What Flame King does

Flame King (legal entity YSN Imports, Inc.) is a U.S.-based manufacturer and distributor of propane storage cylinders and related propane-powered equipment, founded in 1998 and headquartered in Pico Rivera, California, with additional operational sites in Commerce (CA), Elkhart (IN), and Riverside (CA). The company designs and produces a comprehensive line of portable propane tanks and cylinders ranging from 0.25 lb to 420 lb in steel and aluminum constructions, certified to DOT, ASME, and Transport Canada specifications in ISO 9002-certified facilities. Its flagship technical differentiator is a patented valve design for 1 lb refillable propane cylinders — the only DOT-certified, legally refillable and transportable 1 lb tank on the market, with a stated 10–12 year service life. The product portfolio has expanded beyond tanks to include OPD valves, gauges, hoses and accessories, forklift and refrigerant cylinders, LP buffer tanks, and downstream propane-consuming appliances (fire pits, heaters, tankless water heaters, pizza ovens, high-BTU burners, grills), plus a Bluetooth-connected Smart Wireless Propane Tank Scale with a companion iOS/Android app.

Flame King sells through a multi-channel distribution model: direct-to-consumer e-commerce via flamekingproducts.com and Amazon, retail distribution through Ace Hardware, Home Depot, Kamps, Propane Depot, and U-Haul, OEM sales to manufacturers (historically including Coleman, for whom the company originally supplied valves before expanding into full cylinder manufacturing in 2000), and B2B sales to propane marketers/distributors in support of a 1 lb cylinder refill and exchange program. The customer base spans residential consumers (BBQ, camping, patio heating), commercial and industrial users (forklifts, warehouse heating, manufacturing), RV and marine users, trade professionals (plumbing, HVAC, welding), and propane marketers/distributors across North America. The company's go-to-market is sales-led, combining retail shelf presence, marketplace listings, and direct B2B engagement.

The company is privately held and led by co-founder and CEO Sam Newman (with co-founder Israel Schochet). It has raised disclosed institutional capital from Main Street Capital Corporation — a $31.6 million debt-plus-equity round in November 2021 and a $66 million round in July 2025 — to support growth across recreational, commercial, industrial, and home propane markets. A 2024–2025 recall of approximately 26,000 refillable 1 lb cylinders due to fire and explosion hazards from leaking valves is a notable safety event affecting the company's flagship innovation line.
