1697282 Volvo NL12 D12A Piston and Ring Kit

What does a compressor piston do?

This compressor piston and ring assembly is a critical component within the pneumatic air brake compressor system, responsible for maintaining the necessary compression ratios required for braking performance. Manufactured using high-strength components, these parts are designed to withstand the high-pressure environment and thermal stresses encountered during continuous operation in heavy commercial vehicle applications.

Vehicle and engine compatibility

This specific kit is designed for use in Volvo NL12 trucks equipped with D12A engines. It serves as a reliable replacement to restore optimal air compression efficiency. The assembly is compatible with Volvo systems and is engineered to meet the rigorous demands of professional workshop maintenance.

Installation and maintenance guidance

When performing a repair, technicians should verify the piston diameter and groove condition. This kit features a standard 75.00mm diameter to ensure precise fitment within the cylinder liner. Proper installation ensures the integrity of the sealing system and prevents air leakage, maintaining stable system pressure.

System performance and selection

Regular inspection of the piston and rings during scheduled maintenance can prevent larger system failures. Always verify that the replacement components match the existing cylinder dimensions to ensure seamless integration into the compressor assembly.
