Repair or Replace

The Valve on your RIB / Inflatable can be repaired or replaced using parts and components of the same type, or if preferred a complete replacement with a better more suitable valve could be used.

Here we offer solutions and instruction guides:-

A ‘C7 Valve’ is an ideal replacement for many old of worn-out inflatable dinghy or RIB valves. A good quality ‘Valve Doubler‘ can ensure a successful and robust fit into your dinghy. The Doubler simply reinforces the fabric around the Valve. A ‘professional adhesive’ is essential for both Hypalon or PVC inflatable boat fabrics. Polymarine branded products are specifically designed for such a task.
