Mobile hydraulic hose and connector specialist ENZED has introduced an extremely compact high-pressure spiral hose. Manufactured to strict ISO 18752-DC specifications, Parker’s Compact Spiral Hose in 5000psi and 6000psi specifications is a world first. It offers significant advantages in ease of installation, product size and weight, inventory savings and much more. Boasting half the bend radius of its SAE spiral hose equivalent, Compact Spiral can reduce the total amount of hose required from 20 to 55 percent. The spiral hose also features an outside diameter (OD) that is nearly 30 percent smaller than conventional spiral hose, resulting in one-third less physical effort in bending and routing. Its smaller OD also enables more hose to be fitted into tight quarters and allows for an increase in internal hose size if required for better flow characteristics.
Compact Spiral is tested to 2,000,000 impulse cycles – two times the ISO 18752-DC impulse cycle standard and four times the SAE impulse requirement, greatly extending service times between replacements. Parker’s highly abrasion-resistant ‘Tough Cover’ will outlast all non-abrasion resistant covers and is designed to deliver long, dependable service life in rigorous and/or remote installations. Compact Spiral simplifies the hose selection process – 787TC covers all 5000psi applications and 797TC meets all 6000psi hose requirements. Having one hose with two clearly defined pressure ratings eliminates any confusion. Hose connection fitting selection is also streamlined, as Parker’s 77 Series of hose ends covers all sizes of 787TC and 797TC hoses. The crimping operation is also simplified and the chance of mismatched hoses and fittings is eliminated. The hose features Parker’s Interlock No-Skive design, with both internal and external ‘Bite the Wire’ technology for assured connection strength and sealing. The inner tube compound also provides enhanced fluid compatibility (e.g. environmental fluids, Polyol Esters) reducing the need for specialty hoses to suit non-standard fluids.
“The Compact Spiral Hose is the most significant advancement in hydraulic hose since the introduction of Parker’s No-Skive connection technology more than 25 years ago,” said Parker Hannifin Group Product Manager, Domenic Gerace. “It delivers substantial performance and value for systems with high-pressure, high-impulse applications. These can include injection moulding, oil and gas, and large mobile equipment including off-highway, construction, forestry and mining. Customer surveys in these markets indicate that pressure rating, routing ease, abrasion resistance, bend radius and weight are top priorities in hose selection for these applications. Compact Spiral Hose sets new industry standards in all of those criteria, so ENZED customers can be confident that they are getting the most innovative and highest quality hydraulic hose system available today.”
