Had an idea hit me a few days ago when I found an old fitting in our basement and wondered if any one else has ever tried the same thing. I took an old 1 1/4 pipe thread to 2 1/2 fire hose adapter and reduced the pipe end down to a quick connect for a air hose. I then used it to inflate a 1 3/4 hand line from a compressor for use in training. I haven't used it in house yet but did try it at a neighboring Dept yesterday and it was well received there. When hooked to the compressor it was charged to 165 psi it had about the same stiffness as a charged hose line but it did not have the weight. They seamed to have many of the same problems with hose management as a normal line kinking, corners and such. They did grip that it was light though. I was trying for something different for winter training inside other then dragging a dry hose around the station, I just don't trust anyone with a charged hose line in the station to much chance for water damage.

I just wondered if any one else has ever had a similar idea and tried it at all.

We use air in our hoselines in wintertime as well (Alaska is a tad unfriendly to hoses full of water during training), but we took a hose cap and drilled/welded/fitted it with an adapter to accept air from our compressor. When we fill the line sufficient, we just cap it off. I haven't tried just leaving it connected. Their great for hose mazes and feeding through an entrapment prop.
I used this in a FF1 class I'm teaching and it worked out great. I combined it w/ Search and Rescue of the fire house. Very well rec'd.
We also use this in water rescue. We used a bunch of reducers to fill 2.5 inch lines and they float on water just fine. Just another use other than training props.
do you have any pictures of the fittings that you created. I would like to try this at my department.
I like the innovation. However, I have seen hoses fail and I KNOW I wouldn't want to be anywhere near a hose, air charged to 165. So rather than just shoot down your idea, how about charging the line to a working pressure then closing the valve at the pump, preventing flow. This would give you the weight, bulk and a margin of safety from a line opening inside a building.
I like that idea. Float it down stream to catch maybe? That is a good idea. What pressure do you have to use for that?
