12/13/14mm Hard tube offcuts, anyone?

I've put a Wanted post in the Member's Market, but thought I might have better luck in the W/C section...

I've been given a job lot of watercooling gear, including various sizes of hard tube fittings.
I can easily tell which are the 16mm fittings, but could do with working out the sizes of the remainders...

Without a set of precision calipers, the easiest way (I can think of) to tell the size of each fitting is to insert a piece of 12/13/14mm hard tube and see which fit.

If you've got any small pieces of the above sizes and don't mind posting them to me, I'll happily cover the cost. Or even better, if you're local to Portsmouth I can collect.

Many thanks!

Or just use a ruler? You don't need precision calipers to measure differences in whole millimetres. Hell, you could even just place 2 compression caps end to end and sort by which are the bigger of the two.

I wasn't prepared to risk ordering the wrong tubing if my eyes failed me (and I shake like a sh***ing dog, so accuracy with a ruler isn't my best quality).

£7.99 set of vernier calipers via Prime delivery - I now know I've got 16/12mm Fittings and 13/10mm Fittings - irritating that it seems only Alphacool offer acrylic tubing in the latter size.

If you actually have an inner diameter to measure then they're soft tube fittings, not hard tube. Hard tube fittings don't have a barb in the middle.

I was measuring the PETG tube inserts left in the fittings. I'm familiar with soft tube, but hard tube is new to me, so I didn't realise what the inserts were for, until now

Never used hard tube
But
If you do plumbing with plastic pipe
And quick fit/push fittings
You use inserts
So my guess they're to stop deformation from high temperatures etc

Oh I see...well you don't need them. Avoid that junk PETG and just use acrylic.

Only required for PETG because it's junk. Acrylic doesn't require these inserts because it doesn't suffer the same deformation issues that PETG does.

Never knew there were pipe inserts for PC tubing! :O

Alphacool do some as well.

Absolute scam if you ask me. Watercooling experts who should know better force this substandard PETG junk onto the market, and then when the inevitable issues start cropping up with deforming and blown out pipes, conveniently there's an additional product you can buy to mitigate the issues.
