    The thing you trip over when the engine guys get scared...

    By the way, the 1 1/2 inches is the interior diameter of the water way on a 1 1/2 inch coupling. So if you look at our 1 1/4 inch slug tip the walls of the tip are roughly 1/4 inch thick.
    Great, that's what I was hoping- sounds much beefier than I had pictured.

    I should have quoted your post anyway, as yours was the set up I was asking about...

    That one is will be very short... give the facepice to your FD's qualified SCBA repair tech!

    What size threads are on that 1.25" slug tip? are they 1.5" or 2.5"? I could be wrong, but it seems to me that with 1.5" couplings, that tip would be kinda flimsy- with walls of >1/8"... On the other hand, 2.5" would require an adaptor to do a break and extend. I love the idea, it's simple AND versatile- just trying to get my head around the details.

Boost it to 150 psi engine pressure for the standard 75 psi nozzle at 200 gpm, If you need more, remove the tip and use the 1 1/4" slug supplied with a pump pressure of 190 to 200 psi, and deliver the 300 gpm. Even at 300 gpm the reaction force will only be 91 lbs. I like the thought process. NICE!

    My POC FD uses Key Nitrile Rubber 2 inch hose with a 200 gpm at 75 psi combo nozzle with a 1 1/4 inch slug. We underpump initially to 160 gpm at roughly 55 psi, obviously can go to 200 gpm at 75 psi, or go to the slug for 300 at about 42 psi at the tip. We do not have a major problem with kinking. We do train our guys to understand it is everyone's job to clear the kinks, and especially the last guy on the line as he advanced.

    Teaching proper hose movement should ALWAYS involve training to clear the kinks.

    At the Massachusetts Fire Academy... one of the gems that are drilled into the heads of the recruits is the mantra "everyone is responsible for removing kinks in the line".... everyone meaning from the green as snot probie to a grizzled old Chief.

    Fryed's comments on the Conquest hose also validates the same issues we had after using Conquest for many years. We've since changed to Ponn Supreme which is much better but still has that same propensity to kink just behind the nozzle coupling. We're finding that lots of practice and better technique allows us to use the "whipping motion" but clearly going from the relative stiffness of the 100 psi combo nozzles to the SB and Vindicator requires more than just some classroom theory.
