A2-08 Shaft Seal for 4NFCY 6NFCY Bus Air Conditioner Compressor

The A2-08 is a universal compressor shaft seal specially engineered for both 4NFCY and 6NFCY series heavy-duty bus air conditioner compressors. As a core sealing component mounted on the compressor crankshaft, it effectively blocks refrigerant and lubricating oil leakage from the shaft gap, directly maintaining the cooling efficiency and long-term stable operation of the AC system.

Crafted from high-grade refrigerant-resistant and wear-resistant composite materials, this shaft seal features excellent high & low temperature resistance and anti-aging performance. It maintains stable sealing effect under long-term high-speed rotation and extreme working conditions, effectively reducing refrigerant loss, lowering maintenance frequency and extending the compressor overhaul cycle. Its universal compatibility with two compressor models also helps reduce inventory pressure for fleet operators and repair shops.

Backed by 39 years of professional experience in the bus HVAC industry, TCHAIN provides 100% quality-inspected shaft seals that are fully compatible with most 6-14m diesel buses, school buses, shuttle buses and long-distance coaches equipped with 4NFCY or 6NFCY series compressors. We offer competitive wholesale prices, comprehensive technical support and fast global delivery to minimize your fleet downtime.
