    I re-did one with ward 3/8" pipe fittings.
    No more problems.
    You worked on a hobby grade machine? And publicly admit it?

    I didn't start a new post about it sir....but if the OP won't go to hobby-machinist.com
    and ask there, I might as well help them best I can.

    And I used "Ward" fittings.....

    I picked up some 290 last night and am trying that first. We can close or delete this post anytime. My intent was not to ruffle feathers, which I thought I made clear in my first sentence.

    I don’t think you need to apologize to the self appointed forum police.

    The loctite is a good call as might be taking the manifold off the machine and filling the leaking joint from the inside with epoxy.

    Or use the loctite with some vacuum on the opposite site

    If the nipple is splined something has to keep it in place
    A steel pin in a groove in the nipple is used for that sometimes
    Can you see a steel pin somewhere in the casting near the nipple??? If so knock it out
    And it has a O -ring perhaps

    there has to be some sort of retainer. press fit on splines would just get blown out.
    either a pin and o ring or it is threaded, just has some permanent loc tite to it. heat it up and remove it by threads.

    Prick ?

    I can clearly see it's a homeshop compressor.

    Has the OP answered to what tools they have avail ?
    or are all you just loving the circle jerk your participating in ?

    BTW chemicals like locktite and epoxy don't like heat now doo they ?
    And most of these small compressors, that "manifold" get's pretty hot in operation.

    Stop waffling, show the larger picture, build a new manifold like many have done with simple hardware store pipe fittings, and get on with life.

    And in the meantime we help somebody (or not)

    No retaining pins are visible and according to someone who claims to know these compressors inside & out, no threads on that nipple, either.

    I decided there wasn't enough meat in the manifold to accommodate a 3/8" bushing. That leaves two options: make a manifold or give 290 a shot. I gave 290 a shot. To my surprise it did pass the first leak test. I still don't expect it to last, but at least I haven't made it worse. The unloader tube also had a slow leak and that's replaced and also passed.

    Just wanted to post a conclusion since I hate when people don't do that. Thanks for all the helpful replies.

    Mike
