Who uses inserts

[squirrels tail]

The use of inserts on 10mm rolls of plastic covered copper. Brass inserts are available for this purpose, but does anyone use them. They have an O/D of 7.7mm where as the I/D of all of the coils available to me are 8.6 min.

My oil service engineer carries a few inserts round with him to use when he as to.
On installs always use flare fittings.

Inserts should be used on all compression fittings. Look up Specific Oil Solutions. Stuart does a range of oil filters, valves, fittings etc and he does both loose and snug fit inserts. Again inserts should be always be used and has been a requirement for some time I believe.
The other option is to use flare fittings as mentioned above.

Merchants here don’t have them, despite oil installs still very common here.

Even the brass inserts designed for 10mm copper are too loose inside the pipe. It's not always that easy to get flared fittings apart from the fact they are more expensive. I have actually asked fueldump.co.uk who produce these brass inserts to do a bespoke run of 8.4mm O/D inserts and they have agreed to a 1000 min order.

As I said above check Specific Oil Solutions!!!!

8.4mm inserts avaliable from heating world of spares £23 per hundred.
Don't think I will be changing to compression fittings any time soon.

I'm moving to flared fittings. Sick of losing the inserts.

I've been quoted 95 cent an insert and that was for the 7.7mm O/D. bringing the diameter of your pipe down to 6.4mm. Why do they make them so loose. They distort the pipe and olive. Most of the merchants i know think they're for qual.

The inserts I got from HWOS are certainly not loose. So snug they have to be encouraged to go in.

Seems 8.4mm inserts have always been available. news to me. Comments suggest they are not sold by merchants anywhere in Ireland. I found it difficult to get fuel dump.co.uk to make anything other than 7.7mm a name closely associated to OFTEC.

7.7mm fit snuggly into a cut end that has been formed by a manual pipe-cutter. 8.4mm OD fits nicely into 8.6mm ID pipe that has been saw cut and/or de-burred carefully.

Guess which there is more demand for.

It did occur to me that might be the explanation, and if so they were designed by somebody who didn't know what de-burr means. I doubt the 7.7 insert ever comes into play when used, which means these joints would be considered substandard. It's no wonder merchants here don't stock them as plumbers know they're useless and wouldn't buy them. The body's that oversee standards in oil and gas should be on top of this.
