    Frequently Asked Questions
    What is the maximum working pressure of the Jet Wash 4W hose?
    The Jet Wash 4W hose handles a maximum working pressure (MAX W.P.) of 828 bar (12,000 psi) across all available sizes, including 3/8", 1/2", and 3/4".
    How do Jet Wash 1W and Jet Wash 2W hoses differ in pressure ratings?
    Jet Wash 2W hoses offer higher pressure ratings than Jet Wash 1W. For example, a 1/4" Jet Wash 1W has a MAX W.P. of 275 bar (4,000 psi), while the 1/4" Jet Wash 2W supports up to 415 bar (6,000 psi).
    What sizes are available for the Jet Wash 1W hose series?
    The Jet Wash 1W series is available in nominal inner diameters (I.D.) of 1/4" (6.3 mm), 5/16" (8.0 mm), 3/8" (10.0 mm), and 1/2" (12.5 mm).
    What is the minimum bend radius (MIN B.R.) for the 1/2" Jet Wash 2W hose?
    The minimum bend radius for the 1/2" (12.5 mm) Jet Wash 2W hose is 180 mm, ensuring flexibility without restricting flow or damaging the hose structure.
    Does the weight of the hose increase with higher pressure ratings?
    Yes, hoses with higher pressure ratings generally weigh more due to additional reinforcement. For instance, the 3/8" Jet Wash 1W weighs 0.34 kg/m, the 2W weighs 0.49 kg/m, and the high-pressure 4W weighs 0.85 kg/m.
