3094155 Volvo F7 TD70 Compatible Compressor Ring

What does a compressor ring do?

This compressor ring is a critical component within the air brake compressor assembly, designed to maintain pressure and ensure efficient pneumatic operation. Manufactured from high-strength components, these rings are engineered to withstand the intense thermal and mechanical stresses found in heavy commercial vehicle braking systems.

Vehicle and engine compatibility

This specific component is compatible with Volvo F7 trucks equipped with TD70 engines. It is essential for maintaining the sealing integrity within the cylinder during the compression cycle. When performing an overhaul, it is recommended to verify the piston diameter and groove dimensions to ensure a precise fit.

Installation and maintenance guidance

For successful installation, technicians should ensure that the ring thickness matches the piston groove height to prevent rattling or binding. It is vital to check the end-gap clearance according to the service manual. For optimal results during maintenance, replacing rings as a complete set is advised to ensure uniform wear across all grooves.

Selection advice

Always confirm the engine specifications and compressor type before installation to avoid mismatching standard or oversize components.
