Lost or cracked vent cap? The Camco 40034 lets you replace just the cap -- not the entire vent assembly. It snaps onto pipes up to 2 inches in diameter using a spring tension attachment, seating firmly without adhesive or tools. UV inhibitors protect the polar white finish from sun degradation, so it holds up through multiple seasons on the roof.
RV plumbing vent caps sit exposed on the roof year-round. They crack from UV exposure, go brittle in cold weather, or simply blow off on the highway. Replacing the entire vent stack is a much bigger job than it needs to be. The Camco 40034 is a direct cap replacement that snaps onto the existing base using spring tension -- no screws, no adhesive, no plumber required.
This cap is designed for standard RV plumbing vent pipes up to 2 inches in outer diameter, covering the sewer and drain vent stacks found on the vast majority of travel trailers, fifth wheels, and motorhomes. The polar white color blends with most RV rooflines and is formulated with UV inhibitors to resist yellowing and cracking over time.
No tools, no adhesive. The cap compresses and locks onto the pipe with internal spring tension, holding securely even at highway speeds.
Compatible with standard RV plumbing vent pipes up to 2 inches in outer diameter -- the most common size in travel trailers, fifth wheels, and Class A/C motorhomes.
UV stabilizers are mixed into the plastic, not just a surface coating. The cap resists sun-related yellowing, brittleness, and cracking through seasons of rooftop exposure.
Replaces a lost or damaged cap without disturbing the base or re-sealing the roof penetration. One cap included; base is not included and must be present on the pipe.
Plumbing vent caps take a beating. Constant UV exposure breaks down standard plastics within a few seasons. Thermal cycling -- hot summer roofs and freezing winter nights -- causes cracking. And at freeway speeds, an already-compromised cap can simply blow off, leaving the vent pipe open to rain, debris, and insects entering the drain system.
The spring tension design means the Camco 40034 does not rely on friction alone or a snap that can fatigue over time. The internal spring maintains constant inward pressure against the pipe wall, keeping the cap in place even if the pipe has minor wear or slight diameter variation within the 2-inch maximum.
Because this replacement attaches to the existing base, there is no need to cut away old sealant, re-flash the roof penetration, or re-seal around a new pipe fitting. If the base is intact, the swap takes under a minute.
Polar white is the standard color used on most RV roof fittings, vents, and accessories. On white TPO, EPDM, or fiberglass roofs, this cap blends cleanly with neighboring vent covers and plumbing fittings.
This product is the cap only. The pipe base must already be installed and in good condition. If the base is cracked, missing, or improperly sealed to the roof, you will need a full vent assembly replacement, not just this cap.
Inspect all roof vent caps at least once per season -- spring before travel season begins and fall before storage. Look for cracks, UV whitening (which indicates brittleness), and any movement when the cap is pushed. A loose cap is better replaced before a highway trip than after.
