I've done it when it doesn't matter and it's not critical, ie a leak here on the capillary on some cheap bit of gear they want a cheap repair on, on the spot.
If something decent and had to come back for a second visit and be prepared for and they would be willing to pay for, rather replace the whole capillary.
The cap-tube can be one continuous length or it can be divided into many lengths each joined with crimped 1/4" tube - makes almost no difference. Maybe insulating the colder area's of the cap-tube to reduce increased heat ingress at the larger surface area 1/4" pipe sections but it's neither here nor there really.Quote:

However as with Paul H. It would be more normal to replace the whole capillary.
Why do you ask, Have you something specific in mind?

I have seen it done and done it myself in the past...
This was on an 1980's fosters packaged coldroom freezer unit that should be on R502 but is now on R404A, should be a freezer but is being run as a 8C fridge, and was bought on ebay for £500 as a working coldroom...
I think it has a either a leak on it (which i am unable to find) or the cap tube is restricted or possibly a combination of both.
Its colder in the barn, 3C, than in the coldroom and i think it was only the heat from the fan, drain heater and air vent that was keeping it so.
The joint in the cap tube just looks wrong :p
Oh and the ranco stat is iffy and the thermometer has stopped moving....
Might have to call in NRS for some turd polish on monday :D
Monkey I don`t know how you get all the best jobs:D
I think we will have to call you the undertaker soon MS.
Based on the number of your posts which have you resurrecting kit.
Anyone would think these dairy farmers are tight?;)

Yeah i seem to be a magnet for these sorts of things :o
I don't mind patching stuff up and keeping it running, in some ways it can be more fun than fitting new stuff, but i worry that because it keeps breaking down i, rather than the machines age and condition will get the blame.
A pub owner the other day complained that the cost of keeping their stuff running was over their budget, various ancient coldrooms, bottle coolers and some cheapass polar refrig stuff that spares are unavailable for...
Makes me feel like going there for a meal then going back to complain the next week that the food must be faulty because i'm hungry again :D
Jon
yeah jon
i,ve never had any problems joining capillarys the last one i did was on a close control unit distributer and the previous company quoted around 20 grand for a new unit i jointed it regassed and it worked a treat. only problem the customer wouldn,t split the 19 grand between us LOL
mind you i have had a problem on a units fan speed controller capillary snapped, i did the same and a couple of weeks later it went again, most likely due to the vibration, high pressure and age
liked the comment about the meal lol

It was recommended to me from a bloke who layed cables for the electric board.
Cheers,

Andy, thanks for the link to Dr. Guffs.
I now use it on all my projects and my clients love it. It really makes my welds look good.
