Heavy Duty 1/2″ Air Hose Assembly (20 Bar / 300 PSI) with Chicago Coupling & CS Ferrule
In heavy industrial applications, construction sites, and outdoor mining projects across Central Asia, reliable pneumatics demand rugged fluid transfer components. Shanghai PME Industrial supplies premium heavy duty 1/2 air hose 20 bar assemblies specifically engineered for continuous delivery of compressed air, oil mist, and general utility fluids. Supplied in standard 50-meter coil lengths, this robust hose is factory-crimped with universal 1/2″ iron Chicago couplings and heavy-duty carbon steel (CS) ferrules to ensure leak-proof 300 PSI air delivery and prevent blow-offs under severe pressure surges.

Technical Breakdown & Selection Guide
When selecting a 20 bar compressed air hose for industrial air tools, compressors, and pneumatic machinery, material compatibility and connection security are critical:
1. Multi-Layer Hose Structural Design
- Inner Tube: Smooth black synthetic nitrile rubber (NBR).
- Reinforcement Layer: High-tension synthetic textile yarn engineered to withstand continuous working pressures up to 20 Bar (300 PSI) with a minimum 3:1 safety burst ratio.
- Outer Cover: Bright yellow nitrile rubber compound.
2. Temperature & Extreme Environmental Endurance
Operating smoothly across extreme temperature ranges from -30°C to +100°C.
3. Connection Security: Chicago Coupling + CS Ferrule
A cs ferrule air hose assembly provides a permanent mechanical crimp connection, ensuring leak-proof air transfer at 300 PSI.
