Model 356 dual flowmeter regulator is capable of providing two separate independent flows from one common gas source. It is equipped with two Model 55-2 flowmeters that can be set at different flow rates. It is ideal for back purging, trail purging and/or other dual applications. This model features sensitive needle valves for fingertip control and durable, easy-to-read, flow tubes and covers. It is equipped with a tamper-proof, self-reseating, high pressure relief safety valve. The regulator features a brass body, 2" brass dual scale gauge and one-piece encapsulated steel design with internal filter and PTFE Teflon® seat. It has a 5/8" - 18" (F) outlet connection. This model is UL® listed.
