Compact Spiral hose offers multiple advantages over conventional hose

New Compact Spiral hose from Parker Hannifin Corporation offers 5,000- and 6,000-psi hose performance in a compact design to deliver greater routing, installation, size, weight, and service life advantages compared with conventional SAE spiral hose.

New 787TC (5,000-psi) and 797TC (6,000-psi) Compact Spiral hose is available in sizes -8, -10, -12, and -16. Both hose lines will be extended at a future date to include larger sizes.

Features of this patent-pending hose include:

  • Greater flexibility, smaller outer diameter (OD), tighter bend radius — For Compact Spiral, Parker engineered a new high-performance inner tube that made it possible to refine, redesign, and reduce overall hose construction. Compact Spiral has half the bend radius and a nearly 30% smaller OD than conventional SAE spiral hose. It also requires a third less effort to bend.

    As a result, bends can begin sooner. This reduces the total amount of hose needed by 20%-55% depending on the application. Compact Spiral is also easier to route and install. More hose can also be routed into tight quarters where larger-diameter, less-flexible hoses would not fit. Furthermore,users can “jump up” to a larger hose size to achieve better flow characteristics for their hydraulic system while maintaining an OD similar to the smaller hose previously installed.

  • Longer performance life — Compact Spiral hose has been successfully tested to 2,000,000 impulse cycles, which is two times the ISO 18752-DC standard and four times the SAE requirement. This equates to longer service life in nearly all applications, particularly those where many repeat cycles occur within a short timeframe.

  • Less weight — Compact Spiral weighs up to 26% less than standard spiral hose. This weight reduction can lead to fuel savings for equipment with many hydraulic hoses. Shipping and packaging costs are also reduced.
