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.
