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 Master-PUR STEP is a PU film hose, crush-resistant, hardly inflammable acc. to DIN 4102 b1. It is very flexible and light in weight, moderately pressure resistant, with a tubing wall transparent with blue spiral wall.
Constructed as a film hose with attached support coil with a polyester polyurethane wall, it operates from -40 °C to +90 °C (peaks to 125 °C). Available in bore sizes from 51–160 mm, in 10 m, 15 m lengths.
Wall material: material is more abrasion resistant than comparable polyurethane according to DIN ISO 4649; flame retardant according to DIN 4102 B1.
Note: ATEX / explosion-zone suitability must always be assessed for your specific installation by the operator.
