luxlead RV Plumbing Vent Caps 2-Pack for 1–2 3/8" Pipe — White UV-Resistant, Includes Putty Tape & Screws

These luxlead RV plumbing vent caps are a two-piece replacement kit that snaps onto 1" to 2-3/8" ventilation pipes to stop sewer gas from entering your camper while resisting UV and weathering.

When an old vent cap cracks, leaks, or lets odors into your RV cabin, replacing it with a durable, properly sized cap restores ventilation function and keeps the roof sealed. The luxlead kit supplies two white plastic caps, mounting screws and putty tape sized for most camper, trailer and motorhome plumbing vents. They’re molded for outdoor exposure and made to fit common pipe diameters without expensive roof work.

How do these vent caps prevent odors and pests?

The caps sit over the top of your RV’s plumbing vent pipe and channel air while blocking direct entry of sewer smells, insects and debris. Their design allows airflow out of the vent while creating a physical barrier that reduces odor transmission into the cabin space.

• Snap-on cap covers vent opening while allowing airflow outward
• Raised base keeps water and debris away from the pipe opening
• Solid plastic body prevents insect ingress better than worn or broken vents
• Sealing with supplied putty tape limits odor seepage around the mount

Will these caps fit my RV plumbing pipe?

Each cap is sized to accept pipes from 1" up to 2-3/8" in diameter and has a base diameter designed to overlap typical roof openings. Check the inner diameter of your existing vent pipe and the roof hole to confirm fit before installing.

• Inner diameter: 3.8" (intended for 1"–2-3/8" pipes)
• Base diameter: 5.3" to cover most roof vents cleanly
• Height: approximately 3" for clearance above the roofline
• Sold as a 2-pack for front and rear or spare replacement needs

How do I install the luxlead vent cap on my camper roof?

Installation is straightforward and intended for DIY roof repair. The cap snaps over the pipe, and the base secures to the roof with screws; then use sealant or the supplied putty tape to create a weatherproof junction around the base.

• Center the base over the vent pipe and mark mounting holes
• Apply the supplied putty tape or silicone sealant to the base perimeter
• Screw the base down using six mounting points for a stable fit
• Snap the cap onto the mounted base until it locks in place

What materials and durability can I expect outdoors?

luxlead vent caps are molded from UV-resistant plastic formulated to resist fading and cracking from sun exposure. The compact, one-piece cap plus base construction reduces moving parts and maintenance, making them a cost-effective long-term replacement.

• UV-resistant plastic resists sun damage and becomes a stable outdoor component
• Simple snap-fit cap reduces wear from repeated handling
• White finish reflects sunlight to help limit heat absorption
• Includes screws and putty tape so you can seal and secure right away

Who is this for: RV owners, camper renovators, fleet maintenance teams and DIYers looking for an affordable, straightforward vent-cap replacement. If you need a weather-resistant, correctly sized cover that keeps odors, insects and debris out of your plumbing vent while simplifying installation, the luxlead two-pack offers the hardware and sealant to get your roof vent back to working order without specialty tools or roof replacement.
