Multipurpose Winterization Kit with Shut-off Valve

The winterizing kit with a shut-off valve is designed for versatile use and includes three connections: a 3/4 male and female garden hose connector. This kit is essential for protecting a wide range of outdoor systems and equipment, including RVs, watercraft, sprinkler systems, and travel trailers.

Flexible Design for Accessibility

Our flexible hose allows the adapter to reach tight spaces with ease, minimizing stress on pipes and fittings. Made for extreme weather conditions, this kit is 100% outdoor rated, virtually indestructible, and impervious to water and oil. It’s also compatible with standard garden hose threading and air compressor quick-connect commonly found in North America.

Enhanced Durability

Pre-assembled to 12.8 inches (approximate), our winterization kit offers a longer length than other manufacturers, providing extra strength and durability. This design ensures a thorough and effective blowout, preventing water from remaining in your sprinkler system and RV water line, thus reducing the risk of freeze damage.

Quality Construction

Crafted from the finest components, our winterization tool is made from solid lead-free brass and reinforced synthetic rubber. The hose, with a 3/8" nominal diameter, is water and oil resistant, ensuring reliability and longevity. All parts are assembled with global components and made in the USA.

Environmental and Cost-Effective Protection

Using our winterization kit avoids the need for antifreeze, which can be harmful to the environment and your health. It provides reliable protection against waterline freezing, saving you costly repairs in the spring. This tool proves to be healthier and more environmentally friendly than antifreeze alternatives.

Quick and Easy Winterization

With our easy-to-use design, winterizing your systems and equipment becomes a simple task. The pre-assembled length and robust construction make it straightforward to blow out your lawn sprinklers, faucets, plumbing, and RVs, ensuring they are ready for winter without the risk of damage.
