China Hydraulic Hose Crimping Machine: MS-51 Series — Heavy-duty crimping workhorse for professional workshops.
Why Your Workshop Needs a Better Hose Crimping Solution
If you run a hydraulic repair shop, a fleet maintenance center, or an agricultural equipment service operation, you know this truth: a bad crimp costs more than the machine itself.
A single leaky hose assembly can cause downtime, equipment damage, safety hazards, and lost customer trust. Cheap crimpers deliver inconsistent results—too loose and you get leaks; too tight and you damage the fitting. The result? Rework, warranty claims, and a reputation you can't afford. The MS-51 Series hydraulic hose crimping machine from Mension Machinery solves this problem with industrial-grade precision (0.05mm), a powerful crimping force capable of withstanding 500 tons of crimping pressure, and reliable quality designed for daily, heavy-duty use.
The MS-51 Series is a line of benchtop hydraulic hose crimping machines engineered for professional hose assembly fabrication. Built on a proven platform, it delivers consistent, repeatable crimps for hydraulic hoses ranging from 1/4" to 2" (4SH).
The MS-51 Series is a benchtop hydraulic hose crimping machine designed for professional hose assembly fabrication. Based on a proven platform design, this series provides consistent and repeatable crimping results for hydraulic hoses ranging from 1/4 inch to 2" inches. With its one-piece forged-steel cylinder, precision micrometer adjustment, and dual operation modes, the MS-51 is the machine trusted by workshops across 60+ countries — from construction fleets in Africa to agricultural cooperatives in South America.
"We've had our MS-51 for over 3 years and it still cranks out perfect assemblies every single day. The precision dial is a game-changer."

7 Key Features That Make the MS-51 Stand Out
1. 500 Tons of Crimping Force — Handles 2" 4SH Hoses with Ease
The MS-51 delivers a massive 500 tons (500T) of crimping force—enough to handle the thickest, highest-pressure hydraulic hoses on the market. Whether you're crimping a thin 1/4" brake line or a heavy-duty 2" 4-spiral hose, the MS-51 has the power to get the job done right.
System pressure: 31.5 MPa
Hose size range: 1/4" – 2" (6–51 mm)
Crimping range: 14 – 87 mm
2. Precision Down to 0.05mm — No Guesswork, No Waste
Consistency is everything in hose fabrication. The MS-51 features a precision micrometer adjustment system that lets you dial in your crimp diameter with 0.01mm accuracy.
✅ ✅ Every crimp meets SAE/DIN specifications.
✅ No over-crimped or under-crimped assemblies.
✅ Reduced scrap rates—save money on fittings and hoses.
✅ Faster setup between hose sizes.
3. One-Piece Forged Steel Cylinder—Built to Last
Unlike machines with welded or bolted cylinder assemblies, the MS-51 features a one-piece forged-steel crimping head that has undergone high-hardness heat treatment. This design eliminates the risk of cylinder separation under load and ensures years of trouble-free operation, engineered for over 10,000 hours of continuous service.
4. Dual Operation Modes—Automatic for Speed, Manual for Control
Automatic Mode: Set your crimp diameter, step on the foot pedal, and the machine automatically completes the full crimp cycle. Perfect for high-volume production.
Manual/Inching Mode: Fine-tune your crimp with precise control. Ideal for complex fittings, prototyping, or training new operators.
(Switch between modes with a single toggle—no tools required) required.)
(Switch between modes with a single toggle—no tools required.)
5. Quick-Change Die System — 10 Die Sets Included
The MS-51's quick-change die system allows you to switch between hose sizes in under 30 seconds. No fumbling with screws, no complex adjustments.
Standard equipment: 10 sets of precision-machined dies covering the full 1/4" – 2" range, compatible with all major fitting brands (Parker, Eaton, Gates, etc.).
6. Foot Pedal Operation — Hands-Free Efficiency
The integrated foot pedal control allows you to keep both hands on the hose and fitting during crimping, improving safety, speed, and accuracy when handling heavy assemblies.
7. CE Certified — Meets European Safety Standards
The MS-51 Series is CE certified, featuring an emergency stop button, a safety guard on the crimping head, an IP54-rated electrical control panel, and a pressure relief valve system. Ready for regulated markets worldwide.
