Air Joust Pole Plug is a replacement valve for refilling Air Joust poles. This Halkey Roberts Valve is a compact fill and deflate valve for rafts and other inflatables. The mechanical sealing offers double seal leak protection, keeping air inside where it needs to be. The two-way mechanism prevents air from escaping during inflation, and can also be twisted open to fully release air. The two-piece construction makes for simple maintenance, and also includes a cap to protect the stainless steel inner spring.
