RV Winterizing Kit – Brass Blow Out Adapter with Non-Slip Braided Hose, 3/4" GHT & 1/4" Quick Connect for RV, Sprinkler & Boat

• Complete RV Winterizing Kit with Non-Slip Grip
  The 12.8" hose is wrapped in a braided nylon sleeve that stays grippy in wet, cold, or gloved hands—so you can hand-tighten at the city water inlet without fumbling. A must-have in any camper winterizing kit or winterizing camper kit.
• Fits the Gear You Already Own
  Solid brass body with 3/4" male and female garden hose threads, 1/4" industrial quick-connect plug, and a rubber washer for a tight seal.
• Winterize RV with Air Compressor in One Afternoon
  Hook the winterize blowout adapter to your air compressor, thread onto the city water inlet, and push water out of the fresh water lines, faucets, shower, toilet, and low point drains before the freeze.
• One Tool for Sprinklers, Boats & Hoses Too
  The female garden hose end also threads onto sprinkler zones, irrigation lines, garden hoses, outdoor plumbing, boat water systems, and pressure washer pumps. Works as a sprinkler blowout adapter or sprinkler blow out adapter for home systems.
• Built-In Shut-Off Valve
  Start and stop the air at the fitting instead of walking back to the compressor. The sleeved hose shrugs off driveway scrapes, stays flexible in cold weather, and coils without kinking. A reliable piece of your RV winterizing supplies.

Why Choose This RV Winterizing Kit?

Why Winterize with Air Instead of Antifreeze?

An RV antifreeze winterizing kit works, but it leaves residue in your fresh water lines that you have to flush out in spring. Air blowing pushes all the water out without chemicals—no flushing, no aftertaste, no wasted antifreeze. Most RVs can be fully winterized in one afternoon.

How to Use It

Connect the 1/4" quick-connect plug to your air compressor. Thread the 3/4" GHT end onto your RV's city water inlet. Open the built-in shut-off valve and blow air through each line one at a time—faucets, shower, toilet, and low point drains—until only air comes out. Close the valve and move to the next line.

Works Beyond Your RV

The same adapter doubles as a sprinkler blowout connector, sprinkler system blowout adapter, sprinkler winterization kit, or sprinkler system winterization kit—just thread it onto sprinkler zones, irrigation lines, garden hoses, boat water systems, or pressure washer pumps. If it has 3/4" GHT threads, this kit can blow it out. One tool for your entire outdoor water system.

Storage & Maintenance Tips

After winterizing, disconnect the kit and store it in a dry place—the garage or a tool bag works fine. The nylon sleeve protects the hose from scrapes, and the brass body won't rust. Coil the hose loosely to avoid kinks. It's ready to use again next season.

What Makes This Kit Different

Most blow-out adapters are short brass fittings with no hose. This kit adds a 12.8" braided hose with a built-in shut-off valve, so you can control the air at the fitting instead of walking back to the compressor. The nylon sleeve also protects the hose from scrapes and stays grippy in cold weather—making it one of the more complete RV winterizing supplies you can keep on hand.

Specifications

FAQs

Q1: Do I need antifreeze with this kit?
A: No. This kit uses air from your compressor to blow water out of the lines—no antifreeze needed, and nothing to flush out in spring.

Q2: Will this fit my RV?
A: Yes, if your RV has a standard 3/4" GHT city water inlet—the most common size. The 1/4" quick-connect fits most air compressor hoses.

Q3: Is this an RV hot water bypass kit?
A: No. This is a blow-out adapter for winterizing with air. A hot water bypass kit is a separate product used to bypass the water heater when adding antifreeze.

Q4: Can I use it for my sprinkler system?
A: Yes. The 3/4" GHT end threads onto sprinkler zones, irrigation lines, and outdoor faucets. One kit handles both RV and home water systems.

Q5: What if it leaks?
A: Check that the rubber washer is seated properly and the connection is hand-tightened. If defective, contact us for a replacement.
