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 H EL is a PU suction & transport hose, medium duty, very flexible, electroconductive. It is medium heavy in weight, pressure resistant, with a black 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 26–254 mm, in 10 m, 15 m, 20 m, 25 m lengths.
Wall material: surface resistance R₀ < 10³ Ohm.
Note: ATEX / explosion-zone suitability must always be assessed for your specific installation by the operator.
