    Looking through catalogs and what manuals I can find and haven't found info so here I am
    This part is begging to be removed in a overhaul..
    Dates to '57.
    Assuming this was made to accommodate options.

    We are looking at a "J" valve, right? If so, then there should be: the hex nut (plug), a washer, a 300 psi spring, a washer, and the disc and retainer assembly. My diagram is exactly the same as what regulator bj posted.

    That is the manifold end on the right side tank opposite from the J valve on the left side tank, it is merely a plug with a nylon gasket behind it. It serves no other function, it does not accommodate any options such as an SPG

    Thanks Captain.

    Must be there for mfg purposes. Thought it odd to have that verbage stamped on there.

    I just looked at mine from the 1960s, and it also has that nut. I have never removed it, although someone did years ago from the gouges on the nut. It is meant to be on permanently, and not removed even during overhaul unless leaking. I'll look to see what the U.S. Navy Diving Manual, March 1970 says later.


    PS, I just looked at the U.S. Navy Diving Manual, March 1970 which details the breakdown and maintenance of this manifold. There is no reference to removing the Figure and Index #D-18-16, (Part #0532-07, "Cap, Elbow" or its other part, D-18-17, (Part #8210s11, "Washer, Teflon" in that manual. It is not meant to be removed is my conclusion, and I never have.
