Polyurethane Ducting Hose

agricultureconstructionindustrialmarineminingrail

High flexibility Polyurethane ducting hose, reinforced with a semi-rigid crush resistant PVC helix. CPU ducting is manufactured from polyether polyurethane offering excellent resistance to hydrolysis. It is tough, flexible and extremely durable under normal operating conditions. The cross section is maintained even when highly flexed. Minimum frictional loss is achieved by the smooth bore.

(i) Maximum working pressure is based on a factor of safety of 3:1 on short term burst pressure at 20°C. If the temperature increases, please refer to the temperature pressure charts.
(ii) Lengths detailed above are as standard, however variations may be available subject to minimum order quantities. Weights are approximate dependent upon working tolerance and
density of materials.
(iii) Bending diameter information is intended as a guide to the minimum bend radius at 20°C ambient temperature without restricting the bore. It does not mean that the hose cannot be
bent below the given dimensions but restriction is likely to occur.
