Higher pressures. Rugged environments. Constant
movement. These are the conditions today's
hydraulic hoses have to stand up to every day –
day after day. Part of our new, improved MegaSys ®
line, G8K spiral-wire hose is designed and
engineered to handle extreme applications and
outperform any other 8,000 psi (55.2 MPa) hose
on the market today.
With flexibility comparable to SAE 100R15
specifications, G8K hose is ideal for extreme
high-pressure, high-impulse applications found
in mobile construction equipment, boom arms,
hydrostatic drives, mining trucks, excavators and
G8K services applications that use standard
petroleum-based hydraulic fluids. Both sizes are
compatible with new two-piece, no-skive G8K
couplings for outstanding, leak-free performance
and easy assembly fabrication. G8K couplings
are available only with FLC terminations to meet
8,000 psi performance.
To handle your toughest high-pressure, highimpulse,high-movement
G8K MegaSpiral hose – it's tough to beat.
