QWhat do I.D. and O.D. mean in the specification table?
I.D. stands for Inner Diameter, which is the measurement of the inside space of the hose (available in millimeters and inches). O.D. stands for Outer Diameter, which measures the entire span across the hose exterior including the walls.
QWhat is the significance of the "PLY" rating?
The PLY rating represents the number of reinforcement layers within the hose. A higher ply rating (such as 4-ply for larger sizes) provides structural strength to handle specific working pressures and increases durability.
QHow does the Maximum Working Pressure (MAX WP) vary by size?
Smaller hose sizes (I.D. 6mm to 12mm) support a higher working pressure of 20 bar (290 psi). Larger sizes (I.D. 16mm to 102mm) are rated for a maximum working pressure of 12 bar (174 psi) to ensure safe operations.
QWhat standard lengths are these hoses available in?
Hoses with inner diameters up to 12mm (1/2") come in standard lengths of 50 meters. Hoses with inner diameters of 16mm (5/8") and above are available in 20-meter or 40-meter options.
QAre there different cover options available for these hoses?
Yes, depending on the specific model and size requirements, hoses can be produced with either a clothed (wrapped texture) or smooth cover finish to suit different application environments.
