Hydraulic Couplings

GLX Couplings: The Gates GLX™ coupling is specifically designed for textile-reinforced hoses with working pressures up to 1,000 psi. It is a one-piece staked ferrule design stocked in the popular male pipe NPTF 30° cone seat and female JIC 37° flare swivel terminations. Manufactured to provide the optimum coupling insertion force, one can feel the hose "hit bottom." Moreover, the coupling stays in place; it does not inadvertently fall off before crimping.

The GLX couplings are crimpable on all the standard Gates crimpers using the same dies as MegaCrimp (plus the 20 die set for 1/4"). The unique “bubble” at the coupling collar after crimping ensures maximum coupling pull-off resistance and reduced tube and cover bulges for a streamlined connection inside and out. The smooth ferrule ID does not damage textile reinforcements. These couplings are finished with the exclusive Gates TuffCoat™ plating on the stem and ferrule components to provide an estimated four times greater rust resistance than the standard plating- that means, more than 400-hour red rust corrosion protection in SAE-J516 and ASTMB-117 salt spray test conditions.

The GLX coupling line brings simplicity and efficiency to your assembly operations. One coupling per size fits all Gates Air and Multi-Purpose, LP350 and Cyclone hoses. There’s no need to decide which ferrule to use with which hose. This simplifies your assembly procedures while keeping inventories to a minimum. Following Gates crimp recommendations ensures assemblies with top quality, performance and safety.
