Hep2o pushfit grey, Grab Ring Failure ?

[Sharp Point]

complete recipe for disaster if so...

So long as you use the correct pipe insert (so it maintains an appropriate external dia of 15mm) that should not matter to be fair.

Yep, you da man John. I never picked up on it.. embarrassingly!

I don’t use hep to be fair

That made me stop and think and I haven't got one to check Jon. However, our very own 'old bugger' looks to be 100% correct.

His back's beggered, but his brain still works - bless him

How about this fitting it has the metal grab ring first ?

 

[Aire]

Its wrong , the seal goes into the fitting first not the grab ring

Not with the metal grab ring it doesn't, how it is in the photo is correct

 

[Harvest Fields]

How about this fitting ?

That is push fit the other is compression. Different beast altogether.

 

[townfanjon]

Different version but this is correct

 

[townfanjon]

Jon , your fitting is a polypipe with what looks like a speedfit as the actual pipe .

Just had a thought, maybe someone has swapped the rings round on purpose, those score marks look like what could be made if the grab ring was removed physically..... just saying like

Where’s the whistling emoji, when you need one?

The old Hepworth grey fittings with metal grab ring had the O ring on the water side in the demountable Hep fittings and the opposite on the slimmer non demountable fittings.
Even I know that and I don’t use plastic rubbish

I had a leak coming out from this reducing tee just after a month after installation.

You'll be wanting to replace/rework every joint made as part of that installation then. If one is like this, it's a sure thing that there will be others

I must say I've taken apart fittings that old (under a caravan that was going to be scrapped and needed zero-budget work done), bent the metal grab rings to about the right shap, and reassembled using modern Hep pipe and it held (at around 5 bar) until the caravan was scrapped a year later. (No, this wasn't a paid job, in case you're wondering.)
