Application and limits

Application: Layflat delivery hose for concrete, sand, gravel and other dry abrasive materials at up to 4 bar.
Features: Lays flat when empty, conductive inner tube
Limits: Operating temperature from −40 to +70 °C.
Working pressure depends on the inner diameter — see the table. Burst pressure is a reference value, not a working pressure.
Layflat hoses are not suitable for suction.
