You guys are funny no push in type fitting then you think the Shark Bite fitting are the best thing in world  lol



good luck

It does seem a bit incongruous, but a water line blowing off is a whole lot different than a brake line blowing off.

I've never liked the shark bite fittings either - seems the only thing the shark bit was my butt . . . .

I think it's interesting that we have this tendency to reject modern technical solutions for things like air lines in favor of old, outmoded ways of doing things.  Modern is almost always cheaper, except sometimes when it's regulatory upgrades in methods and practices, and while cheaper is often better, but we take a long time to trust it.

I don't  know anything about modern air lines but like many here it would be a hard leap of faith for me to put modern "plastic" air lines in place of good old fashioned rubber and braid lines, or steel/copper hard lines, even though logically I know the new ways are indeed better.  When was the last time you saw a copper line with a fatigue crack, or a corroded steel line, vs the same on a plastic line?

When/if we get a modern constructed coach out to 50 years old, it will be interesting to see what systems made it from the start, and which were replaced. Lots of stock copper lines in the 4104 fleet still going strong.

The abuse of time is hard to replicate in the lab.

And increasingly, the heavy vehicle manufacturer is only focused on the first owner being satisfied, and the second owner being able to repair it for awhile. Much the same as our automobiles for some decades now.

I prefer to put connections together by way of threaded means, leaving the seal snug inside to do one job.

No doubt the time will come when those that follow will giggle, but by then, the materials will have advanced again, making the comparisons hardly fair.

March on technology!

And do it your way!

happy coaching!

I ran all my water lines in pex tubing, but I used all brass fittings with crimp rings.  I just felt more confident in them than the shark bite stuff.

A couple of the hard lines I will be replacing have fatigue cracks right close to the fitting.  My choices are to either replace the entire hard line that is broken, requiring me to make appropriate bends and get the length just right.  Or option B which I have chosen is to just use dot plastic in it's place.  Option B seems much easier and needs to be less precise.  If I were working on brake lines, which I'm not, I might reconsider my strategy.
