IsoFlex IFV30 HD-16S Flexible Coupling Element – Red (Shore 60)

---

Product Description

The IsoFlex IFV30 HD-16S Flexible Coupling Element (Red – Shore 60) is a high-performance elastomer coupling insert designed to provide vibration isolation, shock absorption, and controlled flexibility in marine driveline and mounting systems.

This flexible element is engineered from IsoFlex’s advanced polymer material, offering superior resistance to fuel, oil, water, and harsh marine environments. The Shore 60 (red) durometer provides a balanced combination of flexibility and load capacity, making it ideal for medium-duty marine applications.

IsoFlex coupling elements are designed to act as a sacrificial and protective component, absorbing driveline stress and misalignment while protecting gearboxes, shafts, and mounts from damage.

Durometer Guide (Important)

• Red (Shore 60): Medium flexibility – general marine use
• Softer cores: More vibration isolation, less load capacity
• Harder cores: More load capacity, less vibration absorption

Correct durometer selection is critical for performance

Parts Desk Insight

The color matters here—red (Shore 60) is the most common “balanced” option. Too soft and you get excess movement, too hard and you lose vibration isolation
