Winterize Mfg Heavy-Duty Quick Connect Blow Out Plug for RV, Travel Trailer, Boat and Camper

The original patented (U.S. Patent # D600,323) Blowout Plug design properly clears freshwater lines to winterize your RV, travel trailer, camper, boat, pressure washers, sprinkler systems, or any water line that has a female garden hose connection. The purging of water helps prevent damage/destruction to water lines from freezing temperatures. If used properly the anti-freeze that is usually injected into the drinking water lines may not be needed. The new quick connect design of the Blow Out Plug provides a direct, hands-free, single person connection between the city water port and air compressor. This professional quality fitting is not a clumsy blow out hose made of multiple parts, but is a compact metal tool milled from a solid single piece of aluminum. It is lead-free (unlike some machined brass) and safe for drinking water lines. It combines a quick connect air compressor plug with the standard garden hose thread. Just lock the air compressor in place with your new adaptor and walk away. This provides a cheaper, quicker, easier, safer, and more efficient method of winterizing a RV water system. Our blow out valve is not only for RV winterization, but is also engineered for fresh/saltwater marine use. The quick-connect air compressor fitting on one end of the tool is a standard industrial " quick-connect air compressor plug. This size and shape is the most common style being used and will attach into any " universal quick connect coupling. The middle section of our RV blow out adaptor consists of an over-sized 7/8" hex nut. The other end of the RV blow out tool is a standard " male garden hose thread. This is the same thread found on all garden hoses, RV and boat city water connections. The male garden hose end is bored to create a concave shape. This shape will allow the plug to envelop the small gasketted screen that is typically found on RV city water inlets. The result is a tighter/leak-proof connection.
