A cracked or missing rooftop plumbing vent cap is an open invitation for rain, insects, and debris to enter your RV's drain system. The Camco 40138 RV Plumbing Vent Kit gives you a complete, ready-to-install replacement in one package -- cap, mounting screws, and putty tape included. UV-stabilized black ABS construction resists fading and brittleness through years of rooftop exposure.
The Camco 40138 is designed as a direct replacement for factory-installed plumbing vent caps on a wide range of RVs, travel trailers, fifth wheels, and motorhomes. The wide pipe fitment range -- 1 inch to 2-3/8 inch outer diameter -- means this single kit covers the most common OEM vent pipe sizes without adapters or modifications.
Everything you need to complete the swap is in the box: a formed vent cap, six self-tapping screws, and putty tape for a weatherproof roof seal. No separate trip to the hardware store required.
Fits 1" to 2-3/8" outer diameter vent pipes -- covers the most common OEM sizes found on production RVs.
UV inhibitors built into the ABS plastic resist sun-induced cracking and color fade common to rooftop components.
Ships with (1) vent cap, (6) mounting screws, and putty tape -- no separate hardware needed for a complete install.
Backed by Camco's limited 90-day manufacturer warranty against defects in materials and workmanship.
RV plumbing systems use a rooftop vent pipe to allow sewer gases to escape and to equalize air pressure in the drain lines. Without a functioning cap, that open pipe lets in rain water, insects, and debris -- and can allow unpleasant odors to draft back into the coach under certain wind conditions.
The cap on the Camco 40138 allows gases to exit freely while deflecting rain and blocking pests. It is not a sealed cap -- airflow is intentional and required for the drain system to work correctly.
Installation is a straightforward rooftop job requiring basic hand tools:
