4” DOT 407 Pressure Relief Vent



        FUNCTION

        Our DOT 407 Vent combines a low profile, light weight
        design with increased flow rates to meet the most
        demanding needs of virtually any DOT 407 tank.
        See table on next page for specific flow rates.
        The stainless steel valve seat seals on a Teflon®
        encapsulated silicone O-Ring. This O-Ring provides
        complete chemical resistance and a bubble-tight seal to
        meet the latest DOT requirements. The unit also meets the
        surge requirements of 178.345-10 (b) (3) (ii) 1 liter.
