    85521 8M4K-MTFX50FT

    Product # 46574021

    Recommended for high-pressure hydraulic applications. Easy to route and to install in extremely tight areas. Meets or exceeds requirements of ISO 18752 Grade B, SAE 100R19, EN 857 2SC and ISO11237 R19. Recommended Couplings: GlobalSpiral™ Couplings, MegaCrimp™ Couplings (-4 to -12), Stainless Steel B Couplings (-4 through -8), Stainless Steel S Couplings (-10 to -16).

    • The optional MegaTuff™ cover 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.
    • The optional XtraTuff™ cover lasts up to 25 times longer than standard hose.
    • For use with GlobalSpiral™ Couplings [G20 Series], MegaCrimp™ Couplings [G25 Series], Stainless Steel Braid Couplings [G17 Series] or Stainless Steel Spiral Couplings [G18 Series].
    • Tested to 600,000 impulse cycles, 3 times the industry standard.
    • M4K hose is compatible with biodegradable hydraulic fluids like synthetic esters, polyglycols and vegetable oils as well as petroleum-based fluids.
    • Provides bend radius up to 1/3 of the SAE specification and greater flexibility for easier routing.
    • Meets Flame Resistance Acceptance Designation MSHA 2G.
