A Small Part of a Smarter Winter Routine
Help Clear the Lines. Prepare for Colder Days.
Water left inside plumbing can expand as it freezes. Air blowout helps remove residual water as part of your equipment’s recommended winterization process.
Keep the adapter with your maintenance supplies so it is ready when the camping season winds down.
Inside the Connection
Straightforward Hardware. Each Detail Has a Job.
The brass body, threaded connection and air fitting form a compact link between compatible plumbing and a regulated air supply.
Solid Brass Body
A sturdy, corrosion-resistant construction suited to repeated seasonal maintenance.
Garden Hose Thread End
Connects to matching GHT fittings. Choose the thread orientation that suits the inlet or hose you are working with.
Air Quick-Plug Connection
Attaches to a compatible compressor coupler. Check the plug profile as well as the nominal fitting size.
Rubber Sealing Components
The sealing washer helps form a secure connection when properly seated. Inspect its condition before use.
Connect · Regulate · Clear
Make the Connection. Follow Your System’s Procedure.
Begin with the draining and preparation steps specified for your RV, boat or other water system.
-
Fit the Adapter
Confirm matching threads and seals. With the water supply disconnected and pressure released, attach the correct adapter to the designated connection.
-
Connect Regulated Air
Attach a compatible compressor hose and set the regulator before introducing air. Use clean, dry air suitable for the system.
-
Clear Each Outlet
Work through the outlets in the sequence recommended by the equipment manufacturer. Complete any additional winterization steps, then release pressure before disconnecting.
The supplied product guidance specifies 20–30 PSI, with a maximum of 30 PSI. Follow any lower limit required by your adapter or water-system manufacturer. Air blowout alone does not guarantee complete freeze protection.

No Tools Needed — Took 2 Minutes
'Hand-tightened it, hooked up the air hose, and water was shooting out the faucets in seconds. Couldn't be simpler!'

Worked Great on My Boat Too
'Used it on my boat before winter storage. Same garden hose thread fits the marine system perfectly. Saved me a expensive plumber bill.'
One Useful Addition to the Maintenance Kit
For Compatible Connections. Across Your Seasonal Equipment.
Suitable applications may include RV water inlets, garden hoses and certain boat or outdoor water systems with matching fittings.
Compare the connection type and follow the equipment’s winterization instructions before use. Irrigation systems may require a different air supply and a dedicated procedure.

Before Winter Storage
A Few Practical Answers.
What air pressure should I use?
The supplied guidance specifies 20–30 PSI, with a maximum of 30 PSI. Use a regulator and follow any lower pressure limit required by the adapter or the equipment manufacturer.
Will it fit my garden hose or RV inlet?
It is described with a 3/4-inch garden hose thread connection. Check the thread type and male/female orientation against your actual inlet or hose before choosing.
Will the air plug fit every compressor?
Check the quick-plug profile against your compressor hose coupler. A nominal 1/4-inch size alone does not establish compatibility with every quick-connect system.
Does air blowout replace all antifreeze steps?
Follow your equipment manufacturer’s complete winterization procedure. Some systems still require RV/marine antifreeze in specified components, drains or traps after blowing out the supply lines.
Does blowing out the lines sanitize them?
Air blowout helps remove water. Cleaning and sanitizing are separate maintenance tasks and should follow the water-system manufacturer’s instructions.
Can I use it on a boat or sprinkler system?
Only where the connection matches and the equipment permits this method. Confirm the required airflow, pressure and winterization procedure for that particular system.
