7000 704 100 Piston & Ring for Air Brake Compressors

What does a compressor piston and ring do?

Air brake compressor piston and ring sets are essential components used to maintain the air pressure required for braking systems in heavy commercial vehicles. These parts work within the compressor cylinder to facilitate the compression of air, ensuring consistent pneumatic pressure for the vehicle's braking function.

Vehicle and engine compatibility

These high-strength components are compatible with various heavy commercial vehicle models, including Kenworth T660, Peterbilt 379, and Freightliner Columbia, particularly those equipped with Caterpillar C15, C16, or 3176 engines. They are also fitted to International 9900I, Western Star 6900, and Mack Titan trucks. This ensures reliable performance across diverse heavy-duty fleets.

Installation and maintenance guidance

When performing maintenance, technicians should inspect the cylinder liner for scoring to determine if a single piston or a full kit is required. Proper installation involves verifying the piston diameter and pin bore against the manufacturer's service manual to ensure a precise fit within the compressor assembly.

Maintenance and troubleshooting

Regular inspection of the rings can help prevent air leakage and maintain optimal compression levels within the pneumatic system. Consult your authorized distributor to ensure correct fitment for your specific engine model.
