Camco Mfg 36143 Brass Blow Out Plug Rv Winterization

Product Description

The CAMCO MFG 36143 is a patented brass blow out plug designed to clear water lines in RVs during winterization and de-winterization. The plug threads directly into the RV city water inlet, allowing a standard air pump to pressurize and purge the plumbing system. Built from heavy-duty brass, it provides a durable, corrosion-resistant connection point for compressed air. This fitting is a seasonal essential for RV owners and service technicians who need a reliable, repeatable method for blowing standing water out of supply lines before freezing temperatures arrive.

This blow out plug is used in the winterization and de-winterization of recreational vehicle plumbing systems. It threads into the city water inlet port found on most standard RVs. The typical workflow involves opening all drains and faucets, threading the plug into the inlet, then attaching and activating a compressed air pump until all water lines read clear. It is equally useful in spring de-winterization to purge any residual air or contaminants before reconnecting to a water supply.

Installation Notes

Installation is performed by RV technicians or knowledgeable owners during seasonal plumbing service. Before attaching the plug, open all faucets, drains, and low-point drain valves to allow water and air to escape freely. Thread the plug into the city water inlet by hand, then connect the air pump to the quick-connect fitting. Do not exceed the rated pressure capacity of the RV plumbing system when applying compressed air.
