This is a connector for the seat control valve air pipe, essential for the pneumatic system that adjusts the driver's seat in Volvo trucks. It ensures a secure and leak-free connection, maintaining proper air pressure for seat functions, unlike a cracked or loose connector that would cause air leaks. Operators may notice the seat not adjusting correctly, a loss of air pressure, or an audible air leak.
Always verify with serial number before ordering.

Flush hydraulic lines before fitting new components. Use only manufacturer-specified hydraulic fluid. Check O-rings and backup rings for correct orientation. Bleed air from system after installation.
Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.
The initial symptom of a faulty connector is often a slow or unresponsive seat adjustment, or a faint hissing sound of escaping air. If left unaddressed, the air pressure loss will worsen, leading to complete failure of seat adjustment functions. This can cause driver discomfort and potential ergonomic issues during long hauls.
Ensure the air line is clean and free of debris before inserting it into the new connector. Do not force the connection; it should seat firmly with minimal effort.
Inspect the associated air lines and the seat control valve itself for any signs of damage or wear when replacing this connector.
