- Brass construction with rubber cap: Made from high-quality brass for beauty, corrosion resistance, and long life. The included rubber cap seals the connector when not in use to keep dirt and dust out. - Quick connection and disconnection: The 3/8" quick connectors let you run two hoses to your RV at the same time, without worrying about air leaks. An internal shutoff valve automatically stops flow when you unplug one side; you can also use only one connector if desired. - 3/8" Y shunt: A low-pressure gas adapter with two 3/8" female connectors and a 3/8" male connector. It splits a single 3/8" gas line into two, so two devices can be powered from one supply. - Compatibility and scope: Designed for propane and natural gas systems with standard 3/8" fittings. Suitable for gas grills, stoves, patio heaters, fireplaces, pizza ovens, motorhomes, generators, and other gas appliances. - Practical use scenarios: - RV cooking setup: feed both the grill and stove from one supply. - Outdoor entertaining: run a grill and a patio heater from a single line. - Mobile or job-site use: power a generator and a grill from one gas source.
