Lippert Components 360 Siphon RV Roof Vent Cap — White Universal Fit, Odor-Reducing & Bug-Screened

The Lippert 360 Siphon Roof Vent Cap is a universal, no-moving-parts vent cover that forces an updraft to exhaust holding-tank odors and keeps pests out of your RV.

Whether you park for the weekend or live on the road, persistent sewer smells and stray insects can make RV life unpleasant. The Lippert 360 Siphon is a compact polycarbonate vent cap engineered to create a continuous updraft that directs odors out through the roof vent before they enter your living area. Its patented geometry works without fans or electrical power, and the integrated fine screen prevents bugs while allowing airflow. This white model blends with most RV roofs and installs simply on standard vent openings.

How does the 360 Siphon reduce odors in an RV?

The vent cap’s design induces an upward airflow across the vent opening, channeling sewer and holding-tank gases out of the roof rather than allowing them to seep back into the coach. By promoting ventilation, it helps maintain a fresher interior environment and supports aerobic conditions in the tank to aid natural breakdown.

• Patented siphon geometry creates a continuous updraft without power.
• Directs vent gases away from living areas to reduce detectable smells.
• Compatible with typical RV roof vent openings for broad application.

Will this vent cap fit my RV’s existing roof vent?

The 360 Siphon is designed as a universal fit for most RV roof vent openings, fitting standard vent cap interfaces used across many manufacturers. It mounts easily to typical vent flanges and is offered in neutral colors to match most roof finishes.

• Universal design works with common RV vent sizes and shapes.
• Simple installation—no special tools or electrical connections needed.
• Available in white (and other colors) to suit roof aesthetics.

How durable and maintenance-friendly is this vent cap?

Constructed from impact-resistant polycarbonate, the 360 Siphon resists weathering and daily wear without moving parts that can fail. The built-in bug screen is washable and easy to inspect during routine maintenance, keeping critters out without adding complexity.

• Solid polycarbonate body withstands sun, rain, and road vibration.
• No mechanical components to break or require power.
• Removable or accessible screen for occasional cleaning and inspection.

Does the 360 Siphon block insects while allowing airflow?

Yes. A fine, integrated screen prevents flies and other pests from entering through the vent while preserving the siphon’s airflow performance. That combination helps keep the coach comfortable and reduces the need for additional pest control at the vent location.

• Built-in mesh keeps bugs out without restricting ventilation.
• Screen placement minimizes clogging while maintaining airflow.
• Easy to access for quick cleaning or replacement if needed.

Who is this for: RV owners, full-time travelers, and weekend campers who want an easy, low-maintenance way to reduce holding-tank odors and keep insects out of their vehicle. It’s especially useful for anyone seeking a passive solution—no electricity or moving parts—to improve interior comfort and protect against pests while matching a broad range of RV roof vent configurations.

Key features:

• Exhausts odors through the roof vent before they enter the RV.
• Universal fit for most RV vent caps and openings.
• Durable polycarbonate construction with no moving parts.
• Built-in insect screen for reliable pest prevention.
