Is the CTIS angle valve serviceable

I had to order o-ring and still waiting on it, but I reassembled and seems to be holding for now. I just don't trust the o-ring.

How did you get the inner portion out? I was able to take the cap off but that's it.

The check valve kinda protruded out as I took the cap off, due to a little air still in tire. I just grabbed with my fingers. Below is a picture of parts after cleanup and putting a small piece of rubber between valve and union.

UPDATE: OOPS ignore rest of post below....... my bad. see you did just that in your first post so suspect you will do it with above post as well.

UPDATE TWO........... ok.. guess your not going to upload them so did it to preserve a good archive for future readers seeking an answer to this issue. See quoted post few pages ahead with pics uploaded.

Do future readers a favor. After posting. Go back and edit your post.... you will see that taptalk actually is hosting your pics and inserted a URL to the image in your post. While editing You can use this url to upload the picture to this site so they get saved on this board. Reason being odds are tapatalk will stop hosting pics. When they do threads like this one which is full of great information will end up useless.

ps... changed IMG to IMx in above URL's so you can see the url's and where the images are actually hosted

The Dana part number for the regular elbow is 673240, a truck part store should be able to order them for you.

Picked up elbow today, looks like the other two on the truck. I didn't install yet because I wanted to see if suspected o-ring was the culprit. So far tire is holding air after O-ring change out. If not, I'll change out elbow, but at least I have one on hand. Thanks to all that participated.

Hopefully the repaired elbow continues to hold air, I gave up on mine and used the new elbows due to continued leaks. I have had good luck buying the CTIS parts new from Dana via the local truck parts store. They also have been helpful with the part numbers.

How tight do you tighten that right angle connector on to the stem? Hand tight, or more? I tightened one a little too much and drove the internal o-ring onto the threads of the stem (where Schroeder valve goes). The o- ring was damaged. It is supposed to seat on the smooth end of the stem, not the threads, right? I think now that hand tight works.

The o ring seals on the smooth part of the stem, hand tight is fine.
