Viper

The Viper is a Pressure Relief Device with a thermally activated trigger that stretches from 4 to 45 feet long.

The Viper PRD is designed for systems that have a working pressure of 5,000psi.  It also has the added benefit of a higher flow rate when venting in the case of a fire.  This allows gas to escape at a faster and more efficient manner, as it is extremely important to get the gas out as quickly as possible avoiding any possibility of a tank rupture. The internal mechanism utilized in this model of PRD is extremely robust, which increases its performance over the toughest of road conditions, this also includes enhanced corrosion protection.
