797TC
Compared with conventional spiral hose, Parker’s Compact SpiralTM 797TC Hose
offers measurably greater advantages in routing and installation, product size
and weight, inventory savings and much more. A world’s frst, this development is
the most signifcant advancement in hydraulic hose since the introduction of Parker’s
No-SkiveTM technology more than 25 years ago.
• Half the bend radius of SAE spiral
• One-third less effort to bend
• Nearly 30% smaller O.D. by area than SAE spiral
• Twice the impulse/life – tested to 2,000,000 cycles
• Flex impulse tested
• Constant 6000 psi across all sizes
• Less hose weight than SAE spiral
