797

Compact Spiral

Hose

High pressure, low weight makes installation easy

Parker’s GlobalCore 797 hose provides 6,000 psi (42 MPa) constant working

pressure in all sizes. Compared with conventional spiral hose, 797 hose offers

measurably greater advantages in routing and installation, product size and

weight, inventory savings and much more. The 797 hose exceeds the ISO 18752

performance specification.

½

the bend radius of SAE spiral

• 6,000 psi constant working pressure in all sizes

• Exceeds ISO 18752 performance specification (BC/CC/DC)

• Nearly 30% smaller O.D. by area than SAE spiral

• Twice the impulse/life – tested to 2,000,000 cycles

• Flex impulse tested, providing a hose superior in both performance and service life

• 30% less hose weight than SAE spiral
