2-PCS RV Water Line Blowout Plug – Brass Air Compressor Winterizing Adapter for RV, Camper, Trailer & Boat Plumbing Systems
Trapped Water Today.
Frozen Pipes Tomorrow?
Don't let leftover water put your RV plumbing at risk. Make winter preparation easier with a compact brass blowout plug designed for controlled air purging.

It's Not Just the Cold.
It's the Water Left Behind.
Water expands when it freezes. If it remains trapped in RV plumbing, that expansion can damage pipes, connections and fixtures. Proper winterization helps reduce that risk before freezing weather arrives.


A Small Fitting.
A Smarter Winter Routine.
Connect a compatible regulated air source to help push residual water out of RV fresh-water lines. A simple addition to your seasonal maintenance kit.
Made of Brass.
Made for Real Maintenance.
Precision-machined threading, a compact metal body and a capped air valve make this practical accessory easy to keep with your RV maintenance equipment.

Less Complicated Setup.
More Confidence in Your Prep.
The fitting connects to a compatible garden-hose-style water inlet, while the air valve provides an attachment point for a suitable compressor air chuck.

Connect. Purge.
Prepare for Winter.
Use as part of your RV manufacturer's complete winterization procedure.
Prepare & Connect
Shut off the water supply and drain the system as directed. Attach the plug to the compatible water inlet.
Use Regulated Air
Attach a compatible air chuck. Set the compressor regulator within your RV manufacturer's permitted pressure range.
Purge & Finish
Follow the recommended valve sequence to clear residual water. Complete all remaining winterization steps.
Never use unregulated compressed air. Do not exceed your RV's specified pressure limit. Protect the water heater and follow manufacturer instructions. Air purging alone may not protect every pump, trap, appliance or plumbing low point.

For the RV.
And Beyond the Campsite.
A useful winterization accessory wherever the fitting and system requirements are compatible.

Prepare for the Cold.
Look Forward to Spring.
A little attention to your plumbing before storage can help avoid preventable problems when it's finally time to travel again.
Everything You Need
