Product Overview

O‑ring Seal Part No.3037537 is a critical rubber sealing component for cumm-ins KTA19, KTA38, KTA50 diesel engines, widely applied for excavators, marine vessels and heavy‑duty industrial machinery. It is installed on engine oil circuits, cooling passages and assembly mating surfaces, used for gap sealing to prevent leakage of engine oil, fuel and coolant, and prevent external dust and impurities from invading internal engine components. This replacement o‑ring solves fluid leakage failure caused by original seal aging, cracking, hardening and permanent deformation under high‑temperature, high‑pressure and vibration working environment. Every o‑ring seal passes dimension inspection, material performance test and appearance defect check before shipment.
