The AP MER425H18P is an 18-inch high-flow propane pigtail hose designed for RV and recreational vehicle applications. This essential component provides a safe, user-friendly connection from your propane regulator to a standard LP gas cylinder without requiring a wrench.

Key Features:

• Female QCC Type 1 (ACME) connection with easy-to-tighten swivel nut
• 1/4" male inverted flare fitting for regulator connection
• 18-inch flexible hose length for convenient installation
• Built-in thermal protection activates between 240°F and 300°F to shut off gas flow
• Integrated excess flow limiting device for enhanced safety
• High-flow capacity suitable for RV applications up to 400,000 BTU
• Rated for 350 PSIG working pressure with 400 lbs. pull test rating
• UL/CGA approved and meets RVIA requirements

The thermal protection feature uses a heat-sensitive connector fitting that displaces approximately 1/4" when exposed to excessive heat, automatically closing the cylinder valve and stopping gas flow. The excess flow limiter detects abnormal gas flow and restricts flow to a maximum of 10 SCFH for added safety.
