AP MER42624 RV LP Gas Pigtail Hose 24-Inch Type 1 Acme x 1/4" MNPT

The AP Products MER426-24 is a 24-inch RV LP gas pigtail hose designed to connect a standard propane cylinder to an RV propane regulator. Part of the Marshall Excelsior MER426 series, this hose features a Type 1 (QCC1/ACME) nut connector on the tank end and a 1/4-inch male NPT inverted flare fitting on the regulator end, making it a direct-connect solution that requires no wrench for the tank-side connection.

Key Features:

• 24-inch overall hose length for flexible tank-to-regulator routing
• Type 1 ACME (QCC1) swivel nut connector on the cylinder end — no wrench required
• 1/4-inch male NPT inverted flare fitting on the regulator end
• High-pressure thermoplastic hose construction with fully crimped brass ferrules
• Built-in thermal protection: heat-sensitive fitting closes automatically at elevated temperatures to stop gas flow
• Integrated excess flow limiter senses abnormal flow rates and restricts gas delivery
• UL/CGA approved for safety compliance
• Rated for high-pressure propane (LP gas) service

The MER426-24 is a reliable replacement pigtail for RV propane systems, camper trailers, and motorhomes. It is compatible with standard two-stage LP regulators and DOT propane cylinders using a Type 1 valve. Regular inspection and replacement of LP gas pigtail hoses is recommended every 5 years or sooner if cracking, stiffness, or soot buildup is observed.
