Copper particles in copper tubing
Just bought 20 foot nominal 1/2 inch type L soft coil at Home Depot and noticed lots of rather large copper particles inside.
This is for a mini-split line set. Is this O.K. to use like that?
Its kind of freaking me out as I never noticed particles in the smaller dimensions, though they are harder to look into. Can't seem to find any info on it anywhere.
Any help is much appreciated.

Re: Copper particles in copper tubing
If there are particles that are or could become loose then I can't see it being much use mate.
All the fridge copper I've seen is squeaky clean inside. Heard about people getting hold of cheap stuff and the inside looks tarnished.
Cheers,

Re: Copper particles in copper tubing
is it where theyve cut the ends with a grinder/chop saw and the swarf is in the 1st 2ft of each end?

Re: Copper particles in copper tubing
Ah. Swarf it appears to be. I only took off 4-6 inches or so before and that wasn't far enough.
You win the correct answer
Thanks much to both of you. The quick replies were awesome too if not more so.

Re: Copper particles in copper tubing
Think type L is for water only. Keep in mind a mini split on R410A could be running at 600psi in heating mode or in fault conditions...
Would think the best place to get pipe would be a hvac wholesalers.Mostly found in Oxfordshire, UK :)

Re: Copper particles in copper tubing
I NEVER buy soft copper for anything important at the Home Despot, they have been known to have deals with companies to use less material than at the wholesalers.
I found this out on faucets where the same parts are brass at the wholesaler and plastic at HD (same part number). We buy fibreglas insulation in "bats" and where there might usually be 20 bats in a bundle, HD was caught selling it with 19 bats so they could advertise a cheaper cost.
Don't know if they still do it but it was done in the past.

Re: Copper particles in copper tubing
This stuff that I started the thread with is now in use and no problems so far.
Had cut off ~3-4feet in total. What was left, was tapped out and vacuumed for safety as well.
They only had type L in the size and length that was required...
I do agree. Best to buy elsewhere and get proper refrigerant grade to do it completely right in the first place - it not only makes for an easier job that also has the best foundation possible.
