About this item

  • Blowout plug adapter fitting to winterize recreational vehicles (RV), motorhome, boat, watercraft, camper, water line, and travel trailer by blow out method using an air compressor. This is a safer, healthier, and environmentally friendlier winterization tool when compared with those winterizing kits that use antifreeze.
  • Screws into RV's city water inlet or standard garden hose. Quick-connect attaches to air compressor. Compatible with standard garden hose threading and air compressor quick-connect in USA and Canada.
  • Its short and stubby design allows access to tight spaces. Its solid one-piece construction eliminates any potential for leakage. Knurled surface has no sharp corner so it is more comfortable to grip with your fingers.
  • For your health and safety, this brass fitting is made of lead-free brass which contains less than 0.25% lead. Lead-free brass costs about 30% more to manufacture than regular brass. Lead-free brass is also harder, stronger, and more durable than regular leaded brass. Always wear safety goggles when handling or using compressed air.
  • This heavy duty winterization tool is machined from a solid lead-free brass casting. If you are looking for a quality tool that lasts a lifetime, this one is for you! This blow out plug may also be used to winterize sprinkler systems, drip irrigation systems, soaker hoses, faucets, pipes, spigots, sillcocks, water garden hoses, waterlines, and hose bibbs where applicable.

      This blow-out adapter is an absolute lifesaver for winterizing my RV and boat! It’s super easy to use and makes the process quick and efficient. The durable brass construction feels sturdy and reliable, and it connects seamlessly to my air compressor and water lines without any leaks.
