The adjustable rubber valve wrench is designed for safe inflation and deflation of kayaks, rafts, and other inflatable boats. It fits most valve types and protects valve cores. - Wide compatibility: works with standard kayak, raft and fishing boat valves, reducing the need for multiple tools. - Secure grip: 6- or 8-tooth design provides firm engagement for precise control and prevents damage to valve stems. - Lightweight and durable: rubber body is easy to carry and stands up to outdoor use. - Adjustable and comfortable: fits a range of valve sizes and styles, enabling smooth operation on any excursion. - Reliable performance: helps control inflation pressure and deflation, minimizing leaks and over-tightening. Use scenarios - At the dock or roadside, quickly inflate a kayak before launch and deflate for compact packing afterward. - On a multi-boat trip, adapt to different valve styles on a raft or fishing boat without swapping tools. - While camping or traveling, maintain and reseal inflatable gear to keep it ready for the next run.
