TonGass RV Rotating Sewer Vent Covers 2-Pack White — 360° Wind-Following, UV-Resistant

If you own an RV, trailer, or camper, keeping the holding-tank vent clear and durable is essential for odor management and roof longevity. These TonGass vent covers combine a streamlined profile with a rotating fin that aligns with the wind, helping to reduce clogging by leaves, insects, and small debris while the UV-stabilized resin construction resists sun damage and corrosion.

How does the rotation help my RV’s sewer vent?

The built-in fin rotates a full 360 degrees to face the wind, using airflow to steer the intake away from falling debris and to discourage insects from entering. It’s a passive, maintenance-free feature that works without batteries or moving parts requiring frequent attention.

• 360° rotating fin aligns with prevailing wind direction.
• Reduces direct debris entry and splashback into the vent opening.
• Passive operation — no power or routine lubrication needed.

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

The cover is designed to slip over common 1.5-inch PVC vent pipes used on most RVs; adapters can extend compatibility to other sizes. Installation is tool-light: the intake sleeve slides into the existing pipe and secures with the included faceplate and three corrosion-resistant screws, eliminating the need to drill into the roof surface.

• Fits standard 1.5-inch PVC sewer vent pipes; adapters available for other sizes.
• Includes faceplate and three rust-resistant screws for quick mounting.
• No rooftop drilling required — reduces risk to roof seals and liners.

How durable is the TonGass vent cover in sun and weather?

The housing is molded from UV-stabilized resin that resists fading, brittleness, and breakdown from prolonged sun exposure. Corrosion-proof materials and stainless hardware help the unit withstand wet climates and the typical stresses of road travel, keeping the vent functioning season after season.

• UV-resistant resin to prevent sun-related degradation and discoloration.
• Corrosion-proof construction and rust-resistant screws for longevity.
• Low-profile shape minimizes wind drag and reduces stress on mounts.

What comes in the 2-pack and are there maintenance needs?

Each two-pack contains two rotating vent covers, installation manuals, faceplates, and three corrosion-resistant screws per unit. After installation, the covers are essentially maintenance-free — occasional rinsing to remove built-up grime is usually all that’s needed.

• Two TonGass rotating RV sewer vent covers per pack.
• Installation manual, faceplate, and three corrosion-resistant screws included for each unit.
• Minimal upkeep: periodic rinse or quick debris check recommended.

Who is this for: The TonGass 2-Pack Rotating Sewer Vent Covers are ideal for RV owners, camper renovators, and fleet managers who want a simple, durable way to protect holding-tank vents without altering roof structures. If you prefer low-maintenance upgrades that improve vent protection and resist sun and weather damage, this product offers a practical, easy-to-install solution.
