I keep reading reviews that say these are hard to get on, even after soaking in
hot water. Any tips to avoid frustration?
Petroleum Jelly helps!
The best is Hot Water and try some silicone spray or WD-40 make sure ends are covered so it dosent get in the hose.
Soak it in hot water, apply silicone to the end of the hose. It's really not that hard to put on. Also, these are purely cosmetic and unnecessary, especially if you use braided hoses.
I put them in hot water for a few minutues. I put a small amount of silicone grease on the hose fitting and the rest is elbow grease. They have to go on tight or they won't stay where you want them.
The bottom line is they do work. They feel a little bit more like plastic than rubber and I did install them on my regulator at the time. If I were going to make the purchase again. I would spring for the little more expensive/ better kind!
