Flexible Compact Spiral hose has longer service lifeParker Hannifin is launching an innovative flexible Compact Spiral hose that provides a notably long service life, meeting twice the required number of test cycles. It is suitable for use in both stationary and mobile industrial machinery in a wide range of applications, including construction, defence, oil and gas. Offering 5000 and 6000psi performance in a compact design, the new Compact Spiral delivers productivity improvements for OEMs and end users alike, with greater routing, installation, durability, size and weight advantages over conventional SAE spiral hoses.

Claimed to represent the biggest breakthrough in hose technology since Parker's No-Skive concept, the Compact Spiral hose offers many sophisticated new features without any compromise on hose life. Indeed, the new hoses can achieve two million impulse cycles – which is two times the ISO 18752-DC standard and four times the SAE requirement. This translates to a significantly longer service life in nearly all applications, particularly in those where many repeat cycles occur within a short timeframe - such as in injection moulding machines.

Compact Spiral hoses also offer a number of other important benefits, including greater flexibility, a smaller outside diameter and a tighter bend radius thanks to a high-performance inner tube that makes it possible to refine, redesign and significantly reduce overall hose construction. For example, the hose has half the bend radius and a 30 per cent smaller diameter than conventional SAE spiral hoses. It also requires one-third less effort to bend, meaning that bends can begin sooner and the total amount of hose needed is reduced by 20–55 per cent, depending on the application.

According to Parker, Compact Spiral hoses are also easier to route and install, saving valuable time and effort, and more hose can be routed into tight spaces where less flexible, larger diameter hoses simply would not fit. Customers can also jump up to a larger hose size to achieve better flow characteristics for their hydraulic systems while maintaining an outside diameter similar to the smaller hose that was previously installed; for instance, the outside diameter of a -12 size Compact Spiral equates to the diameter of a -10 size comparable SAE hose.

Furthermore, the new hose weighs up to 26 per cent less than standard spiral hoses. Combined with the increased ease of handling, this weight reduction leads to significant fuel savings for equipment with many hydraulic hoses, such as car carriers and refuse trucks. Additionally, shipping and packaging costs are also reduced.

The new 787TC (5000psi) and 797TC (6000psi) Compact Spiral hoses are available in sizes -8, -10, -12 and -16 and are backed by Parker's global network of manufacturing, sales and customer support centres.
