MINETUFF 4000 PSI is intended for very high pressure service with tight bends moving petroleum-based hydraulic fluids. Extraordinary flexibility, excellent bend radii properties, and exceptional impulse life, with over 1,000,000 impulse cycles at 250°F (121° C) and 133% of rated working pressure (at SAE 100 R12 conditions) when tested with appropriate hydraulic-interlock couplings.
Tube: Synthetic rubber and biodegradable fluids (oil resistant)
Cover: Synthetic rubber (0zone, abrasion & hydrocarbon resistant)
Reinforcement: Four high tensile steel spirals
Temperature Range: -40ºF to 250ºF (-40ºC to 121ºC)
