1、Ambient Working Pressure: Clear air hose has an ambient working pressure of 10kg/cm² or 149.5psi, an ultimate working pressure of 12kg/cm² or 179.4psi, and a tensile strength of 400kg/cm² or 5980psi. 2、Connection Process: The transparent air hose has a tear strength of 110kg/cm² or 1644.5psi, abrasion resistance of 35mg, and is also oil and electrical resistant. Connect the hose to an air compressor and then connect the other end of the hose to a pneumatic air tool, such as a grinder, or inflatable fitting. 3、High Strength Internal Reinforcement Layer: This high performance flexible hose is designed to resist twisting, kinking, scratching and bending. The hose has an abrasion resistant outer layer and a high strength internal reinforcement layer that prevents the hose from elongating under pressure. 4、Wide Application: The air hose is suitable for use in automotive repair, body repair, construction sites, as well as homes and garages. 5、PU Material: The air hose is made of PU material, which is strong, very flexible and lighter than most hoses. Remains flexible even at extremely hot or cold temperatures of ‑20°C to +60°C (‑4°F to 140°F).
