Question:

Hello, I need to replace the main propane supply hose on my camper. Please note that this is the hose that goes from the regulator outlet definitely 3/8inch Male NPT into the main distribution line for the camper unknown femal connection. Picture attached. The female connection for my old hose is approximately 11/16inch Inner Dimension and 15/16inch Outer Dimension. Could you confirm if this would be a Female 1/2inch Flare connection as noted in this product description? Any help would be appreciated. Thanks!

The MB Sturgis Propane Adapter Hose - 3/8" Male NPT x 1/2" Female Flare Swivel uses a 3/8" fitting on the regulator side and 1/2" fitting on the manifold side. These are nominal fitting sizes so they don't actually measure 3/8" and 1/2", they are actually larger at .675" and .840" respectively.
