Dang barbed fitting on a 1" hose

Dave Carpentier

Had to change out a fitting on my well draw line to the pump. Some kind of re enforced 1" hose that I had to push on to a barbed fitting. Tried heating up the hose to make it more pliable , but then the hose would bend and bunch up when I tried pushing it on. Frustration ensued.. many attempts at different temps.
Ended up using a pair of medium sized snap ring pliers with some heat shrink on the ends (to protect the inside of the hose). Warmed the hose up and it stretched out nice with the pliers.. slipped right on to that barbed fitting.

Maybe there's a proper tool for that issue, but I thought I'd throw this idea here in case someone can use it.

For smaller hose a pair of needle nose pliers also work.

I push the closed pliers unto the hose until tight and rotate while pushing.

This usually expands it enough to get the barb started.

I wonder if an Uponor expansion tool might do it 🤔

Are you talking about black polyethylene pipe?

The trick is to just heat it enough to get the fitting on, but no more. I also only heat about 2/3 of the barb length on the hose, so it has less chance of buckling.

No. This is flexible line that can be used on suction. Somewhat translucent with a cross-weave of something in it, plus a fairly thick spiral reinforcement strip on the outside.

Maybe it just has a narrow temp range for workability. I've use black pipe before, it pretty much warms up and slips on without too much cussing.

Oh, suction line. That stuff is very hard to install barbs in. Warm it up till it is somewhat soft, and then pound the fitting in with a hammer and block of wood. Those are a pain for sure.

Is this the pipe? Its called tigerflex

That is vinyl tubing, I think. I also use oetiker clamp, too or a hose clamp. I use this tubing to replace the failed condensate drain line on the Muchkins. Works great and saves a ton of money on the standard replacement.

Dave Carpentier

It looks like that on the outside

The ribs look just like that, but I think it has extra layers in the main wall for pressure or wear ?

Larry Weingarten

Hi, A thought... Can you grind the barbs down on the side of a fine grinding wheel so it will be simpler to fit? A hose clamp or two once the hose is in place would be good too

Warm the tube with a heat gun, use a plastic mallet to drive it in.

Seems like an expensive suction pipe? Black Poly p well tube is adequate, unless you need the flexibility?

Dave Carpentier

Larry - True, on the suction side the barbs are a bit overkill. Filing down even the first barb would have helped get the pipe mounted to the diameter.. didnt think of that.

Hotrod - I tried warming it up in various temps with my heat gun.. there might be a 'window' of temp where it would be flex enough to mount but not too soft and bendy, but if so I didnt find it lol.
I thought of the stretching-it-out-from-the-inside idea after I looked at my wirsbo lines and their expansion rings.
