Didn't even use it. The thermostat came with one even though it wasn't listed in the, "what's in the box" it's a seal, I'm sure it does its job. Can say it was the correct part.

great fit right out the wrapper. After removing the old gasket and placing the new one i added coolant and checked fore leaks. since its an OEM gasket there were no leaks as expected.... I would always buy ACDelco oem parts for my 2014 chevy silverado 1500 ltz 4x4... great buy and price
