SOLID, LEAK-FREE COUPLINGS
The majority of hydraulic hose failures occur at the couplings due to blow-offs or leaks. Gates has designed and engineered innovative, robust couplings for MegaSys hose that provide connections you can count on for superior performance – guaranteed.
MegaCrimp® Couplings G25
> Robust “bite-the-wire” crimp
> Low profile
> Full-stem insertion
> Full-length crimp
> Simplifies inventory management
> Environmentally-friendly TuffCoat™ plating for 700 percent better corrosion resistance
MegaCrimp - The Versatile “No-Weep” Coupling with the Patented “C” Insert
It’s what’s inside the pre-assembled MegaCrimp coupling that gives it world-class, leak-proof performance. It is designed with a patented “C” insert, attached to the ferrule, that accommodates hose of different constructions and wall thicknesses. The insert’s design ensures crimping forces are evenly distributed to form a concentric seal. The “C” insert simplifies inventory requirements since one MegaCrimp coupling size can accommodate various hose outside diameters, on both one- and two-wire braid hydraulic hose.
TUFFCOAT™ PLATING
TUFFCOAT™ PLATING
One of the most common causes of hydraulic leaks is a cracked coupling nut or seat due to over-torquing. Gates has engineered a solution – Full-Torque Nut technology which is standard on all MegaCrimp® and GlobalSpiral™ couplings. Full-Torque Nut couplings are stronger and more durable than traditional staked-nut fittings. A large holding shoulder evenly distributes stress forces at the nut for higher resistance against cracking, even when inadvertently over-torqued. Increase equipment uptime by eliminating damaged couplings and leaks from too much torque. Over-Torque Protection Robust swivel joint allows for maximum torque Up to 24,000 psi burst pressure (-16 size G6K) Staked-nut provides less burst pressure protection Swivel joint sensitive to over-torquing 700 Percent Better than the 72-Hour SAE Standard
GlobalSpiral™ Couplings G20
>“Bite-the-wire” crimp for improved coupling retention
> Over 30 thread configurations
> Industry-leading tested-2x SAE Standard impulse cycles at +250°F (+121°C)
GlobalSpiral Couplings
No-Skive Convenience, Reduced Inventory GlobalSpiral couplings are specially engineered to provide superior performance for extreme high-pressure, highimpulse spiral-wire hydraulic hose applications. They can be used with all Gates MegaSys four- and six-spiral wire hose up to 8,000 psi. The innovative, two-piece, no-skive design reduces assembly time, labor, fabrication errors and contamination of the fluid power system. The work area stays clean, and the odors and dust normally created by skiving are eliminated. In addition, the two-piece design reduces parts inventory by 30 percent because only one stem is required for all spiral-wire hose types
White patches on couplings are salt residue, not corrosion
TuffCoat plating sets the global standard in both corrosion resistance and environmental friendliness.
Gates has removed all hexavalent chromium from its plating process. This metal, common in industrial plating, is toxic to the environment. Gates engineered TuffCoat plating to be stronger and more resistant to corrosion, without the toxicity of hexavalent chromium. TuffCoat plating is standard on MegaCrimp® and GlobalSpiral™ couplings. Tested under SAE J516 and ASTMB-117 salt-spray conditions, TuffCoat plating provided more than 500 hours of protection from red rust formation – almost 700 percent better than the 72-hour SAE standard. The Gates coupling with TuffCoat plating shows no red rust formation.
