| Equipment requires compact hose layout | Reduces unnecessary routing complexity |
| Hydraulic assembly needs standardized metric connection | Matches DIN metric hydraulic systems |
| Buyer needs repeatable hose assembly production | Supports stable batch crimping and assembly |
| Hydraulic system needs leakage control | 24° cone O-ring structure improves sealing reliability |
| Heavy-duty hose requires stronger retention | Interlock structure improves hose grip after proper assembly |
| Advantage | Product Design | Buyer Value |
|---|---|---|
| Metric Female Connection | Designed for DIN metric hydraulic systems | Suitable for machinery using metric hydraulic ports |
| 24° Cone O-Ring Seal | Combines cone sealing with O-ring assistance | Helps improve sealing stability and reduce leakage risk |

| Interlock One Piece Structure | Integrated fitting body and hose tail design | Helps improve assembly consistency and sourcing efficiency |
| DIN / ISO Compatibility | ISO 8434-1 / DIN 3865 standard | Easier replacement, matching and international sourcing |
| Multiple Size Options | Covers common metric thread and hose bore sizes | Supports different hydraulic hose assembly requirements |
The Metric 24° Cone O-Ring connection is widely used in hydraulic systems that require stable sealing and metric thread compatibility. It is especially suitable for DIN hydraulic systems used in European-style machinery, industrial hydraulic equipment and heavy-duty mobile equipment.
| Structure | Function |
|---|---|
| Metric Female Thread | Connects with compatible metric male hydraulic fittings |
| 24° Cone Seat | Provides the main sealing interface |
| O-Ring | Supports additional sealing stability and leakage control |
| Straight Body | Allows direct hose-to-port connection |
| Interlock Hose Tail | Works with hydraulic hose and ferrule for strong hose retention |
This structure helps buyers reduce leakage problems caused by incorrect sealing surfaces, poor thread matching or unstable hose assembly.
This product is different from 45° and 90° hose fittings. It is best used when the hose does not need angle correction and can be routed directly from the hydraulic port.
| Suitable Situation | Why Choose This Product |
|---|---|
| Direct metric port connection is required | Straight structure connects hose and port directly |
| Hydraulic system uses DIN metric fittings | Metric female 24° cone O-ring design matches DIN systems |
| Hose routing space is sufficient | Straight fitting avoids unnecessary angle changes |
| Batch hose assembly production is required | One-piece interlock structure supports consistent assembly |
| High-pressure spiral hose is used | Interlock tail helps improve hose retention |
| Replacement of metric hydraulic fittings is needed | Standard thread options support maintenance sourcing |
| Hose Type | Typical Use | Suitability |
|---|---|---|
| R13 Hydraulic Hose | Very high-pressure hydraulic systems | Suitable |
| R15 Hydraulic Hose | Heavy-duty high-pressure systems | Suitable |
| 4SP Hydraulic Hose | Four-wire spiral hydraulic hose assemblies | Suitable |
| 4SH Hydraulic Hose | Heavy-duty four-wire spiral hose assemblies | Suitable |
| Skived Hydraulic Hose | Hose prepared for interlock crimping | Suitable |
| Spiral Hydraulic Hose | Construction, mining and industrial hydraulic systems | Suitable |
Correct matching between the hose, fitting, ferrule and crimping parameters is important for final hose assembly performance.
| Application Area | Typical Equipment | Why This Fitting Is Used |
|---|---|---|
| Construction Machinery | Excavators, loaders, bulldozers, cranes, concrete pumps | Provides stable metric hydraulic hose connections for heavy-duty operation |
| Mining Machinery | Mining trucks, drilling rigs, crushers, underground equipment | Supports high-pressure hose assemblies under vibration and shock load |
| Agricultural Machinery | Tractors, harvesters, sprayers, lifting systems | Suitable for metric hydraulic systems used in outdoor mobile equipment |
| Metallurgical Equipment | Rolling mills, hydraulic presses, clamping systems | Supports stable hydraulic power transmission in continuous operation |
| Petroleum Equipment | Oilfield machinery, drilling systems, pressure equipment | Provides reliable sealing for demanding hydraulic circuits |
| Wind Power Systems | Hydraulic pitch systems, service equipment, maintenance systems | Suitable for metric hydraulic hose assemblies requiring stable sealing |
| Industrial Hydraulic Systems | Hydraulic power units, machine tools, injection molding machines | Supports direct hose routing and standardized metric connections |
| Fitting Type | Best Used For | Buyer Selection Logic |
|---|---|---|
| Straight Metric 24° Cone O-Ring Interlock Hose Fitting | Direct hose connection with aligned port direction | Choose when the hose can run straight from the metric port |
| 45° Metric Female Hydraulic Hose Fitting | Moderate angle correction and compact routing | Choose when the hose needs to avoid interference or reduce bending stress |
| 90° Metric Female Hose Fitting | Sharp direction change in limited space | Choose when the hose must turn immediately after the port |
If the hydraulic port direction and hose routing path are aligned, the straight 20513RW metric interlock fitting is usually the cleaner and more direct option.
| Option | Available Choice | Recommended Use |
