2600 130 300 Compressor Piston for Detroit Diesel

What does a compressor piston do?

This compressor piston is a critical component within the air brake compressor assembly, responsible for maintaining the necessary pressure levels for pneumatic braking systems. Manufactured with heavy-duty grade materials, this part ensures stable air output and long-term durability under intense mechanical stress.

Compatible vehicle models and engines

This component is compatible with Detroit Diesel engines such as the DD13, DD15, DD16, and 60 Series. It is widely fitted to heavy commercial vehicles including Freightliner models like Cascadia and Columbia, Western Star series such as 4900 and 5700XE, and International 9400 or 49X units. It is also used in Peterbilt, Kenworth, and Sterling vehicles equipped with these engine series.

Maintenance and installation guidance

During maintenance or overhaul, technicians should inspect the cylinder liner to determine if a single piston is sufficient or if a complete piston-and-ring set is required. Proper installation ensures optimal air-tight integration within the compressor assembly. Consult your authorized distributor for fitment verification.

Troubleshooting compression loss

When diagnosing loss of air pressure, inspecting the piston and rings for wear is a standard procedure. Replacing worn components helps restore the compression function of the unit without requiring a full compressor replacement.
