Product Overview

O‑ring Seal Part No.3883963 is an essential rubber sealing component for cumm-ins ISF2.8 and ISF3.8 diesel engines, widely fitted for excavators, light commercial vehicles and construction equipment. It is assembled on engine pipe joints, assembly gaps and cooling‑lubrication circuits, used to seal clearances and prevent leakage of engine oil, diesel fuel and coolant, meanwhile blocking outside dust and impurities from entering engine inner structures. This replacement o‑ring effectively solves medium leakage issues caused by original o‑ring aging, cracking, hardening and permanent deformation under high‑temperature and oil‑soaked working conditions. Each o‑ring seal will go through dimension checking, material performance test and appearance defect inspection before delivery.
