Are there threads on the 3/8 female end?

I left a comment above to someone else who said that this product was 3/8” male and female ends. It is not. I purchased the product and installed it today. It is 3/8” male NPT on one end, and 1/2” female flared swivel on the other. I installed this to complete my upgrade from a single tank to a dual propane system. The 3/8” male NPT threads into the outlet of the new dual regulator, and the 1/2 female flared swivel finished the connection to the main line going into my 2016 Coachmen trailer. The 4 foot hose was more than enough. I could have gotten by with 40” to 42”. Good product, good price.

This hose fits the regulator but not my rv. It’s too big. Is there an adapter I could use?

Hi, There are several adapters to fit different type of connections. The most common ones are 1/4”, 3/8 and 1/2” NPT and there are a couple of different sizes of regulators. I have no way to see which one you have or need, I’m sure if you google the RV specs. LP connector, etc. You will find the correct fitment or adapter to your needs. I wish I could help you more. Good luck!

Just to clarify fitting sizes could you screw one end into the other end?

NO. Thermo Plastic Hose Assembly including a 3/8" MNPT x 1/2" Female Flare Swivel, two different sizes on the ends.

Will the 1/2” female side fit on 1/2 black pipe

The female side is a flare fitting it won’t fit npt threaded pipe without an adapter from npt to flare
