Hi, I'm Carrie Xu. I work directly with overseas equipment dealers, repair workshops and contractors looking for CAT and SEM spare parts.
Instead of communicating through multiple departments, you will communicate directly with me from inquiry to quotation. If you already have the machine model, serial number, part number or photos, feel free to contact me on WhatsApp.
Whether you need a single seal kit or a full container load — we respond within 24 hours.
