In Atlas Copco GA-series compressors, the aftercooler plays a vital role in cooling compressed air before it enters the downstream system. The 1622378700 metal flexible hose serves as the high-durability conduit connecting the compressor outlet to the aftercooler unit. It must withstand intense pulsating pressure, thermal expansion, and vibration generated during compressor operation.
Manufactured from high-strength stainless steel with a multilayer corrugated structure, this hose provides superior flexibility while maintaining mechanical strength. Its design minimizes stress on rigid piping and ensures a secure, leak-free connection between components.
Key Features & Advantages
- High-Quality Stainless Steel Construction: Constructed from corrosion-resistant stainless steel, it ensures exceptional durability in humid or high-temperature compressor environments.
- High-Pressure and High-Temperature Resistant: Designed to withstand operating pressures up to 20 bar and temperatures exceeding 250°C with consistent performance.
- Flexible Bellows Design: Precision-formed bellows absorb vibration and thermal expansion, protecting adjacent components from mechanical stress.
- Leak-Free Performance: TIG-welded ends and reinforced braid prevent air leaks under dynamic loads.
- Perfect OEM Fit: Designed to precisely match the dimensions and connection threads of Atlas Copco GA75 and GA90 compressors, enabling easy replacement.
Structure and Material Details
- Inner Tube:
Corrugated stainless steel for smooth airflow and resistance to fatigue cracking. - Outer Braid:
Interwoven stainless-steel mesh enhances pressure resistance and prevents expansion under high load. - End Fittings:
CNC-machined connectors ensure precision alignment and reliable sealing. - Weld Quality:
Argon arc welding technology ensures strong and uniform joints, extending service life.
Each hose is pressure-tested and helium leak-checked to guarantee perfect integrity before packaging.
Function in Compressor System
When the GA75 or GA90 compressor discharges high-temperature compressed air, the flexible hose channels it to the aftercooler, where the air temperature is reduced. During this process, the hose must accommodate both thermal expansion from heat and mechanical vibration from the motor and air-end.
A standard rigid pipe would eventually fatigue and crack under these conditions, but the flexible metal hose compensates for the movement, reducing mechanical stress and preventing system leaks.
Applications
- Atlas Copco GA75 / GA90 screw air compressors
- Aftercooler and intercooler air transfer systems
- Replacement for worn or cracked OEM hoses
- Industrial compressed air systems operating under vibration or high temperature
This model is also suitable for use in other Atlas Copco GA series compressors that share the same discharge line configuration.
Quality & Performance Testing
Each 1622378700 metal flexible hose undergoes the following quality inspections:
- Hydrostatic pressure testing to verify burst resistance
- Helium leak detection to ensure air-tightness
- Flex fatigue testing simulating thousands of operation cycles
- Dimensional and thread inspection for precise OEM compatibility
- Testing ensures every hose maintains OEM-level reliability under real operating conditions.
Installation Recommendations
- Before installation, ensure the connecting flanges and threads are clean.
- Avoid excessive torqueing or bending beyond the recommended radius.
- Check the alignment of the compressor outlet and aftercooler ports to reduce mechanical strain.
- Perform a pressure test after installation to confirm sealing performance.
Proper installation extends service life and maintains the mechanical integrity of connected components.
