Hydraulic Systems


Your hydraulic system wouldn't be complete without couplings. If you don't find exactly what you need here, Gates can design and manufacture custom couplings for your application.

  • MegaCrimp®: The versatile, weep-free coupling for wire-braid hose has a patented "C" insert that stays round like the hose, so there's no polygon effect. Plus, one size accommodates many different hose ODs, simplifying your inventory.

  • GlobalSpiral®: Used for all Gates high-pressure spiral wire hoses with ratings from 3,000 to 6,000 psi, its no-skive permanent coupling design reduces labor, assembly time, errors and contamination from rubber dust.

  • Full-Torque Nut™: Available on MegaCrimp® and GlobalSpiral® couplings, it shows unsurpassed resistance to over-torquing and cracking for increased productivity and uptime.

  • Quick-Lok™: Cut costs with these threadless couplings designed for compact, power-intensive machines. They go together fast and stay together with no leaks. For more information download the Quick-Lok Design Guide.

  • TuffCoat® Xtreme™: This plating protects couplings from corrosive conditions commonly found in coastal areas and offshore drilling platforms and offers 840 hours of red rust corrosion resistance.

Be sure to download the Full-Torque Nut Brochure to crack down on nut cracking, seat damage, leaks, corrosion and premature coupling failure.
