Product Overview & Key Features
PVC Layflat Hose is a collapsible water transfer solution designed for agricultural, construction, and industrial applications. With a working pressure range of 4-8 bar, these hoses offer reliable performance for medium-pressure water transfer needs. Key characteristics include:
Collapsible design saves up to 80% storage space when not in use
Available in diameters from 1" to 8" (25mm to 207mm)
Standard working pressure of 4-8 bar (58-116 psi)
Burst pressure typically 3 times working pressure
Manufactured in blue or black UV-resistant PVC material
Common lengths of 25m, 50m, and 100m
The 4-8 bar pressure rating makes these hoses suitable for pump-assisted irrigation systems and other applications requiring moderate pressure resistance.
