Each hose measures 12 inches and combines a Type 1 ACME nut for cylinder attachment with a 1\/4\" male NPT threaded end for regulator or tee connections (note: this is not a flare fitting). Engineered for heavy-duty use, the assembly is stainless steel braided with a steel inner core and rated to handle high BTU loads up to 80,000 BTUs per hour and pressures up to 250 PSI. The hoses include built-in thermal protection and excess flow shutoff to reduce risk during abnormal events like overpressure or fire exposure.\u003c\/p\u003e\n\n\u003ch3\u003eHow does this pigtail hose connect to my RV regulator?\u003c\/h3\u003e\n\u003cp\u003eThe hose attaches to standard refillable propane cylinders using the Type 1 ACME nut on one end and screws into regulators or brass tees with the 1\/4\" male NPT on the other. Because the male end is NPT rather than flare, it mates directly to devices specified for NPT threading. Installation requires proper sealing tape or thread compound for gas use and hand-tightening followed by a small wrench turn per manufacturer torque guidance.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eType 1 ACME nut connects to 5–40 lb refillable propane cylinders\u003c\/li\u003e\n  \u003cli\u003e1\/4\" male NPT threads for regulators, 4-port tees, or auxiliary ports\u003c\/li\u003e\n  \u003cli\u003e12-inch length gives compact routing with minimal kinking\u003c\/li\u003e\n  \u003cli\u003eUse approved thread sealant for gas lines on NPT threads\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWill this handle high-demand appliances and pressure?\u003c\/h3\u003e\n\u003cp\u003eYes — the Flame King pigtail is rated to deliver up to 80,000 BTUs per hour and withstand pressures up to 250 PSI, making it suitable for most RV heating, cooking, and hot-water applications that use cylinder-fed propane. The stainless braid adds abrasion resistance while the internal components are sized for consistent flow under high-demand conditions.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003e80,000 BTU\/hr capacity for common RV systems\u003c\/li\u003e\n  \u003cli\u003eMaximum 250 PSI working pressure rating\u003c\/li\u003e\n  \u003cli\u003eStainless steel braid for abrasion and puncture resistance\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat safety features are built into the connector?\u003c\/h3\u003e\n\u003cp\u003eFlame King includes passive safety measures to reduce hazards if a fire or a line rupture occurs. The assembly contains a thermal cut-off that reacts to elevated temperatures and an excess-flow valve that restricts fuel flow if a sudden line break is detected. These features lower the chance of uncontrolled gas release until the cylinder valve is manually shut.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eThermal protection that limits flow under excessive heat\u003c\/li\u003e\n  \u003cli\u003eExcess-flow shutoff to reduce flow during a rupture\u003c\/li\u003e\n  \u003cli\u003eSteel braid and solid fittings to resist damage from road use\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat tanks and setups is this compatible with?\u003c\/h3\u003e\n\u003cp\u003eThis pigtail works with standard refillable propane cylinders commonly used with RVs and trailers — 5, 10, 20, 30, or 40 lb tanks — and connects to regulators or 4-port brass tees for multi-appliance distribution. It is ideal as a primary cylinder-to-regulator link or as an auxiliary feed to an installed tee when you need a compact, reliable extension.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eCompatible with 5–40 lb refillable propane cylinders\u003c\/li\u003e\n  \u003cli\u003eFits regulators and 4-port brass tees using 1\/4\" male NPT\u003c\/li\u003e\n  \u003cli\u003eWorks as main or auxiliary supply hose for RV\/trailer systems\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eWho this is for: RV owners, trailer users, and anyone maintaining portable propane systems who wants a short, rugged connector with recognized safety features.
