I have some used fire hose that I just replaced in my press. Two 5" hoses clamped to gether (side by side) with scrader valves in place. Have used this set up for multiple pressings with no leaks. I made a longer setup and wanted to see if someone might be interested in it.
valves used
clamped (currently clamps are welded together side by side)
What are the fittings you used and where did you get them? I have been looking for some through wall fittings but all are pretty expensive. These look like what I am after!
I got mine from a place that sells truck tires. They use those valves for tractor trailers. I agree they work really great and yeah cheap! I never even used any sealant.
