Sealing the BIG air bag fittings - Richard - 04-06-2024

Just file this away in case you ever need it. The air bags on the Ridewell suspension coaches are connected using 1 inch diameter hoses and large 37 degree JIC fittings. They can be a problem to seal back up when changing air bags. Which leads to overtightening, which will be a pain if you ever need to remove the fitting again. I have learned this the hard way. 

I bought some of these. https://flaretite.com/collections/37-jic-304-ss-loctite-coated  as some an experiment. I had the opportunity to play with them today, and installed them on the air bag fittings. I intentionally moderately snugged the fitting nut. Bubble tight at 120 psi. 

Just thought I would pass it on. I had no idea these things existed.

Fantastic!

Added to my Newell file. Not seen them for this application, but I did buy some smaller ones for refrigerant lines. I made some copper refrigerant lines for the Wanderlodge and I found some sealing rings kinda like that. These were made out of some sort of metal with a purple coating on them. 

Here is the kit I am talking about:

Great info for the file shopping cart. Thanks for finding and sharing

Some seals that are used in the aircraft industry for the same purpose are known as Voi-Shan seals.  They are actually conical seals.

I ended up using them on a leaky joint that I could not fix by "tightening a little more" on the hydraulic slide.  I believe that the tube flare had some defect.  They come in all sizes for the "jic" 37 degree flare.

Here is a website for those who want to know more.  https://www.electronicfasteners.com/wp-content/uploads/2014/09/linecard_rosan_conicalseals.pdf

This kit is designed for 45 degree flare and is different than 37 degree flares found in the air and hydraulic system normally found on original "Newell" equipment.  Please be aware.... they may work, but it is not as originally designed.

Yes, excellent point. I was just sharing that is the closest thing I have used, but you are correct they are for 45deg flare fittings not for the 37deg JIC connections.
