Vented Loops

Vented Loops

THE CONCEPT

            • Made in the USA 
            • Allows air to enter to break siphon, but does not permit air and odors to escape!
            • Cap is threaded 1/2" NPT to accept a barb fitting if you wish to vent overboard.
            • Overboard venting is required if PVL or HVL series is used in an exhaust system.
            • HVL and PVL series vented loops assure clog-free anti-siphon protection for sanitation or engine exhaust systems.
            • The oversized vent valve can easily be removed for inspection or cleaning without tools.
            • Mount Hardware is included.
