The CAMCO MFG 40034 is a white, two-piece RV plumbing vent cap designed to replace a lost or damaged cap without requiring removal of the entire vent pipe assembly. The cap is molded from durable polyethylene and treated with Chimasorb for UV protection, making it suitable for extended outdoor exposure on recreational vehicles. The separate cap design uses a spring-tension attachment combined with a screw-in fastening method, creating a secure fit that resists wind-driven separation. This part is typically installed by RV service technicians or knowledgeable owners performing routine maintenance or storm damage repairs.
The 40034 fits standard RV plumbing vent pipe applications. The two-piece model accommodates 1-1/4 inch and 1-1/2 inch pipes, while the snap-on cap is sized to fit pipes up to 2 inches in diameter. This makes it a versatile replacement across a range of common RV vent pipe sizes found in residential-style plumbing vent terminations on travel trailers, fifth wheels, and motorhomes. It is sold in a package quantity of six units, making it practical for fleet service operations or stocking common repair parts.
Designed as an OEM-style replacement vent cap for RV plumbing vent terminations using 1-1/4 inch, 1-1/2 inch, or up to 2 inch diameter vent pipe.
Installation is performed by RV service technicians or qualified plumbing professionals. Before replacing the vent cap, ensure the work area on the roof is safe to access and that the existing vent pipe is clean and free of debris. The cap snaps and screws into place without requiring adhesives or specialized tools. Follow any applicable RV manufacturer guidelines for vent pipe termination clearances.
