructed from high-strength composite material, the IsoFlex coupling allows slight flex under load to compensate for minor misalignment between engine and shaft. This reduces wear on bearings, seals, and transmission components while maintaining efficient power transfer.

The IFC640095 is commonly used in inboard marine propulsion systems, particularly in applications requiring vibration damping and driveline protection.

Parts Desk Insight

Flexible couplings like this are cheap insurance—if you’re seeing vibration or doing a shaft alignment, it’s often worth replacing the coupling at the same time
