Bronze Vented Loop
- 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.
