Replaced the manual valve with this and it works great. I used propane teflon tape on the connections and have no leaks at all. Well worth the peace of mind when camping in the mountains where it gets chilly at night. No more waking up to a cold camper and having to go outside to switch tanks. ## Features - Allows removal of an empty cylinder for refill without interrupting the propane supply - For RVs with dual propane tanks, it automatically switches from the primary tank to the reserve tank when the primary is empty - UL LISTED: Inlets are 1/4" SAE inverted flare, and the outlet is 3/8" NPT female pipe thread; rated for 345,200 BTU - Double-stage design maintains constant gas pressure under changing demand and conditions; the regulator is factory set at 11" WC (water column); lockout pressure is up to 14.9" WC - Compatible with Flame King's 48-inch Thermo Plastic Hose (Model 100383-48) and 12-18 inch INVERTED FLARE Pigtails (Models E12INPT, E15INPT, or E18INPT) - For your safety and to ensure leak-free performance, these regulators are assembled using high-strength thread-locker (Loctite) on the adapter connections where the pigtails are attached.
