Groco HVL-2000 Bronze Vented Loop for 2" Hose

The Groco HVL-2000 is a premium bronze vented loop designed for 2" hose applications in marine sanitation and engine exhaust systems. This essential anti-siphon device prevents backflow while maintaining a one-way venting system that allows air to enter and break siphon action without permitting air and odors to escape into the cabin.

Key Features:

• Heavy-duty bronze construction for superior corrosion resistance in marine environments
• One-way vent valve allows air in to break siphon but prevents air and odors from escaping
• Oversized vent valve removes easily without tools for quick inspection and cleaning
• Threaded 1/2" NPT cap accepts optional barb fitting for overboard venting when required
• Fits 2" hose connections for high-capacity applications
• Includes all necessary mounting hardware for installation

Important Installation Note: Overboard venting is required when the HVL series vented loop is installed in an exhaust system. The versatile design ensures clog-free anti-siphon protection for years of reliable service in demanding marine applications.
