High-Performance 20 Bar Air Hose Assemblies for Demanding Job Sites
In harsh industrial, construction, and mining operations, continuous air tool functionality relies heavily on stable pneumatic transfer lines. Standard utility hoses often fail under oil-laden air or sudden pressure surges. To solve these field challenges, Shanghai PME Industrial offers factory-crimped heavy duty 1/2 air hose 20 bar assemblies designed to handle severe utility air transfer requirements.

Engineered Rubber Construction
Built with high-grade synthetic materials, this hose features a multi-layer design optimized for reliability across extreme working environments:
- Inner Core: Black synthetic Nitrile Rubber (NBR), formulated to handle oil mist carried over from industrial air compressors.
- Reinforcement: Braided high-tensile textile yarn providing a robust 20 Bar (300 PSI) working pressure and a 3:1 burst safety factor.
- Outer Shield: High-visibility yellow synthetic compound for easy identification on busy worksites.
- Thermal Endurance: Rated for operating temperatures ranging from -30°C to +100°C (-22°F to +212°F).

Pre-Crimped Chicago Coupling & CS Ferrule System
Connection integrity is critical under 20 Bar operating pressures. Instead of relying on manual worm-gear clamps, PME Industrial utilizes a precision factory-crimping process. Each assembly comes pre-fitted with 1/2" ductile iron Chicago couplings secured by heavy-duty Carbon Steel (CS) ferrules. This mechanical interlocking crimp ensures a permanent, leak-free connection capable of handling severe pressure surges without fitting blow-off risks.
