Seal your hose properly — sized automatically to match the bore you selected. We’ve added 2 — one for each end of the hose. Adjust if you need more or fewer.
The Polderflex PUR is a PU suction & transport hose, extremely pressure and vacuum resistant, with smooth inner and outer walls. It is moderately flexible and heavy in weight, with a transparent wall.
Constructed as a profile extruded hose with metal spiral with a polyester polyurethane wall, it operates from -40 °C to +90 °C (peaks to 125 °C). Available in bore sizes from 32–76 mm, in 10 m lengths.
Wall material: material is more abrasion resistant than comparable polyurethane according to DIN ISO 4649.
Note: ATEX / explosion-zone suitability must always be assessed for your specific installation by the operator.
