I've wasted a lot of screen time on a similar search in the past week.

The Home Depot and Amazon stuff is crap.

I want unslit (I'm assembling my own cables), and the only decent unslit I thought I could find was via Hilltop in the UK, but while their top bar says they ship worldwide, even after creating an account it refuses to ship to my US address. On top of that, their online chat doesn't work, and emails to them bounce (my ISP is blocked by their spam catcher). I gave up on them two days ago.

For slit:
Fellten stuff seem like they would be high enough quality.

EV West doesn't seem to list any conduit/loom at all, surprisingly, but because I tried to check out a cart order for a week, with their server timing out every try, I gave up online ordering with them at all and bought some kit via Mouser instead (EV West's loss).

EVTV ? I hesitate to list them, but they're in the US:

I still haven't found what I'm looking for: unslit conduit in ~20mm/17mm -- suitable for 16.8mm OD 50mm² shielded cable; I've got 8m/USD$313 of that, and it only took seven days to arrive after ordering from EV Europe.

If you don't need slitted (ie can install before crimping connectors), EV Europe has some lovely stuff.

Unfortunately, they're out of stock on the 20mm size that I need

I had the same problem. Eventually decided on a mesh loom instead of corrugated tube. It's.. an option, at least. I've not run it through the car yet, but it fits over my welding wire well enough and makes it look sufficiently orange.

I bought some split-mesh braid last week, received it a couple of days agao, and it looks good and is a lot more flexible than I'd feared, but I haven't tried to install it yet. I'm considering using it in conjunction with some orange plastic zip ties at the sharper bends -- not that 16.8mm OD cable is going to have sharp bends.

[later: orange zip ties apparently aren't available with UV-resistance, so I'm back to black zip ties for this.]
