New Compact Spiral hose from Parker Hannifin is claimed to offer unprecedented 5000 and 6000psi hose performance in a compact design to deliver measurably greater routing, installation, size, weight and service life advantages compared with conventional SAE spiral hose. Together, these benefits create considerable material, shipping and inventory cost savings for customers.
Compact Spiral hose represents the most significant advancement in Parker hydraulic hose technology since the introduction of No-Skive fittings more than 25 years ago. New 787TC (5000psi) and 797TC (6000psi) 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.
The many innovative and proprietary features of the patent-pending Compact Spiral hose are said to establish new standards in customer value, as outlined below.
Greater flexibility, smaller diameter and tighter bend radius
For the Compact Spiral ose, Parker engineered a new high-performance inner tube that made it possible to refine, redesign and significantly reduce the overall hose construction. Compact Spiral has half the bend radius and an outside diameter that is nearly 30 per cent smaller than those of conventional SAE spiral hoses. It also requires one-third less effort to bend.
As a result, bends can begin sooner, which reduces the total amount of hose needed by 20-55 per cent, 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 spaces where larger-diameter, less flexible hoses simply would not fit. Furthermore, customers can use a larger hose size to achieve better flow characteristics for their hydraulic system while maintaining an outside diameter similar to the smaller hose that was previously installed.
Compact Spiral hose has been successfully tested to 2million 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.
Compact Spiral hose weighs up to 26 per cent less than standard spiral hose. In addition to easing 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.
