Persistent Parker Parflex Pinhole Problem

[Mikey P]

A 3 year old, 110' run of Parflex finnaly got a case of the pinhole warning leaks at the machine end.
I had the local Hydraulics shop cut off a foot and re-crimp

3 times now after a day of use the pine holes come back under the solid rubber bend restrictor.


Never ever seen this happen before with well over a decade of Parfex use on three trucks..


Have you?

 

[Bob Savage]

I've had a couple pin leaks and did the same thing that you did.

I nixed the bend restrictors and have not had any problems since.

 

[hogjowl]

The bend restrictors trap heat. That hose depends on the heat being able to radiate away.

 

[Cleanworks]

Use a spring bend restrictor instead of solid ones.

 

[Doug Cox]

When it happens repeatedly after recrimping I usually just toss it. I buy one length a year.

 

[Mikey P]

I hate to toss 100ft

Get Cobbs Thermoplastic hose.

Get Cobbs Thermoplastic hose.

@Matt Wood had problems with it.

I've gone through miles of Parflex without issues.


Our only hose provider doesnt deal with Parker so I may be going back to steel braided..

That's a contradiction.

[Mikey P]

Yeah, but I need a reliable local patcher..

Have you?

Are you running it(parker) right off the tm?


I've had no issues, same parker for over 5 years. Just got some new hose(parker) and it has no memory issues what so ever. It's great. I run 50' of steel braid off the truck then the parker.

I’m surprised there’s not a decent hose crimp shop near you

Larry's blue plastic hose is kick butt also! Super light.

I bought two no problems, What was Matts problem?

I dont think its the crimp its the hose.

 

[BIG WOOD]

I had mine hooked up to the tm. It got too hot. So now I have it hooked up to a 25ft hose that’s connected to the tm

 

[Hack Attack]

Yeah, but I need a reliable local patcher..

Are you dealing with a franchised hydraulic company?
I had problems getting crimps done properly because it wasn't their hose that I was bringing in and they were always blowing. They kept saying we dont have the tech specs on that hose you have to buy ours its better.. one of their techs said on the side take it to someone else your getting the standard bs franchise line

 

[sassyotto]

no problems here but I switch mine out every year or two. I sell the old one on ebay for 50% of new. Theres always a cleaner that wants something cheap, so its like getting new hose for 50% off! Then I never have to worry if its gunna bust on me.

Did it bubble like Ron Werner’s?

 

[roro]

Is the hose being bent too much where it exits machine - manufacturers recommendation is "Minimum Bend Radius (mm) 38"

WE have been using this hose for many years and get a long life out of them. When we do get pin-holes it is usually anywhere along the length and a sign that it's up for replacement - usually the external cover has got manky and split well before any pinholes appear.

[BIG WOOD]

yes

 

[Hack Attack]

yes

did it bubble on/just past the crimp?
Or randomly down the line?

 

[BIG WOOD]

It bubbled right at the machine where it was hooked directly to just past the crimp in one big bubble. So I hope it doesn't happen again, since it's no longer hooked up directly to the tm

 

[Hack Attack]

that seems possibly more like a crimping fault not so much the hose?

Read my post 5 or so above, I had that prob with 1 of Joes hoses till I took it elsewhere.

Not saying his is the "best" but the problems faded when I went elsewhere for crimping
