GL Couplings

Gates® Low pressure couplings with pre-crimped soft shell has been specifically designed to work with lower pressure hydraulic suction lines and low pressure return line hose. Its short body length provides the necessary grip for low pressure hose requirements, and the bubble pattern crimp design ensures the similar optimal sealing to that of helical wire hoses on return vacuum applications.

  • GL designed for Multi Master™ SD MegaFlex™.
  • GL designed for pressure with MegaTech.
  • GL designed for suction with GMV.

Features and Benefits

  • The GL coupling range kicks off where the GSP range stops: starting at an internal diameter of -40 (2-1/2") up to -64 (4").
  • Handles the low pressure performance needs of the hose, but with a smaller, light weight coupling.
  • Coated with TuffCoat plating - more than five times better corrosion resistance than SAE ASTMB117 specification.
