A2-07 F400Y Bus Air Conditioner Compressor Shaft Seal

The A2-07 F400Y is a precision-engineered compressor shaft seal designed exclusively for F400Y series heavy-duty bus air conditioner compressors. As a critical sealing component installed on the compressor crankshaft, it prevents refrigerant and lubricating oil leakage from the shaft gap, directly ensuring the operating efficiency and service life of the entire AC system.

Manufactured from high-grade refrigerant-resistant and wear-resistant composite materials, this shaft seal features excellent high and low temperature resistance, aging resistance and reliable sealing performance. It maintains stable sealing effect under long-term high-speed rotation and extreme temperature conditions, effectively reducing refrigerant loss, lowering maintenance frequency and extending the overhaul cycle of the compressor.

With 39 years of professional experience in the bus HVAC industry, TCHAIN supplies 100% quality-tested compressor shaft seals that are fully compatible with most 6-14m diesel buses, school buses, shuttle buses and long-distance coaches equipped with F400Y series compressors. We provide competitive wholesale prices, comprehensive technical support and fast global delivery to minimize your fleet maintenance downtime.
