Question:

Hey, I’m changing the propane supply pigtails on my RV. but the new 1/4 fitting doesn’t fit my regulator. It’s too small. What adaptor do I need to make the connection work?

Hello Tim, thanks for reaching out. It sounds like you are needing the Propane Adapter Fitting # 37207-30045. This will attach to the regulator and allow you to use a standard pigtail.

Hey Tim, did the propane adapter fitting make the connection to your regulator work the way you needed? Knowing how it fit could help others updating their RV propane setup.
