Gates MegaSpiral hydraulic hose and GSM coupling

The Gates MegaSpiral hydraulic hose is tested to 1,000,000 impulse cycles, two times the SAE requirement, and is conducted at tighter bend radii - up to one-third the minimum SAE bend radius. The greater flexibility and improved bend radii is claimed to save up to 47% on hose assembly costs.

The 2″ diameter 6000 psi constant pressure hose (32EFG6K) is designed with high-tensile steel and nitrile tube for use with biodegradable hydraulic fluids and vegetable oils as well as standard petroleum-based fluids. The hose is available with the MegaTuff abrasion-resistant cover, which may increase service life as well as lowering maintenance and replacement costs by protecting the hose from cuts, friction caused by other moving parts and from mechanical impacts.

To match with the 32EFG6K hose, Gates has released the Gates Spiral Maximum (GSM) coupling; for use on 32EFG6K and other Gates high-pressure 6-spiral wire hoses with inside diameters of 1.5” or more. The GSM coupling is one piece, meaning no separate ferrule and less inventory, and delivers 1,000,000 impulse cycles performance with no-skive convenience.

A 2″ diameter 6000 psi working pressure six-spiral wire hose previously required hydraulic system designers to use skived assemblies. The process for removing the hose end cover or tube material in order to attach the coupling introduces a risk of contamination from dust and debris and the risk of improper assembly.

In high-pressure, high-impulse applications, assembly error can result in leaking at the hose/coupling interface, or worse, the coupling blowing off, posing a serious hazard and safety risk. The no-skive, one-piece coupling makes for easier and safer hose assemblies.
