[Upgraded Propane Refill Hose] The propane extension filling hose is newly designed with a colorful dial gauge that matches the tank gauge level indicator, allowing you to read and monitor the gas level without removing the tank, and can detect leaks. [How to Use] Connect the QCC1 adapter to your tank first and open the gas for a few seconds; otherwise, it may not work. Then connect the 1lb adapter to your small propane bottle. If you do not want to refill, close the refill valve. This allows you to refill the 1lb propane bottle directly from a 20-50lb propane tank without having to move or carry the tanks, as the 1lb propane bottle is easy to carry. [Product Standards] The length of the upgraded propane refill hose is 3 feet / 36 inches / 91 cm. Rated pressure of the propane extension refill hose: 350 PSI high pressure. [Durable Material] The 36-inch propane refill hose is made of durable quality rubber with weather resistance, anti-corrosion, anti-aging, airtightness, heat resistance, and flexibility features. The QCC1 male connector, propane tank gauge, and 1lb bottle tank adapter with shut-off control valve are made of premium solid brass for secure and long-lasting use. [Wide Application] The 1lb propane filling hose can be used with heaters, portable grills, camp stoves, tabletop grills, and more, ideal for tailgating, camping, heating needs, or outdoor cookouts.
