Description
What does a compressor piston and ring do?
This compressor piston and ring set serves as a critical component within the pneumatic air brake compressor system. It is engineered to maintain precise compression cycles and ensure the structural integrity of the air delivery process under heavy-duty operating conditions.Compatible vehicles and engine systems
This specific kit is compatible with Mercedes-Benz and MAN heavy commercial vehicles. It is also suitable for use in systems designed for Deutz engines and is compatible with WABCO systems. When performing an overhaul, it is vital to ensure the piston diameter matches the cylinder liner requirements.Installation and maintenance guidance
For professional installation, technicians should verify the groove clearances and end gaps according to the service manual. Ensuring the piston and rings are seated correctly prevents air leakage and maintains consistent pressure. This assembly is designed to withstand high temperatures and continuous mechanical stress.Selection and sizing advice
During maintenance, it is recommended to inspect the cylinder liner for wear. If the liner has been machined, an oversize ring set may be required instead of this standard diameter version. Consult your authorized distributor for fitment guidance.Related Products

FAQ
What is the function of the compressor piston and ring?
The piston moves within the cylinder to compress air, while the rings provide a seal against the cylinder wall to prevent pressure loss in the pneumatic system.
Which vehicle brands are these components compatible with?
This specific set is designed for Mercedes-Benz and MAN heavy commercial vehicles, and is also compatible with WABCO systems.
Can I use a standard diameter ring if my liner has been machined?
No, if the cylinder liner has been rebored or honed, you must use an oversize ring set rather than this standard Ø90,00mm version.
How can I ensure correct fitment during installation?
Technicians should verify the piston diameter and check that ring thickness matches the groove height to prevent rattling or binding.
