Frequently Asked Questions
Q: What is the maximum working pressure for these hoses?
The maximum working pressure varies by hose size. For smaller inner diameters (6mm to 12mm), the maximum working pressure is 20 bar (290 psi). For larger sizes ranging from 16mm to 102mm, the working pressure is rated at 12 bar (174 psi).
Q: What reinforcement structure (PLY) options are available?
Depending on the size, the hoses are designed with either a 2-ply reinforcement structure (for sizes 6mm up to 27mm I.D.) or a stronger 4-ply reinforcement structure (for larger sizes from 32mm up to 102mm I.D.) to ensure high durability and pressure resistance.
Q: What are the standard lengths available for purchase?
Hoses with an inner diameter of 6mm to 12mm are supplied in standard lengths of 50 meters. Hoses with an I.D. of 16mm and above are available in lengths of either 20 meters or 40 meters.
Q: Do you offer different hose outer diameters (O.D.) for the same inner diameter (I.D.)?
Generally, each inner diameter size is engineered with a standard outer diameter to optimize safety and performance. For example, the 3/4" I.D. hose is available in two configurations (18mm and 20mm I.D.), both featuring an O.D. of 26.8mm.
Q: What size range is covered in this specification table?
The specification covers a wide range of sizes starting from a minimum inner diameter of 6mm (1/4 inch) up to a maximum of 102mm (4 inches) to support various industrial applications.
