Refurbished products may have cosmetic imperfections, such as:

• Surface scratches

• Discoloration

• Signs of previous installation or handling

These imperfections are visual only and do not affect performance, durability, or fit.

✔️ 100% Money-Back Guarantee still applies—if we cannot resolve your leak through our troubleshooting process.
