Hellerman tyton flexible conduit

[ians]

I use a lot of this stuff ... just finished a deck ready for concrete ... was battling with the flexible conduit breaking off at the couplings.

So I contacted hellerman directly and chatted to someone about this issue ... it turns out that there are 2 types of flexble conduit:

white - V25HT2605 better than the soft rubbish you can buy at the wholesaler ... but not great quality ... it looks like the QC person needs glasses when checking the product as it exits the machine.

Grey - V25HT3905 a decent quality at a much higher price ... which can be used in concrete slabs.

So what is the difference between the 2 ... if you are going to use the flexible conduit in where you plan to pour concrete ... best you dont install the V25HT2605 it is not collapse resistant and will collapse under pressure ... it will also snap when you atempt to glue it into a coupling ... it becomes soft and shrinks once you apply glue.

I thought Hellerman tyton had just changed the colour ... but it turns out I am just ripped off paying the grey price for the white junk.
