    adapter for the 3/8 hose ?

    ok so i bought a3/8 hose to use to pull vacuum with the larger port on vacuum pump but cannot use it with my titan manifold because i need an adapter to be able to attach it to the condenser valve.. any idea on the part name, size, and where to get it?

    well, the standard hose connection on the condensing unit should be 1/4 inch, so you should be able to flare a 1/4 inch piece of copper with a flare nut, braze the 1/4 copper to 3/8 copper, and braze a 3/8 male flare connector to that.

    Or you could just get a flare adapter - 3/8 male by 1/4 female

    just hold your 3/8" hose tight against the 1/4" fitting on the unit and wrap them together with duct tape. Then turn on your vacuum pump, should be good to go. Or just ask someone behind the counter at your parts wharehouse they should be able to help you.

    I bought a set of yellow jacket ball valves and added 3/8 mf x 1/4 ff adaptor to them to be able to connect my 3/8 vacuum hoses to them.. Along with the appion core removal tool it speeds vaccum times up quite a bit.

    That's the same setup I use and it works quite well.

    The more connections and joints you have the more chances for leaks.

    I agree however my set up is routinely pressure tested and evacuation tested to ensure there are no leaks.

    Hey, that's just how I do it. Thought I was the only one.
