Product Description

Product Description

Tube: Oil resistant synthetic rubber
Reinforcement: One high tensile steel wire braided layer.
Cover: Abrasion and weather resistant synthetic rubber, MSHA IC-405/01 approved.  
Temperature:-40ºC to +125ºC
Safety factor:4:1

Our EN 856 4SP and 4SH spiral hydraulic hoses are the ultimate solution for heavy-duty applications requiring extreme pressure resistance and high impulse durability. Unlike braided hoses, the spiral construction ensures superior structural integrity under the toughest working conditions.

Technical Features:

Reinforcement: 4 layers of high-tensile steel wire spiraled in alternating directions.

Inner Tube: Oil-resistant synthetic rubber (NBR) for excellent compatibility with hydraulic fluids.

Outer Cover: Superior abrasion, ozone, and weather-resistant synthetic rubber (available in smooth or wrapped finish).

Safety Factor: 4:1 (Burst pressure to working pressure).

Temperature Range: -40°C to +100°C (-40°F to +212°F).
