Are these elbows indoor-outdoor or only indoor?

I installed these outdoors as part of the insulation for my air conditioner back in March (about 6 months ago.) I wrapped all of it with Shurtape LS 300 HVAC Line Set Tape. Even though it gets direct sun for a couple of hours in the middle of each day, it all still looks like new. They have not split at the 'elbow seam'.

Can this be used outdoors for air conditioning pipe?

I used them on my air conditioning pipe; they worked well.
