What is the difference between original car glass and replacement glass?

[DiAndrew]

There are differences in the sealing between original car glass and replacement glass. If there are installation issues with a replaced windshield, it may lead to water leakage during later use. In severe cases, driving the vehicle could cause the windshield to detach, resulting in an accident, which is extremely dangerous. Below are specific methods to check whether the glass has been replaced: 1. Check the manufacturer: Examine the manufacturer code on the glass to identify which company produced it. Generally, car manufacturers purchase glass in bulk and do not use too many brands or the same brand from different production locations. 2. Check the production date of the glass: If there is a significant difference in the production dates of the glass pieces on a single vehicle, it may indicate that the car has been refurbished or the glass has been replaced later. 3. Check the glass label: If the car glass has been replaced, the new glass label will differ significantly from the original factory label.
