Brass RV Winterizing Blowout Plug
🚐 Brass RV Winterizing Blowout Plug — Help Clear Residual Water Before Storage
Make water-line blowout part of your RV’s seasonal preparation. This Brass RV Winterizing Blowout Plug connects a compatible water inlet to an external air source, helping move residual water out through the system’s open outlets as directed by your RV manufacturer.

💧 Support Your Seasonal Drain-Down Routine
Draining and preparing your plumbing before cold-weather storage is an important part of RV care. This adapter provides an air connection for the blowout stage of a compatible system’s winterization procedure. It does not clean or sanitize the lines, and it does not replace the remaining steps required for tanks, appliances, or drain traps.

🔗 A Straightforward Connection to Your Air Source
Screw the threaded end into a matching inlet, remove the protective cap, and attach a compatible air chuck to the tire-style valve stem. Use clean, oil-free air with a separate pressure regulator, following your RV’s specified outlet sequence and pressure limit. Confirm the adapter’s pressure rating before use and stay within the lowest limit of all connected components.
The plug is an adapter; it does not generate or regulate air pressure. An air source, hose, air chuck, and regulator are required separately.
⚙️ Brass Body with a Protective Valve Cap
The brass body forms the threaded connection, while the removable cap covers the air valve during storage. Its compact format makes it easy to keep with your RV maintenance supplies, ready when you prepare the water system for storage.

📏 Match the Connections Before You Buy
Check your RV inlet’s thread size and type, the required seal, and your air chuck’s compatibility with the valve stem. Overall dimensions alone do not establish thread compatibility. Confirm the selected package contents; multiple product views and caps in the photos do not establish the quantity supplied.

🚚 Shipping: US$5.99. Free shipping on orders of US$80 or more.
