Our most commonly used topping up valve is the A8 Valve. However, where the risk of damage to the fabric of the structure due to vibration or impact is high, the A4 Valve can provide the solution. The A4 Valve is also available with a Deflation probe.

The natural rubber version has a temperature range of –40ºC to +65 ºC. The neoprene version has a temperature range of –30ºC to +65 ºC
