❄️ SMART RV WINTER PREPARATION

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.

Brass RV winterization blowout plug
🔩 Solid Brass Construction
💨 Compressed-Air Purging
❄️ Winterization Essential
THE PROBLEM YOU DON'T WANT TO IGNORE

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.

HOW IT WORKS

Connect. Purge.
Prepare for Winter.

Use as part of your RV manufacturer's complete winterization procedure.

01

Prepare & Connect

Shut off the water supply and drain the system as directed. Attach the plug to the compatible water inlet.

02

Use Regulated Air

Attach a compatible air chuck. Set the compressor regulator within your RV manufacturer's permitted pressure range.

03

Purge & Finish

Follow the recommended valve sequence to clear residual water. Complete all remaining winterization steps.

⚠️ Important Safety Information

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.

QUICK ANSWERS

Good to Know
Before Winter.

What does the blowout plug do?
It connects a suitable regulated air source to a compatible water inlet, helping expel residual water during the winterization process.
What air pressure should I use?
The product page suggests 20–30 PSI, but you must follow the RV or plumbing manufacturer's pressure instructions and use whichever limit is lower.
Does it fit every RV?
No universal fit is guaranteed. The listed water connection uses 3/4-inch garden hose threading. Confirm compatibility with your specific inlet.
Will it connect directly to my compressor?
The pictured version uses a capped air valve that may require a compatible tire-style air chuck. Verify your fitting before use.
Do I still need antifreeze?
Depending on the RV design, antifreeze or additional treatment may still be required for traps, pumps, drains and other areas. Follow your manufacturer's instructions.
Is the package one or two pieces?
The listing offers 1pc and 2pcs variants. Please choose the desired option before checkout.
