GlobalSpiral couplings are specially engineered to provide superior performance for extreme high-pressure, high-impulse spiral-wire hydraulic hose applications. They can be used with all Gates MegaSys four- and six-spiral wire hose up to 6,000 psi. When used with 2-wire ferrules, GlobalSpiral couplings can also be crimped on Gates wire-braid hoses. The innovative, two-piece, no-skive design reduces assembly time, labor, fabrication errors and contamination of the ?uid power system. Consult eCrimp for wire braid types and sizes. MGS Couplings for use with MC4-20 Crimper Only.
