Wear Sleeve

The Cummins Wear Sleeve (Part Number: 190397) is a genuine OEM cylindrical metal sleeve designed to protect and restore shaft surfaces in Cummins engines. It serves as a wear-resistant barrier, reducing friction and preventing damage to the shaft caused by seals or environmental factors. Manufactured from high-quality steel, this sleeve ensures precise fitment, durability, and extended service life for components in heavy-duty diesel applications such as Cummins 855, N14, K, and QSK series engines.
