Frequently Asked Questions (FAQ)
What do W.P. and B.P. stand for in the specification table?
W.P. stands for Working Pressure, which is the maximum pressure the hose is designed to operate under safely (measured in BAR). B.P. stands for Burst Pressure, which is the pressure at which the hose is expected to fail or rupture. In this spec sheet, the safety factor is 3:1 (36 BAR B.P. vs 12 BAR W.P.).
How does the "Layer" specification affect the hose performance?
The "Layer" column (e.g., 1S, 2S, 4S) indicates the reinforcement structure of the hose. More layers generally offer higher durability, structural integrity, and resistance to external hazards, even if the operating pressure (W.P.) remains constant at 12 BAR.
What are the standard lengths available for these hoses?
Hoses with an Inner Diameter (ID) of 1/2" and 5/8" are available in standard lengths of 100 meters. Hoses from 3/4" up to 5" ID are supplied in standard lengths of 61 meters.
What does the tolerance value (e.g., ±1 or ±1.5) on the Hose OD mean?
The tolerance value indicates the allowable variance in the outer diameter (OD) during manufacturing. For example, a 2" hose with an OD of 70±1.5 mm means the actual outer diameter can range between 68.5 mm and 71.5 mm.
Are these hoses suitable for high-pressure applications above 12 BAR?
No, the rated Working Pressure (W.P.) for these hoses is 12 BAR (with one exception showing 2 BAR). Operating the hoses above their rated W.P. is not recommended, as it compromises safety margins and reduces the lifespan of the hose.
