Press fitting burrs

[NoGearSomeIdea]

Hey everyone,
 

Doing a diy heating install for radiator pipes which are gonna be dormant for ages so didn’t really want to leave flux in them for months.
 

Bought a manual press tool and it’s leaving big burrs & slight deformations.
 

Is this normal? Don’t want to do the whole lot and cry when it comes to testing.

[TonyT]

Are the press tool and fittings compatible with each other?

For peace of mind, you can pressure test now rather than wait until you commission the lot.

[Conor]

Yeah, stick a compression end cap on and start filling with water in stages.

Or hire one of these for a day?

Have you got the correct fittings and jaw combo? Those connections look terrible, I wouldn't want them anywhere near an installation. Maybe better to hire a press fit kit, or even buy and then sell on? £1500 quid now is cheap compared to potentially fixing failed fittings later on down the road.

It’s apparently for M Press fittings, and came with a calibration cert that could have been made in MS Word..

They feel solid enough, wouldn’t be bothered if the fittings weren’t so pricy.

Yeah I’m gonna do that! guess I was just wary of how much abuse hire tools get and it only takes one that doesn’t completely seal…

That’s normal. All my M jaws press like that in my afp101
