Air Compressor Aftercooler Metal Flexible Tube Hose fit Atlas Copco GA90
The Metal Flexible Hose (P/N 1092300928) is a precision-engineered stainless steel connection for use in aftercooler systems on Atlas Copco air compressors. It provides a reliable and flexible air path between the compressor discharge and the aftercooler, accommodating thermal expansion, vibration, and alignment tolerances. Meeting original equipment manufacturer (OEM) standards for durability and efficiency, the hose ensures stable airflow and safe system operation under continuous high-temperature and high-pressure conditions.

The aftercooler section of a rotary screw air compressor operates under severe thermal and pressure loads. The 1092300928 flexible metal hose is designed to connect the exhaust port and cooling components while maintaining structural integrity and airflow efficiency. It prevents vibration transmission between components, protects rigid piping from thermal stress, and improves the reliability of the entire air cooling circuit.
The hose's corrugated stainless steel core provides flexibility and vibration dampening properties, while the braided outer jacket provides mechanical protection against expansion and pressure fluctuations. As a result, the hose is durable and leak-proof, maintaining stability even under the high loads and cyclic conditions common in industrial compressor systems.
Material & Construction
- Material Composition: High-grade stainless steel, corrosion- and fatigue-resistant.
- Internal Construction: A corrugated core design ensures flexibility without compromising internal flow.
- Reinforcement: Tightly woven stainless steel braid prevents deformation under dynamic pressure.
- End Fittings: Precision-welded or crimped stainless steel fittings, compatible with Atlas Copco OEM connections.
- Operating Pressure: Designed to withstand the high-pressure discharge of screw compressors.
- Testing Standards: 100% hydrostatically tested and vacuum-tested to ensure leak-free performance.
Function & Benefits
The flexible metal hose (1092300928) for Atlas Copco aftercoolers offers the following operational advantages:
- Thermal Expansion Compensation: Absorbs thermally induced expansion between the compressor discharge port and the cooler assembly.
- Vibration Isolation: Reduces mechanical stress and noise transfer between rigid piping.
- Pressure Stability: Maintains constant pressure with minimal pulsation, ensuring consistent cooling efficiency.
- Corrosion Resistance: The stainless steel body resists oxidation and moisture.
- Long Service Life: Provides exceptional durability under thermal cycling, pressure fluctuations, and continuous operating conditions.
Unlike conventional rubber or composite hoses, the stainless steel construction maintains mechanical strength and sealing accuracy even after prolonged exposure to high-temperature compressed air and oil vapor.
Engineering & Manufacturing Process
Every 1092300928 flexible hose is manufactured under strict process control:
- Precision corrugation of stainless-steel tubing for uniform wall thickness.
- High-strength braiding using automated weaving machines.
- TIG welding of end fittings to ensure consistent sealing and fatigue resistance.
- Pressure endurance test under simulated operating conditions.
- Final dimensional verification and visual inspection to confirm compliance with OEM specifications.
This combination of advanced forming and quality assurance guarantees excellent reliability and fitment consistency across batches.
Installation & Maintenance Notes
- Ensure that hoses are installed without twisting or excessive bending, and that their minimum bend radius is not exceeded.
- Use appropriate brackets to minimize vibration loads on the fittings.
- Before installation, check that seals or gaskets are properly installed and intact.
- Perform a leak check after the system is pressurized.
- Regularly inspect the hose surface for corrosion, wear marks, or fatigue cracks—replace any defects immediately.
Proper installation and maintenance help maintain optimal cooling performance and extend the overall life of the compressor.

Maintenance Advantages
Replacing worn aftercooler hoses is crucial to maintaining proper air cooling efficiency and system reliability. Hose damage can cause:
- Air leaks and pressure loss
- Degraded aftercooling performance
- Increased exhaust gas temperatures
- Overheat alarms can cause compressor shutdowns
Using the 1092300928 stainless steel flexible hose, operators can restore full cooling performance, minimize unplanned downtime, and ensure long-term, reliable compressor system operation.
