April 5, 2010 - Compact Spiral hose from Parker Hannifin offers 5,000- and 6,000-psi hose performance in a compact design to deliver measurably greater routing, installation, size, weight and service life advantages compared with conventional SAE spiral hose. Combined, these benefits create considerable material, shipping and inventory cost savings for customers. 787TC (5,000 psi) and 797TC (6,000 psi) Compact Spiral hose is immediately available in sizes -8, -10, -12 and -16. Both hose lines will be extended at a future date to include larger sizes. The many innovative and proprietary features of patent-pending Compact Spiral hose establish new standards in customer value.
Greater Flexibility, Smaller O.D. Size, Tighter Bend RadiusFor Compact Spiral, Parker engineered a new high-performance inner tube that made it possible to refine, redesign and significantly reduce overall hose construction.
Compact Spiral has 1/2 the bend radius and a nearly 30% smaller O.D. than conventional SAE spiral hose. It also requires 1/3 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, which saves time and reduces effort. More hose can also be routed into tight quarters where larger diameter, less flexible hoses simply would not fit.
Furthermore, customers can "jump up" to a larger hose size to achieve better flow characteristics for their hydraulic system while maintaining an O.D. similar to the smaller hose that was previously installed (for instance, the O.D. of a -12 size Compact Spiral hose equates to the O.D. of a -10 size comparable SAE hose).
Longer Performance LifeCompact 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 significantly longer service life in nearly all applications - particularly those where many repeat cycles occur within a short timeframe, such as with an injection molding machine. Less WeightCompact Spiral weighs up to 26% less than standard spiral hose. In addition to ease of handling, this weight reduction can lead to significant fuel savings for equipment with many hydraulic hoses, such as car carriers and refuse trucks. Shipping and packaging costs are also reduced.
