    70766 8CPBXREEL

    Product # 46572550

    Recommended for high-pressure hydraulic lines in longwall mining equipment and roof-support systems; petroleum-based or water emulsion fluids. Two wire braid hose with static and dynamic pressure ratings listed on the hose.

    • Recommended For: High-pressure hydraulic lines in longwall mining equipment and roof-support systems; petroleum-based or water emulsion fluids.
    • Couplings: MegaCrimp™ Couplings (-4, -6, -8, -12, -16 and -20) GSP (-24 and -32).
    • Dynamic working pressure per BCS174 means frequent pressure surges.
    • MegaTuff™ hose lasts up to 300 times longer than standard hose during hose-to-hose and hose-to-metal abrasion tests per ISO 6945 and offers superior ozone and weathering resistance.
    • Qualification testing requires 100,000 impulse cycles at 133% of the dynamic working pressure. Static working pressure means very little pressure surging.
    • BCS174 says that the internal hydraulic circuit of a roof support system represents an almost steady-state condition with little or no dynamic loading, and hoses consequently will tolerate higher ratings.
    • Determined by EN 853 2SN, it is the allowable working pressure under static load that approximates a 1:2.5 ratio to burst pressure.
    • This is based on the EN specification burst pressures and not the higher Gates minimum burst pressures.
    • Superior to SAE and ISO Specifications.
