You might try putting the section of hose you want to slide on into a bucket of very warm water. Then you could wet down the metal surface with much less soapy water; it should slide on a lot easier. That’s recommended for connecting irrigation hose to faucet head assemblies.
I replace mine every 3-5 years. You don't have to buy the whole head. Just buy the elastic pouch part like I did. It also helps to keep the head out of sunlight when not in use.
@@OldSoulMillennial I found that if I fill the inside of the first 5 inches of the tubing on each side and dump it out immediately with very slightly soapy water, I was able to slide the tubing completely on to the head.
