Aluminum RV Sewer Vent Cap for Roof with Screen

WanDwel's aluminum RV sewer vent cap is a durable roof vent replacement that fits 1" to 2-3/8" outer diameter pipes and keeps out insects and debris.

Replace brittle factory plastic vents with a corrosion-resistant metal cap engineered for RVs, travel trailers, motorhomes and campers. This vent cap combines a screened top, a secure snap-on design and included butyl tape so you can restore proper rooftop ventilation and reduce odors without cutting new holes or complex tools. The powder-coated aluminum resists extreme temperatures and UV exposure for season-after-season reliability.

How does this vent cap stop bugs and leaves from entering the vent?

The cap features an integrated mesh screen that physically blocks insects and plant debris while still allowing air to flow. The screen is mounted under the top cover so it stays protected from wind and impacts.

• Fine metal mesh prevents insects and leaf intrusion
• Screen sits beneath the cap for added protection
• Airflow remains unobstructed for proper venting

Will this fit the vent pipe on my RV roof?

Yes — the internal opening measures about 3.8 inches, designed to clamp securely around pipes from 1" up to 2-3/8" outer diameter. The 5.3" wide base covers typical OEM screw marks, so installation usually fits over existing vent openings without cutting or enlarging the hole.

• Inner diameter ~3.8" to accept 1"–2-3/8" OD pipes
• 5.3" base covers OEM mounting blemishes
• 3" overall height matches most RV vent profiles

How long does installation take and what tools are needed?

Installation is designed to be a short DIY task — about ten minutes for most users. The cap arrives pre-assembled with six corrosion-resistant screws and pre-drilled holes that align with standard vent bases; a screwdriver and sealant are all you need to finish the job.

• 6 pre-drilled mounting holes for quick alignment
• Includes stainless screws and butyl tape for sealing
• Recommend silicone caulk around edges for maximum waterproofing

What materials and extras are included to ensure durability?

The cap is made from powder-coated aluminum to resist cracking, warping and UV degradation common to plastic vents. The package contains everything required to replace a worn outlet: stainless fasteners, butyl tape for an airtight seal, and a metal top cover built to withstand varied climates.

• Powder-coated aluminum body for long-term weather resistance
• Stainless steel screws included to resist corrosion
• Butyl sealing tape (0.5" x 15.75") for airtight installation

Who is this for: This vent cap is aimed at RV owners, weekend campers and fleet maintainers who want a robust upgrade from fragile plastic vents. It's especially useful for those replacing cracked OEM vents, prepping rigs for harsh weather or reducing roof maintenance time. If you want a straightforward, long-lasting rooftop vent solution with included hardware and sealing materials, this WanDwel aluminum sewer vent cap is built to fit most common RV pipe sizes and simplify repairs.
