What is the difference between Jet Wash 1W, 2W, and 4W hoses?
The designations 1W, 2W, and 4W represent the number of steel wire reinforcement layers inside the hose. More wire layers increase the hose's pressure capability. For example, a 3/8" 1W hose handles up to 4,000 psi, a 2W hose handles 6,000 psi, and a 4W hose handles up to 12,000 psi.
What is the maximum working pressure for the Jet Wash 4W hose?
All listed sizes of the Jet Wash 4W hose (3/8", 1/2", and 3/4") support a maximum working pressure of 828 bar (12,000 psi) with a minimum burst pressure safety rating of 2,070 bar (30,000 psi).
How does the minimum bend radius change across these models?
The minimum bend radius increases with hose diameter and reinforcement layers. For instance, the highly flexible 1/4" Jet Wash 1W has a bend radius of 100 mm, whereas the heavy-duty 3/4" Jet Wash 4W requires a minimum bend radius of 241 mm.
What is the safety factor ratio between working pressure and burst pressure?
These Jet Wash hoses feature a 3:1 safety factor. For example, the Jet Wash 1W 1/4" hose has a maximum working pressure of 4,000 psi and a minimum burst pressure of 12,000 psi.
Which hose size offers the lowest weight for easier handling?
The Jet Wash 1W 1/4" (6.3 mm metric I.D.) hose is the lightest option, weighing only 0.23 kg/m, making it ideal for standard pressure washing applications where mobility is key.
