Technical Detail

Parker’s 71 Series fittings are designed as permanent, one-piece "bite-the-wire" crimp fittings. They offer fast, reliable assembly and support a wide range of hydraulic applications.
71 series
One-Piece Design

Integrated fitting and ferrule construction reduces part count, simplifies assembly, and lowers inventory requirements.

No-Skive Technology

Works with No-Skive hoses, eliminating the need to remove the hose cover before crimping — saving time and avoiding assembly errors.

Bite-the-Wire Connection

Special crimp profile “bites” into the hose reinforcement for a secure, permanent, leak-free connection under pressure.

Wide Size Range

Available from 3/8" up to 2" hose sizes, covering both standard and large-bore hydraulic applications.

High Compatibility

The 71 series hydraulic crimp fittings are designed for high-pressure applications and are compatible with 4-spiral hoses, and certain 6-spiral hoses depending on size and specification.

Applications

The 71 Series hydraulic crimp fittings are suitable for a wide range of high-pressure hydraulic systems, including:
Agriculture Equipment hydraulic Cylinder

Agricultural Machinery

In modern agriculture, equipment such as tractors, harvesters, and sprayers relies heavily on hydraulic power for lifting, steering, and precision control. The 71 Series Crimp Fittings, when paired with durable 4-wire hoses, provide reliable fluid transfer that can withstand constant vibration, exposure to dust, and varying weather conditions. This ensures long service life and reduced downtime in field operations, where efficiency and reliability are essential.
Construction Hydraulic hose Topa

Construction Equipment

Construction sites demand hydraulic systems that can endure extreme pressure, shock loads, and continuous operation. Machines like excavators, loaders, bulldozers, and cranes require fittings capable of handling rugged environments while ensuring safe, leak-free connections. The 71 Series fittings, matched with both 4-spiral hoses, deliver the strength and flexibility needed for heavy lifting, digging, and material handling, allowing contractors to keep projects on schedule with minimal hydraulic failures.

Mining & Quarrying

Mining and quarrying operations involve some of the toughest working conditions in the world, with equipment exposed to abrasive dust, high pressures, and heavy mechanical stress. Hydraulic systems power critical machinery such as haul trucks, rock drills, and crushers, all of which require maximum durability. The 71 Series Crimp Fittings, paired with 4-spiral hose assemblies, provide the extra reinforcement necessary to maintain system integrity under relentless pressure.
