Products Details

The 78 Series One-Piece Hydraulic Crimp Fittings are designed for the most demanding hydraulic applications, offering a permanent, high-pressure connection in a compact, leak-resistant design. By integrating the hose stem and ferrule into a single component, the 78 Series eliminates multiple assembly steps, reduces potential leak points, and delivers a stronger, more reliable connection.
One-Piece Integrated Design

Combines the stem and ferrule into one precision-machined component, eliminating the need for separate collars or sleeves. This reduces assembly time, simplifies inventory management, and ensures a more consistent crimp profile.

High-Pressure Capability

Engineered for four- and six-spiral wire hydraulic hoses, the 78 Series can handle extreme working pressures, making it suitable for construction, mining, oil & gas, forestry, and other heavy-duty sectors.

No-Skive Compatibility

Works with No-Skive hoses, meaning no removal of the outer hose cover is needed before crimping. This not only saves time but also reduces the risk of hose damage during preparation.

78 Series
Optimized Flow Path

Internal geometry is designed to minimize turbulence and maintain consistent fluid velocity, reducing heat generation and ensuring efficient system performance.

Material Options

Available in high-strength carbon steel for standard hydraulic applications or stainless steel for corrosive, marine, or chemical processing environments.

Consistent, Repeatable Assembly

Designed to work seamlessly with ’s standard crimping equipment, ensuring every fitting is crimped to exact tolerances for long-term leak-free performance.

Applications

The 78 Series One-Piece Fittings are engineered to perform in the most demanding environments, delivering secure, leak-free connections where system uptime and safety are critical.
Hoses in Construction

Construction Machinery

Ideal for high-pressure hydraulic systems in excavators, cranes, bulldozers, and concrete pumps. These fittings withstand constant vibration, heavy loads, and varying environmental conditions on job sites.
Underground Mining Hydraulic Systems

Mining Equipment

Built to handle the extreme demands of mining operations, including haul trucks, loaders, and drilling rigs. The 78 Series resists abrasion from dust and debris, endures high-vibration conditions, and maintains seal integrity under continuous heavy loads.
Hydraulic Quick coupler factory Industrial

Industrial Sector

Suitable for hydraulic systems in manufacturing plants, steel mills, and processing facilities. From hydraulic presses to injection molding machines, these fittings help maintain stable operating pressures, improve system efficiency, and enable quick hose replacements with minimal disruption to production lines.

Advantages of 78 Series Hydraulic Fittings

Faster Assembly in High-Volume Production

The integrated one-piece design reduces handling time, making it ideal for assembly lines and large-scale OEM operations where speed directly impacts productivity.

Consistent Crimp Quality

With no separate ferrule to align, crimp results are uniform across batches, reducing the risk of rework and ensuring repeatable performance in every connection.

Lower Risk of Contamination

Fewer handling steps mean fewer opportunities for dirt, dust, or debris to enter the hose assembly during manufacturing or maintenance.

Improved Structural Integrity

By eliminating the split between the ferrule and fitting body, the 78 Series offers superior mechanical strength in high-vibration and high-impact environments.

Reduced System Weight

The compact, integrated construction can be lighter than comparable multi-piece fittings, contributing to overall system weight savings — especially beneficial in mobile equipment.

Inventory Simplification

Only one part number to manage per configuration, cutting down on SKU complexity and streamlining procurement processes for distributors and maintenance teams.

FAQ

What is the main difference between the 78 Series and other hydraulic fittings?
The 78 Series is a one-piece design where the stem and ferrule are integrated. This simplifies assembly, improves consistency, reduces leak points, and is ideal for high-pressure spiral hose applications
Can the 78 Series be used with any hydraulic hose?
The 78 Series is specifically designed for use with -approved No-Skive spiral hoses. Using non-compatible hoses may lead to performance issues or void warranty coverage.
What pressure ratings can the 78 Series handle?
Depending on size and hose combination, the 78 Series can handle working pressures up to 6,000 psi.
Do I need to skive the hose before assembly?
No. The 78 Series is fully compatible with No-Skive hoses, eliminating the need to remove the outer cover prior to crimping.
What materials are available?
Standard fittings are manufactured in high-strength carbon steel. Stainless steel versions are available for applications involving corrosive fluids, marine environments, or chemical exposure.
Are there different configurations available?
Yes. The 78 Series is offered in multiple configurations including straight, 45°, and 90° elbows, with thread options such as JIC, NPTF, SAE Code 61/62 flanges, DIN Metric, and ORFS.
