Propane Adapter Fitting - 1/4" NPT

Question:

Trying to identify the type and size of a couple brass fittings i have. Trying to convert to 1/4 NPT but not sure what the original thread/fitting is. The original fittings came off propane regulators. I have some pictures if they can help.

It sounds like you have the Propane Adapter Fitting - 1/4" Female Inverted Flare x 1/4" Male NPT, # 37207-30045. This fitting lets you connect your propane cylinder to your regulator with an inverted flare pigtail. It also has an internal back-check that prevents gas from leaking out of the regulator inlet. The advantage of an inverted flare vs. NPT is that the inverted flare doesn't need tape or any kind of sealant. It's sealed well enough without adding anything. They're commonly used on dual changeover regulators which are used in 2-tank systems.

We have several options available at etrailer.com by searching 1/4" NPT, please feel free to email some images that we can identify what you need for your project to be successful.
