I have a refrigerant leak in my high pressure hose - part number BTR4045. Looks like OEM is no longer available and I can't find an aftermarket part either.

My UV flashlight shows it's leaking. You can actually see it bubbling from the fitting.

Can the hard lines be reused and just replace the hose and hose fittings? I googled and only see hydraulic hose repair here in the Denver area.

I'm kind of leery of a used one since it may leak just as bad as the original part.

It’s been a few years ago but I sent mine off to a place that replaced the hose but reused the fittings. They still work perfect.

Im not sure but this may be the place that did it.

Find a shop local that rebuilds AC hoses. I believe they cut out the old sleeve and reuse ac hard line then replace hose and swedge on a new compression sleeve.

Thankfully that is a VERY easy hose to remove and install. I replaced mine back in 2004 when they were still available. The manufacturers stamp says "BURGAFLEX BV" "BTR - 4045X" with goodyear hose. For whatever that is worth, maybe you can contact them still IDK..

But I would remove it from the vehicle and take it to a local but real AC shop, if none are available then I would mail it to one. These places make their $$$ by people wanting cold air ASAP. When you bring them JUST a line into the shop, you're one of the boys and they normally take care of you cheaply.

In a Pinch you can gut the crimp/shield off the outside and replace it with a normal high-pressure hose and hose clamps... BUT that line has a LOT of pressure on it unlike our leaking oil lines, so I would not recommend that at all! BUT you can get some AC HOSE repair kits on amazon/ebay that have better crimps and the right hoses that 'might hold'.

Thanks for the quick replies! I found a local a/c specialty place that can rebuild the hose for $125 + the cost of refrigerant recharge. They're the only local shop I could find that rebuilds hoses in-house and can repair same day.

Online reviews are great, so hopefully it'll be a good experience.

Here in AZ we have AC shops everywhere.

But FYI 125$ sounds fair for the hose.

Could fill yourself with free AutoZone tools and 30$ in Walmart r134. But if they'll do it for a decent price sounds like you got yourself taken care of!
