    Default Hose question

    Dumb question...

    2" hose - What size couplings are available on it?

    I do believe that the coupling would be 1 1/2".

    I had to get a price quote for 3" hose and they asked me if I wanted a 3" coupling or 2½" coupling on the hose. So I would say 2" or 1½" coupling is available on 2” hose. DO NOT quote me on that, I'm just guessing: D best bet is to call the manufacturer.

    I've only ever seen 1.5" couplings.

    Most likely someone has a few different size couplings available, but you should stay with what's being used in your area. This may vary from place to place, but I've never seen anything but 1.5 and 2.5 inch couplings being used around my area. So if we went to 2 inch couplings it would really goof up the mutual aid.
    There goes the neighborhood.

    My volly FD has been using 2 inch hose for about a decade now. Most often it comes with 2 inch couplings with 1 1/2 inch adapters held in place with set screws.

    In my opinion it is wise to go with the 1 1/2 inch couplings, whether you can find a manufacturer that will attach them direct or with the adapters. It makes working with your neighbors a seamless operation because of similar couplings.

    You can also get 2" Storz couplings, I have seen this frequently in Vermont.

    YUP!

    South Burlington uses 2" Storz I believe, as well as other mutual aide companies in the area. All of South Burlingtons hose lines are the rubber "whipe it and rack it" type line with Storz fittings. I was told that the 1.75" handlines expand to 2" when charged, and that is why they use 2" couplings on them.

    Real easy to install fittings to go from a 2.5" discharge down to the 2". Keep a couple extra sets of fittings with your trucks to go from 2" storz to 2.5" female, or 2.5" male...and you're set.

    All our 2 inch has 1 1/2 couplings.

    Coupling size in our dept doesn't change until 2 1/2 hose size.

    About one-half of our attack lines are 2" hose with 2" NST couplings and TFT nozzles with 2" NST thread. You just have to special order them.

    Incidentally, most suctions for small portable 1.5" fire pumps have 2" NPSH threads. (National Pipe Straight Hose, as opposed to NPT, National Pipe Tapered) Tapered threads are for putting together with pipe dope but NPSH is for using gaskets with. The threads are finer than NH (NST) threads.

    We also have 1.5" couplings permanently attached to our 2" hose.
