Review on 🔧 Convenient Lu-Hawk R134A Self-Sealing Can Taps with Valve Core Removal Tool – Easy and Efficient Refill Solution! by Wanick Palermo

A valve for freon bottles with self-closing taps did not open the tap. The pierced valve actually worked better with a self-sealing jar. None of these will fit Robinair's pressure gauge kit. If you are using it with a gauge kit, make sure the hose threads match those faucets. Otherwise, make sure you have a faucet that clearly shows that it comes with the required adapter.
