Specification 1. Nitrogen Purge Tool is designed to regulate proper nitrogen flow with a 50 psi inlet pressure.Maximum pressure of 200psi. 2. Purge Setting = 25-35 scfh@ 50psi Braze setting = 3-6 scfh@ 50psi. Package included 1*Nitrogen Purge Tool Feature 1. Easy to use: Just connect a standard 1/4' refrigerant hose and a standard nitrogen pressure regulator to quickly switch between the three modes of "purge braze close" unlike nitrogen purge tools with dials so troublesome.No fumbling with a flow indicator valve. 2. Extend the service life of HVAC equipment: Help nitrogen flow smoothly into pipe fittings during purging and brazing remove refrigerant moisture and debris prevent oxidation and equipment failure keep pipes clean extend the service life of metal pipes and help you save a fortune on estimated repair costs. 3. Precise and affordable: The air inlet pressure is 50psi the maximum air inlet pressure is 200psi and the nitrogen flow is precisely controlled to achieve more stable and precise purging and welding effects avoiding unnecessary gas waste. 4. Sturdy and durable: All-metal structure durable and wear-resistant compact and lightweight can be placed in tool bags tool boxes pockets and other places you find convenient without worrying about any wear or breakage.
