GASPRO 15 Inch RV Propane Hose with 1/4 Male Inverted, Camper Propane Hose Replacement for 2-Stage Auto Changeover Regulator, 2-Pack

QCC1 Acme Nut x 1/4 Male Inverted Flare (Non-NPT): Each hose features a standard QCC-1 / Type 1 fitting on the propane tank end and a 1/4 male inverted flare on the regulator end. This is the correct interface for most RV 2-stage auto changeover regulators, including Flame King ACR-2a, Camco, Fairview, and Marshall Excelsior models. ️ Note: The regulator end is 1/4 inverted flare, NOT NPT thread — please verify your regulator inlet before ordering to ensure compatibility.,WIDE COMPATIBILITY FOR DUAL LP TANK SETUPS: Designed as a direct replacement pigtail hose for RV dual propane tank systems. Works with travel trailers, fifth wheels, pop-up campers, and motorhomes equipped with a 2-stage auto changeover regulator. Also compatible as an auxiliary propane supply line when connected to a 4-port tee fitting. Each pack includes 2 hoses — one for each LP cylinder in your dual-tank configuration.,PREMIUM BRASS & RUBBER CONSTRUCTION — BUILT TO LAST: The hose body is made of flexible, weather-resistant rubber that maintains performance in both hot summers and cold winters. Both end fittings are crafted from solid high-quality brass, providing superior corrosion resistance and a leak-free seal. The 15-inch length is optimized to connect LP tanks to the regulator without excess slack or tension — no kinking, no twisting under the tank cover.,TOOL-FREE INSTALLATION IN MINUTES: The QCC1 acme nut threads on by hand — no wrenches or pipe tape required. Simply hand-tighten the tank end onto your LP cylinder valve, then connect the 1/4 inverted flare end to your regulator inlet. Always perform a soap bubble leak test after installation and each time you swap tanks. Replacement is recommended every 5–10 years or immediately if cracks, stiffness, or odor are detected.,2-PACK VALUE : Get two 15-inch propane pigtail hoses at a price that makes sense — keep one in use and one as a spare.
