GlobalSpiral™ Couplings


GlobalSpiral Couplings

Provides Inventory Reduction with No-Skive Convenience

More than five years of engineering and testing went into the GlobalSpiral (GS) coupling design. In performance testing required by Gates OEM customers, GS couplings surpassed one million impulse cycles at +250°F without stress cracks or failures. Both the stem and ferrule are machined from solid, unleaded steel bar stock for maximum strength. This enables GS couplings to handle working pressures up to 8,000 psi. The no-skive ferrule eliminates the need for skiving equipment, as well as odors and dust created while removing the protective outer cover from the hose. Ferrules that require skiving are subject to blow-offs when skived improperly. Blow-offs and weeping at the hose/coupling interface also can result from failure to fully insert the stem during assembly. With the two-piece design of the GS coupling, it is possible to pull the ferrule down and check for full stem insertion.

Fewer Part Numbers

The GS coupling is designed to work with existing Gates hoses and crimpers, thus minimizing inventory requirements. In fact, GS stems and ferrules can result in one-third fewer part numbers for as much as a 30 percent cost savings. This estimate is based on the fact that other manufacturers require at least two, or sometimes three different types of couplings to handle their four- and six-spiral wire hose lines.

Thread Configurations

The GS coupling is available in more than 30 thread configurations including SAE, DIN, British Standard Pipe, Komatsu-Style and JIS. In addition, GlobalSpiral flanges feature a solid, no-braze construction to provide extra reliability. GlobalSpiral FJX and FFORX stems have a machined swivel nut that passes a full 4:1 burst safety factor. GlobalSpiral couplings are available in 3/8-inch to 2-inch sizes.
