Camco Mfg 40033 Rv Plumbing Vent Kit 1 to 2-3/8 in Od

Product Description

The CAMCO MFG 40033 is a complete RV plumbing vent kit designed to provide a weather-resistant roof penetration for drain-waste-vent (DWV) plumbing in recreational vehicles. The kit fits outside-diameter pipe sizes from 1 inch up to 2-3/8 inches, covering the most common vent stack dimensions found in RV installations. It ships as a three-piece package and includes the vent cap, all required mounting hardware, and putty tape for a watertight seal — no separate trips to the supply house for fasteners or sealant. Plumbers and RV service technicians install this kit when replacing a damaged vent or completing a new DWV rough-in on a coach or trailer.

This vent kit is intended for use on the roofs of recreational vehicles including travel trailers, fifth wheels, and motorhomes where a plumbing vent stack exits through the roof membrane. The included putty tape creates a seal between the vent base and the roof surface, helping prevent water intrusion at the penetration point. Because the kit accommodates pipe OD from 1 inch to 2-3/8 inches, it covers a range of common ABS and PVC vent pipe sizes used in RV DWV systems without requiring an additional reducer or adapter.

Installation Notes

Installation is typically performed by a licensed plumber or qualified RV service technician. Shut off any interior water supply and ensure the vent stack is not under pressure before beginning roof work. Clean the roof surface thoroughly before applying the included putty tape to ensure a proper seal. Follow applicable plumbing codes and RV manufacturer guidelines for vent stack clearances and roof penetration requirements.
