Stop roof leaks and odors at the source. The Camco 40032 plumbing vent cap slips over your existing sewer vent pipe and restores the weather-tight seal that cracked, faded, or missing caps can no longer provide. A simple, affordable fix that every RV owner can install in minutes.
The plumbing vent cap on your RV roof does two important jobs: it keeps rain, debris, and insects out of your vent stack while still allowing sewer gases to escape freely. When the cap cracks, fades, or blows off entirely -- common after seasons of UV exposure and road vibration -- you lose both protections at once.
Camco's 40032 vent cap is designed as a direct-fit replacement for the OEM-style caps found on a wide range of production RVs. The slip-on design accommodates pipe outside diameters from 1 inch up to 2-3/8 inches, covering the most common ABS and PVC vent stack sizes used in RV construction. No special tools required.
Slip-on design fits vent pipes with outside diameters from 1" up to 2-3/8", covering most standard RV ABS and PVC vent stacks.
Domed cap profile sheds rain and blocks windblown debris from entering the vent stack while still allowing gases to vent freely.
No special tools needed. Slide over the existing pipe, secure per your rig's setup, and the job is done -- typically in under 10 minutes.
Molded polar white color blends with white and light-colored RV roofs and resists fading better than field-painted alternatives.
Most factory vent caps are made from ABS plastic that becomes brittle after years of UV exposure. Road vibration, tree branches, and even pressure-washing can snap the cap or crack its base. Once that happens:
Replacing the cap promptly with a proper-fitting unit like the Camco 40032 prevents all of these downstream issues.
Before ordering, measure the outside diameter of your vent pipe where the cap will seat. Most RV vent pipes run 1-1/2" or 2" OD -- both well within this cap's 1" to 2-3/8" range. If your pipe OD falls at the upper end of that range, confirm the seating is snug before finalizing.
