Propane Hose to Connect Between Regulator and Trailer Supply Line

Question:

Upgrading to a two tank system on my travel trailer. The changeover regulator output is 3/8 npt male. Input to travel trailer appears to be 1/4 npt male. I need a hose about 3feet with appropriate connectors

I may be interpreting your specifications inversely - I think you are saying the regulator output is 3/8" male and the input to the trailer is 1/4" male. We don't have a hose that fits to that. However, the output side of most regulators is female NPT and usually 3/8". So you will need a hose that is 3/8" male NPT on the regulator end. The propane service line under the trailer is generally steel/iron and sized larger than 1/4".

If you need a hose to transition from the regulator to the trailer propane pipe, you may want the JR Products # 37207-31485 that is 3/8" male NPT on the regulator end, and 1/2" female SAE swivel on the other end.

Please email me back if I am still not correctly understanding your needs.
