It’s a cylindrical bellows (elastic corrugated tube) inside a woven cover. The cover prevents expansion in diameter but not length. Water pressue causes the inner tube to extend like the bellows in a pressure guage / switch etc.

The tube perishes near the ends – got one awaiting repair for the Men’s Shed. More of a gimmick than an advantage unless you live in a dolls house.

A broken one is worth salvaging.

The rubber hose is very similar to surgical tubing and is very good for awkward-shaped things that you are gluing up, where clamps are difficult to apply.

The sheath is quite tough and can be used to protect extension cables, maybe as a sleeve on a tow rope or on a TIG welding torch.

My wife was using a cheapie version to water an old ladie’sgarden, when it virtually exploded. The rip was quite long, so scrap.

The lady insisted on replacing it by a big brand name one. After a couple of seasons, that now has a pinhole.

We have stuck with our now old, hard to wind u, conventional hose!
