Lippert Components 360 Siphon RV Roof Vent Cap - White Polycarbonate, Universal Fit & Bug Screen

The Lippert 360 Siphon RV roof vent cap is a universal, no-moving-parts vent accessory that expels holding-tank odors through an engineered updraft while keeping insects out.

Designed for RV owners who want a cleaner, fresher interior without complicated installation, the Lippert 360 Siphon uses a patented polycarbonate design to produce an upward airflow that vents smells away from living spaces. It installs on standard roof vent openings and works without fans or power, relying instead on its shape to create an updraft. Built-in pest screening and durable materials make it a practical upgrade for long trips, seasonal storage, or everyday camping.

How does the 360 Siphon reduce odors inside my RV?

The 360 Siphon directs air upward from the holding-tank vent, preventing odors from settling back into the RV. Its geometry creates a continuous updraft that carries exhaust away from the roof opening, helping promote better ventilation without electrical components.

• Patented siphon shape generates an updraft to expel air.
• No fans or motors — works passively with wind and pressure differences.
• Fits standard RV vent openings for straightforward replacement.

Will this vent cap fit my RV and how easy is installation?

The 360 Siphon is engineered as a universal-fit vent cap compatible with most RV roof vents, so it can replace or upgrade existing caps with minimal fuss. Installation is typically a simple swap: remove the old cap, position the 360 Siphon, and secure it with the same fasteners or sealant used originally.

• Universal design fits common vent sizes used on RVs.
• Simple, tool-light replacement — no wiring or cutting needed.
• Works as a direct retrofit for many standard vent caps.

What materials and protections does the 360 Siphon offer?

Made from robust polycarbonate, this vent cap resists UV exposure and weathering while maintaining structural integrity. The unit contains no moving parts, which reduces service needs, and includes an integrated bug screen to keep insects and debris out of the vent path.

• Durable polycarbonate construction for long-lasting performance.
• No moving components to wear or fail over time.
• Built-in insect screen prevents pests from entering the vent system.

Can the 360 Siphon be used on boats or other vehicles?

Although primarily marketed for RVs, the universal design makes the 360 Siphon suitable for similar vent openings on boats and other recreational vehicles. Its passive updraft and pest screen functions help maintain better ventilation across a variety of settings.

• Compatible with many marine and RV vent openings.
• Passive operation works without shore power or battery draw.
• Available in white or black to match different exteriors.

Who is this for: The Lippert 360 Siphon is ideal for RV owners, boaters, and anyone with a standard roof vent who wants a low-maintenance way to reduce odor, keep pests out, and improve passive ventilation. It suits DIY installers who prefer a simple retrofit, travelers who need reliable odor control without extra power consumption, and owners replacing worn or discolored vent caps. Whether you camp frequently or store your vehicle seasonally, the 360 Siphon provides a practical, durable upgrade to maintain a fresher interior environment.
