Corrosion caused by minerals in your water. My water eats aluminum pans if they sit submerged too long.

 

Exactly. Same thing happens here too and that's even with us having very soft sweetwater here.

.

 

If you leave aluminum connectors connected long-term, u cannot unscrew them. I cut them off and replace them.

 

I bought some replacement hose ends at Lowes. I selected brass fittings because the threads wear out on plastic ends. But when I got home, opened the package, they were brass plated aluminum.

 

That would make me really mad.

I got some replacement ends on clearance at Meijer some years back. They were really heavy brass.

 

When we built our house almost 20 years ago, we bought a bunch of hoses to water our freshly-seeded new lawn. After 20 years of use, the brass fittings are in great shape. The female brass fitting is hexagon shape, so if desired, it can be tightened with a crescent wrench.

I do not understand why you use a dremel tool to cut your hose. My chief lawn mower operator has sliced hoses when doing this job. I just use a box-cutter to cut the hose pieces square so I can splice in a repair connector.

I have some coming up to 30 years old. Purchased in 1994.

It was screwed into a female thread on a hose end sprayer and it was leaking. It has never been run over or damaged physically.

I cut it off and replaced it. Hose ends used to be brass, but since they went to aluminum for hose ends, they suck.

I've gone to 100% plastic replacement hose fittings because they NEVER corrode and seize to a metal faucet or lawn sprinkler. I've had to cut too many metal ones off with a Dremel tool.

The only fittings I will buy are the black and green Melnor plastic ones. Link I have 10 or 15 on hand so I don't have to search local hardware stores when I need one.

Buying cheap hoses.

 

Nope. I generally only buy the best hoses I can find---Craftsman and Goodyear. But even those now have crappy aluminum ends.

 

I have never seen a hose with an aluminum end. All of mine, even the recently purchased ones have brass ends. Learn something new every day. Next time I'm looking at hoses, I'll have to look.

 

Some of the aluminum ends are plated or painted to look like brass I hear.

 

I use Teflon tape or antiseize on my ends. Too many corroded fittings, like a few have mentioned. The wife and I are always in antique stores and garage sales. When I see an old, heavy, simple, well made spray nozzle, I buy it. Way better than any junk made these days, and you see them for a few bucks each.

 

What causes a hose end to do this?
Evil spirits.

 

Yeah. The hose Gods hate me. I had one start leaking recently in the middle of the hose.

It was one of those heavy duty nylon reinforced hoses.

Turned out that a mole or vole or rat or something had chewed a tiny hole in it.

 

I have one to patch also , tree limb dropped on it make a little pin hole you notice when you walk past and get a mist

 

It is the norm anymore as hoses are made too cheap and the ends imported and made from unknown materials. Just wait till some idiot figures out a way to make them out of soy plastic. They will get eaten by mice as car wiring is lunch for hungry mice.
