PETOL-TITAN VALVE WHEEL WRENCHES are used to provide leverage on hand operated valve wheels. This series of wrenches permits a smooth snap "hammer-action" to make opening and closing stubborn valves easy. Each wrench will fit a variety of sizes and shapes of valve wheels. The special shaped opening in the wrench reduces the chance of slippage when working in overhead or crowded positions.
