360 Siphon Plumbing Vent Cap
[S078-310362]

Draws out tank fumes in all wind conditions, while driving OR stationary, with air movement as low as 3 mph! Continual draw of fumes pulls fresh air into the tank, resulting in an increase in aerobic action, significantly increasing the breakdown of solid waste. No moving parts, lower profile (2-1/2") and rugged UV resistant poly-carbonate plastic helps insure long life. Installs just like conventional vents. Includes water sealant collar and built in bug screen.
