What does a compressor piston and ring do?

This compressor piston and ring set is engineered to restore the efficiency of pneumatic brake systems. Designed for heavy-duty applications, these components ensure reliable air compression by maintaining precise tolerances within the cylinder, which is critical for the braking performance of heavy commercial vehicles.

Compatible Renault Trucks models and engines

This specific kit is compatible with Renault Trucks KERAX models equipped with DXi engines, including variants such as the 330.26, 460.26, and 520.33. It serves as a high-strength replacement component for the internal reciprocating assembly of the air brake compressor.

Installation and maintenance guidance

When performing maintenance or an overhaul, technicians should verify that the piston diameter and ring groove arrangement match the existing assembly exactly. Proper installation requires checking ring end gaps and groove clearances according to the manufacturer's service manual to prevent binding or loss of compression.

Troubleshooting and selection
