🚐 Brass RV Blow Out Plug – Make Water Line Winterizing Easier
A small connection for your winterizing routine.
After draining your RV water system, residual water may still remain in the lines. This compact brass plug connects a compatible air source to help move that water through open fixtures as part of your vehicle's winterizing procedure.

Give remaining water a way out.
Gravity draining may leave water in parts of an RV's plumbing. Used with a compatible air source and the procedure in your vehicle manual, the plug helps direct regulated air through the system while fixtures are opened.

Fit matters at both ends.
The threaded end must match your RV's designated water inlet, while the valve end needs a suitable air chuck. Check both connections against your own setup before ordering.
A universal fit or specific thread size is not verified on the product listing.

Prepare. Connect. Follow your RV's procedure.
Follow the vehicle manual
Disconnect the water supply and complete the required draining, appliance and bypass steps.
Fit the compatible adapter
Attach it to the designated inlet, then connect a suitable air chuck.
Use regulated air
Use clean air at the pressure specified by your RV manufacturer, opening fixtures as directed.

Made to live in the maintenance kit.
The brass body has hex-shaped sides for handling at the connection. A cap covers the valve between uses; inspect the threads and valve, then store the fitting clean and dry.

Small enough to keep with your RV essentials.
Put it with your other seasonal maintenance supplies so you can find it when the last trip of the season is over. Choose the 1-piece or 2-piece option at checkout.
Air compressor, air chuck and other tools pictured for context are not included in the listed plug options.

One useful part of a complete winterizing plan.
Use it to connect a suitable air source during air-assisted draining, then finish the rest of your RV manufacturer's winterizing checklist.

A few questions before you connect.
Will this fit every RV?
Compatibility depends on your water inlet threads and air chuck. Check both connections before ordering; the product listing does not verify a universal fit.
Does the plug remove water on its own?
No. It is an adapter for a compatible external air source. The air source and air chuck are separate.
What air pressure should I use?
Use a regulator and follow the pressure and procedure specified by your RV and appliance manufacturers. This plug does not regulate pressure.
Does this complete winterizing?
No. Other parts of the water system may need separate draining, bypass steps or RV antifreeze. Follow your manufacturer's complete checklist.
What comes with the quantity options?
Choose either the 1-piece or 2-piece plug option on the product page. An air compressor and air chuck are not included.
Add the right quantity to your RV kit.
Check connection compatibility, then choose 1 piece or 2 pieces.
