"Highly effective in preventing fuel theft and diesel spillages" - Chris Smith, Fleet Engineer, Imperial Tankers
The Impregnable is the only anti-siphon to prevent ANY fuel loss due to its unique floatvalve that allows fuel to flow into the tank, but locks off once filling is stopped, meaning no fuel can be siphoned.
