🔹Product Overview

Cylinder Liner Seal Part No.AR70577 is an important sealing component for KTA19 diesel engines, widely used on excavators and heavy‑duty diesel machinery. It is installed between cylinder liner and engine block, effectively sealing cooling water channel to prevent coolant leakage. This cylinder liner seal solves typical failures such as coolant leakage, water entering lubricating oil and engine overheating caused by aging, hardening and cracking of original sealing ring. Every seal undergoes strict dimension inspection and compression resistance testing before independent packaging and delivery.

🔹Detailed Specifications

🔹Key Features & Advantages

• Premium composite rubber material, excellent heat‑resistance, coolant‑resistance and anti‑aging performance under long‑term engine working temperature.
