Question:

I need to replace the main propane hose on my travel trailer as it was damaged by rodents. The original hose is 1/2 in. ID with 3/8 male NPT fittings on both ends, FT Flex-Tech Industries P/N H72812-72. Can I buy this hose assembly from trailer, either FT brand or another

The JR Products part # 37207-31485 that you referenced is an exact replacement for your Flex Tech H72812-72 so it would work great. It's 72 inches long, 1/2 inch diameter, and has 3/8 inch fittings on both ends.

I need the same hose for the main LP supply for a 2023 Grand Design Momentum 410TH - the one I need to replace is 96" in length.

@Curtis I wish we had something that long but we do not. Longest we have is 6 foot.
