The Civacon T195SV Vapor Recovery Vents are designed and tested to take the punishment of temperature from -40ºF to 160ºF (-40ºC to 71ºC). A new cap design threads into the top of the vent which allows for a better seal and eliminates the snap ring system.

The vent’s new spanner nut mounting design allows more freedom for mounting the vent, you are no longer restricted to the normal TTMA bolt pattern.

Seals are new and improved to be compatible with Ethanol, Methanol, Diesel, Biodiesel and Gasoline products being hauled in DOT406 tanks today.
