In the world of hydraulic hose assembly, precision is paramount—especially when working with small-diameter hoses where even minor crimping deviations can compromise connection integrity. The MT-P20 benchtop crimping machine, engineered by Qingdao Britop International Trading Co., Ltd., delivers exactly this level of precision for hoses ranging from 6mm to 20mm in diameter with 80 tons of consistent crimping force.
## Design Philosophy of the MT-P20
The MT-P20 represents a focused engineering approach: rather than attempting to cover the broadest possible hose range, it specializes in the small-diameter segment where precision requirements are most demanding. This specialization yields several advantages over general-purpose crimping machines.
At its core, the MT-P20 uses a compact benchtop form factor that occupies minimal workshop space while delivering professional-grade crimping performance. The machine’s frame is constructed from high-strength alloy steel, precision-machined to maintain die alignment within micron-level tolerances throughout thousands of crimping cycles. This structural rigidity is essential for small-diameter hoses, where die misalignment of even a fraction of a millimeter can produce oval deformation and inconsistent crimp diameters.
## Technical Specifications

| Crimping Range | 6mm – 20mm |
| Maximum Crimping Force | 80 tons |
| Machine Type | Benchtop, Hydraulic |
| Die Configuration | 8-segment precision dies |

The 80-ton crimping force of the MT-P20 is carefully calibrated for the 6-20mm hose range. This force level provides sufficient compression energy to properly deform standard hydraulic fittings in this size category without the risk of over-crimping that can occur when using larger machines at their lower force settings. The relationship between force and precision is particularly important: machines designed for much higher forces often sacrifice fine control at the lower end of their range, whereas the MT-P20 operates entirely within its optimal performance envelope.
## Applications and Use Cases
### Hydraulic Repair Workshops
Independent hydraulic repair shops handling agricultural, construction, and industrial equipment frequently encounter small-diameter hoses in pilot circuits, lubrication systems, and auxiliary hydraulic functions. The MT-P20 provides these shops with a dedicated small-hose crimping solution that complements larger machines like the MT-51BY series. Having a specialized small-diameter crimper reduces die changeover time and eliminates the quality compromises of crimping small hoses on oversized equipment.
### Automotive and Motorsport
High-performance automotive hydraulic systems—including brake lines, clutch circuits, and power steering assemblies—demand exceptional crimp precision. The MT-P20’s 8-segment die configuration delivers the uniform radial compression required for thin-walled automotive fittings, where concentricity is critical for sealing performance. Motorsport teams particularly value the MT-P20’s compact size for trackside hose fabrication.
### Laboratory and Test Equipment
Research laboratories and test facilities that build custom hydraulic circuits for experimental apparatus frequently work with small-diameter hoses and specialized fittings. The MT-P20’s precise force control and consistent crimp quality make it suitable for applications where assembly repeatability is essential for experimental validity.
### Mobile Field Service
The MT-P20’s manual operation and modest weight make it transportable in a service vehicle, providing field technicians with on-site small-hose fabrication capability. When paired with portable cutting and skiving tools, technicians can fabricate complete small-diameter hose assemblies without returning to a central workshop.
## Crimping Precision: The 8-Segment Die Advantage
The MT-P20 employs an 8-segment die configuration, which offers superior crimp roundness compared to 6-segment dies commonly found on entry-level machines. Each additional die segment reduces the angular gap between compression points, resulting in more uniform radial force distribution around the fitting circumference.
For small-diameter hoses, this uniformity is critical. A 6mm hose with 6-segment dies has approximately 3.14mm of arc length between die contact points; with 8-segment dies, this gap reduces to approximately 2.36mm. The tighter die spacing minimizes the risk of forming polygonal deformation patterns on the crimped ferrule, ensuring consistent grip force around the entire circumference.
## Integration with the Complete Assembly Workflow
The MT-P20 functions as part of a complete hose assembly system. For optimal results, it should be paired with appropriate cutting and skiving equipment:
Hose Cutting: Clean, square cuts are essential before crimping. The QD-51 dust-free electric hydraulic hose cutting machine provides burr-free cutting for hoses within the MT-P20’s diameter range.
Hose Skiving: For hoses requiring skiving, the MT-51BJ-2 dust-free high-pressure skiving machine removes the outer cover with precision, ensuring proper metal-to-metal contact during crimping.
Quality Verification: Digital or mechanical crimp diameter gauges should be used to verify every assembly before it enters service.
## Maintenance Requirements
The MT-P20’s relatively simple hydraulic system requires minimal maintenance:
Daily: Wipe die surfaces clean, inspect for wear patterns, check hydraulic oil level
Weekly: Lubricate pivot points, inspect hydraulic hoses for leaks or damage
Monthly: Verify pressure gauge accuracy, check die alignment, inspect frame bolts for proper torque
Annually: Replace hydraulic oil, perform complete calibration check
## Comparison with Larger Crimping Machines
| Feature | MT-P20 | MT-51BY | CBK-220 |
|———|——–|———|———|
| Crimping Range | 6-20mm | 6-51mm | 6-102mm |
| Crimping Force | 80T | 300T | Industrial |
| Die Segments | 8 | 8/12 | Variable |
| Operation | Manual | Electric-Hydraulic | Hydraulic |
| Best For | Small hoses, precision work | General industrial | Large-diameter, heavy-duty |
The MT-P20 is not a replacement for larger machines but a complementary tool that excels in its specialized range. Workshops that handle diverse hose sizes benefit most from having both a small-diameter specialist like the MT-P20 and a general-purpose machine like the MT-51BY.
The MT-P20 benchtop crimping machine represents a purpose-built solution for the precision demands of small-diameter hydraulic hose assembly. Its focused design philosophy, 8-segment die configuration, and 80-ton force specification combine to deliver consistent, reliable crimps in the 6-20mm range.
