This is a UAC brand A/C discharge hose assembly – basically one of the main hoses that carries refrigerant through your car's air conditioning system.

Part number HA 11151C.

It's a brand new, aftermarket part made to replace the original one.
UAC says they engineer these to meet or exceed the original specs, and they use quality hose like Goodyear/Veyance/Contitech Galaxy in their assemblies.
All their hoses are pressure-tested for leaks before they go out, which is reassuring.
They've got this \QFP\ philosophy – Quality, Fit, and Price – aiming to make sure it fits right and works well.

To be sure it fits your car, you should add your vehicle's year, make, and model to Amazon's garage thing, or cross-reference with your old part.
Comes with an industry-leading warranty (length not specified, but they back it).

If your AC isn't cooling and you've found a leak or damage at one of these hoses, replacing it with this can get your cold air back.
Installation usually requires evacuating and recharging the AC system, so best left to a pro unless you're experienced.

Good option if you want OE-level quality without the dealer price tag.
Just make sure you get the right part number for your specific car.
