Re: Polyethylene Pipes will not seal at fittings

I'm running some of the black polyethylene pipe in the barn. I
installed the barbed fittings and clamped with hose clamps. They
leaked badly. I was told to heat the pipe and double clamp them. I
did this with a heatgun, but they still leaked. I then used a propane
torch and got the pipe very hot. It even oozed thru the homes on the
clamps, and I tightened the clamps until several of them stripped and
had to be replaced. Unfortunately, after all of this, they still
leak. Is there any sort of sealer I can apply to the fittings before
clamping? I asked a local plumber and he said he has never needed
sealer, but said to try silicone. He also told me to look at the pipe
and see if there is a groove in the inside of it. I looked and there
is none. I even replaced some of the plastic fittings with brass
ones. I have probably invested over 20 hours in this 60 foot run of
pipe, with 6 fittings. I'm about ready to rip the whole thing out and
replace it all with steel pipe. Before I do, I thought I'd ask to see
if anyone knows of a sealer.

Thanks

I just use plastic certified thread sealer. Not all thread sealers will
work with plastic, read the package.
