KEHIPI Dual Purpose Winterize Adapter Brass 1/4" Quick Plug 3/4" GHT Ball Valve

Dual-Purpose Winterizing Adapter

The KEHIPI brass adapter lets one person blow out water lines on RVs, campers, boats, travel trailers and garden hoses using a standard air compressor. It connects directly to a city water inlet or a male garden-hose thread, and the included 3/4" female-to-female converter covers female-threaded fittings. Solid brass construction avoids the lightweight alloys and brass-coated fittings that can strip or leak. Builders needing a permanent installed valve or a powered pump system will need different hardware.

1/4" Quick Plug to 3/4" GHT Thread

The decisive specification is the 1/4" male air-compressor quick plug mated to a 3/4" male garden-hose thread (GHT). This exact pairing allows the adapter to screw into the standard city-water inlet found on most recreational vehicles and onto common garden-hose fittings without extra reducers. If your water inlet uses a different thread pitch or your compressor hose lacks a matching female quick coupler, the adapter will not connect.

Adjustable Ball Valve for Sustained Blow-Out

An integrated ball valve lets you modulate air-flow velocity while the compressor runs, so you can maintain steady pressure long enough to clear long plumbing runs without over-pressurising fixtures. The valve stem rotates smoothly for one-hand control, keeping the other hand free to watch faucets or low-point drains. Because the valve is brass-on-brass, it resists seizing after seasonal storage better than plastic-shutoff alternatives.
