A fellow member's pic post reminded me that I had these. If "Given" the time to build another layout was going to place these at the point of entry. Intended to add a small reservoir of air at low pressure so that breaking the connection would yield a hiss.
These are new manufacture, made where I was the full time Quality Assurance Manager. We produced rubber hoses. Sizes from big enough I could walk through (6-foot plus) to locomotive sanding hoses. Also hose for the Abram M1 tanks and Humves.
Many years ago we made only the brake hoses. Then got into making the whole assembly. Also the same hose was used for railroad track sweepers.
