The hose on our aging Samsung Quiet Jet (used to be a Quiet Storm, but I suspect they lost a trademark fight) vacuum cleaner has been a constant nuisance. Most recently, the end toward the handle began splitting:
The fix consisted of a tight duct tape wrap, which has absolutely nothing to recommend it other than expediency.
When the same thing happened on the other end, I sealed it up and added a length of husky heatshrink tubing.
The flared end isn’t particularly decorative, but it serves to reduce the strain on the hose. Alas, there’s no practical way to do the same thing on the handle end.
The replacement cost for the hose roughly equals a new vacuum, so when we run out of bags, this one gets harvested for the shop’s Parts Heap.
