Key Features of 71 Series Hydraulic Crimp Fittings

The 71 Series hydraulic crimp fitting consists of two primary parts — the fitting body and the ferrule. The fitting body forms the connection interface with the hydraulic port, while the ferrule is crimped onto the hose to create a secure and permanent connection.

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.

Versatile Configurations

Offered in straight, 45°, 60°, 90°, and 110° elbows, flanges, and threaded options to suit different routing and system designs.

High Compatibility

The 71 Series hydraulic crimp fittings are designed for high-pressure applications and are compatible with 4-spiral hoses.

Applications

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

Construction Machinery

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.

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 , provide reliable fluid transfer that can withstand constant vibration, exposure to dust, and varying weather conditions.

FAQ

What type of hoses are compatible with 71 Series fittings?

The 71 Series is designed for high-pressure hydraulic hoses, including 4-spiral hoses.

Do I need to skive the hose before crimping?

No. The 71 Series is a no-skive fitting, which means you don’t need to strip or skive the hose cover before crimping. This makes assembly faster and reduces errors.

What sizes are available?

The fittings cover hose sizes from 3/8" (-6) up to 2" (-32), with a wide variety of end connections including straight, elbow, flange, ORFS, and JIC types.

What is the pressure rating of 71 Series fittings?

Pressure ratings vary by hose size and type, but the series supports applications up to 6000 psi when used with the correct spiral hoses.

What materials are they made of?

Standard versions are made from carbon steel with protective plating, while stainless steel options are available for corrosive or marine environments.

What industries use the 71 Series most often?

Common industries include agriculture, construction, mining, quarrying, industrial hydraulics, metallurgy, and oilfield/offshore equipment.
