Spiral Wire Hydraulic Hoses

Gates® EFG6K Spiral Wire Hose: 420 bar

EFG6K Spiral Wire Hose: 420 bar

Recommended for extremely high-pressure, high-impulse applications such as hydrostatic transmissions. EFG6K is designed to meet or exceed all requirements of the SAE 100R15 specification and the performance requirements of EN 856 4SP (-6, -8, -10 and -12), EN 856 4SH (-12, -16 and -20) and ISO 3862 Type R15 (-6, -8, -10, -12, -16, -24). 12EFG6K meets ISO 18752 Class D. Recommended couplings: GlobalSpiral™ couplings, GlobalSpiral™ MAX pressure couplings, stainless steel S couplings (-6 to -20).
