An Atlas Copco Hose Assembly is a factory-engineered, high-pressure flexible conduit designed specifically for the GA, GX, and GR series rotary screw compressors. These assemblies consist of a multi-layered, reinforced hose body and permanently crimped end-fittings, ensuring a leak-proof connection for transporting hot Roto-Inject or Roto-Xtend lubricants and high-pressure compressed air.Because Atlas Copco compressors operate at high temperatures (up to $110$°C) and experience constant vibration, these assemblies are built to be significantly more durable than standard hydraulic hoses. Using a genuine Atlas Copco hose assembly prevents "liner flaking"—a common issue with aftermarket hoses where degraded rubber particles enter the air-end and cause bearing failure
