Propane hose change out

[[email protected]]

I replaced my old worn out rubber with braided steel. When I disconnected old hoses, they had a ball bearing, plastic screen & plastic sleeve [see attachments] in them. Are the old hoses made with some check valve or something? Or did these come from the regulator & just dropped into the hoses when I disconnected them?

Thanks in advance - JD

The ballbearing is the anti-backflow valve and is common on gas/air lines. I don't know what the plastic sleeve and screen are.

Thank you Tulecreeper.
the replacement hose doesn't have a ballbearing. Is this an issue?

The female connector should have some sort of backflow valve. Whether or looks like a ball bearing or not is dependent on the manufacturer. Here is a short guide:

Looking at the photos I can not be sure but it looks like the brass check valve (Backflow preventer) screws into a coupler on the host as well as whatever it screws into.

Thank you all!

I would say the plastic screen and sleeve are to hold the bearing in place.
The hoses I just bought as spares have the check valve built in to the ACME nut.

A little more context would be helpful. Trailer? Motorhome? Where is this hose end connecting to?

Pic of the hookup would be helpful too. Trailer pigtails normally don't have anything like this in the end of the hose. They do have a excess flow fuse built into the connector where the green ACME nut is.

But the ball bearing I've only seen in the female connector and are spring loaded and held in place by the interior flange. His picture with the plastic screen and bushing are on the male side.

He is also showing the older style NPT connector. The newer ones use inverted flare.

the new braided hoses seems to be working fine without the anti-backflow bearing
Charles; I have a 2016 Fuzion 5'er [FZ416] - here is the setup

Do the ends that screw into the regulator require any sealant, like gas-compliant Teflon tape or pipe dope?

You might want to take that regulator and heave it off in a lake, Massive propane regulator recall. (Please read all 23 posts in the thread, its informative)

Even if it was not recalled by the trailer manufacturer, it may very well be defective. Grand Design for example recalled them on the bumper pulls, but ignored the fact that the same defective regulators were on 5th wheels also. Follow the link above for information on it.

The hoses are available either way. I prefer the inverse flare as its easier to swap out a hose, but given how infrequently you do that, it really does not matter.

Yes. You need to either use yellow Teflon tape or some gas rated dope

Charles - your link above takes us to Amazon for a "Camco 39562 Clear 3.5" Sewer Hose Adapter"

Not sure what happened there, fixed above but here it is again............

Massive propane regulator recall

Ok, this works. Sorry about that.

NOT on inverted flare fittings.
