The Gates GlobalSpiral™, High™ (GSH) and GlobalSpiral Plus™ (GSP) no-skive couplings are for heavy-duty hydraulic applications in mining, construction, drilling and other high-pressure, high-impulse industrial applications. These couplings are an extension of Gates GlobalSpiral coupling line. They have been reengineered to handle pressures up to 6,000 psi for -24 (1-1/2") and -32 (2") I.D. hose operating in the toughest working environments.

GSH and GSP couplings are available in over 30 thread configurations including SAE, DIN, BSP, Komatsu-style, JIS and CAT flange. Couplings are tested to 1,000,000 impulse cycles, double the SAE standard of 500,000 impulse cycles. TuffCoat™ plating provides more than four times better corrosion resistance than the SAE ASTMB117 specification.

No Skiving is required with GSH and GSP couplings. This saves time, labor, equipment and assembly errors. And the shop area stays clean and odor free. The result is premium quality assemblies and lower costs.

  • • A one-piece, no-skive connector. Replaces 24, 32 PCM.

  • • A two-piece design with 1 stem and 1 ferrules which
  •   replaces 24 and 32 PCS / PC.

IMPORTANT: Gates has stopped production of PC, PCS and PCM couplings but will continue to manufacture ferrules so we can use up old stock of couplings. Royal Brass and Hose is committed to helping you through this transition. Contact Customer Service if you have any questions: 1-800-669-9650.

WARNING: DO NOT use the crimp settings for the old couplings. GSH couplings are specifically engineered to crimp on Gates EnviroFluid 6-spiral hose. Do not "mix and match" old products (PCM couplings) with new products (EFG5K and EFG6K hose). GSP couplings are compatible with both EnviroFluid and Neoprene 4-spiral hose. Do not use old PCS couplings with new EnviroFluid hose.
