Material

spiral: spring steel wire

wall: pure polyester polyurethane (acc. to
DIN ISO 4649 more abrasion-resistant in
comparison to polyether polyurethane)
wall thickness between spirals approx. 2.1 mm

Applications

● Protective Hose against mechanical wear

● Special Transport Hose for the delivery of
abrasive media

● Lightweight, flexible working hose

Properties

● highly abrasion-resistant

● good chemical resistance

● generally good UV and ozone resistance

● oil/petroleum-proof

● free of halogens and plasticizers

● gas-tight

● small bending radii

● high tensile strength

● mostly smooth inner lining

● optimum flow characteristics

● acc. to TRBS 2153 (Zone 20) for nonflammble
dust/bulk solids for conducting
electrostatic charges when earthed at both
ends of the spiral

● microbe-resistant

● antistatic, surface resistance < 109 Ohm

● reinforced version of standard version
Master-PUR HÜ

Temperature Range

● –40°C to +90°C

● peaks to +125°C
