Manufactured to ISO 18752-DC specifications, Parker’s compact spiral hose in 5000psi and 6000psi specifications offered ease of installation, product size and weight, and inventory savings, the company said.
Compact Spiral also features an outside diameter that is nearly 30% 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.
Its compact size weighs 25% less than conventional spiral hose, offering potential savings in shipping and packaging costs and improved fuel consumption in mobile equipment.
Compact Spiral is tested to 2,000,000 impulse cycles – two times the ISO 18752-DC impulse cycle standard, greatly extending service times between replacements.
Parker’s abrasion-resistant “Tough Cover” will outlast all non-abrasion resistant covers and is designed to deliver long, dependable service life in rigorous and remote installations, the company claims.
Total hose inventory can also be reduced by more than 60% in applications where 5000psi and 6000psi requirements are presently covered by up to three conventional hose types.
Compact Spiral simplifies this process – 787TC covers all 5000psi applications and 797TC meets all 6000psi hose requirements.
Hose connection fitting selection is also streamlined, as Parker’s 77 Series of hose ends covers all sizes of Compact Spiral 787TC and 797TC hose.
This simplifies fitting selection when making assemblies and reduces hose fitting inventory by 50%, the company claims.
The crimping operation is also simplified and the chance of mismatched hoses and fittings is eliminated.
Compact Spiral hose features Parker’s exclusive interlock no-skive design, with both internal and external “bite the wire” technology for assured connection strength and sealing.
Parker’s inner tube compound also provides enhanced fluid compatibility to reduce the need for specialty hoses to suit non-standard fluids, according to the company.
“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,” Parker Hannifin Group product manager Domenic Gerace said.
“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.”
