Detailed Explanation of DMK12-23-C2 Multi-Pipe Butt Joint Product
2025-07-101. Product Overview
DMK12-23-C2 is an industrial-grade multi-pipeline quick butt joint, adopting a modular combined design. It can connect 12 pipelines simultaneously (with a pipe diameter range of 4-12mm) to realize centralized distribution or confluence of multi-channel fluids (gas/liquid). It is specially designed for the compact pipeline layout of automation equipment, hydraulic/pneumatic systems.
2. Core Features
✅ High-density integration
- A single joint integrates 12 independent channels (C2 may represent a 2-row × 6-column layout)
- Saves 90% of installation space (compared with traditional single-pipe joints)
✅ Quick disassembly and assembly
- Push-pull locking mechanism (with anti-loosening buckle)
- Supports blind insertion operation (O-ring pre-sealing)
✅ Multi-material adaptation
- Main body: anodized aluminum alloy (corrosion-resistant)
- Sealing: NBR/FKM (oil-resistant/high-temperature resistant)
- Applicable pipes: PU/Nylon/metal hoses
✅ Safety protection
- Each channel is independently sealed (zero cross-flow risk)
- Pressure test: 1.5 times the working pressure (0.8MPa for standard type)
3. Model Interpretation
| Code Segment | Meaning |
|---|---|
| DMK | Series name (multi-pipe modular joint) |
| 12 | Maximum support for 12-pipe butt joint |
| 23 | Interface specification (such as G1/8″ or M5 thread) |
| C2 | Configuration version (may include sealing material/color code) |
4. Technical Parameters
| Item | Parameter |
|---|---|
| Number of channels | 12 |
| Applicable pipe diameter | 4-12mm (inner diameter/outer diameter needs to be confirmed) |
| Working pressure | 0.2-0.8MPa (liquid) / 1.0MPa (gas) |
| Temperature range | -20℃~+80℃ (FKM seal can reach +120℃) |
| Seal leakage rate | ＜0.1mL/min@0.5MPa |
| Weight | Approximately 350g (aluminum alloy type) |
5. Typical Applications
- Centralized air supply for multi-cylinders: synchronous control of 12 stations in automated production lines
- Medical equipment: multi-pipeline connection of dialysis machines/ventilators
- Testing systems: multi-channel monitoring of fluid pressure/flow
6. Installation Guide
Step 1: Pipeline preprocessing
- Cut the pipe orifice to be flush (it is recommended to use a special pipe cutter)
- Remove burrs (to avoid scratching the sealing ring)
Step 2: Joint assembly
- Note:
- Insertion depth must be ≥1.5 times the pipe diameter
- Pressure test is required for the first use
7. Selection Comparison
| Model | Number of channels | Pressure resistance | Features |
|---|---|---|---|
| DMK8-20-C1 | 8 | 0.6MPa | Economical type |
| DMK12-23-C2 | 12 | 0.8MPa | Standard type |
| DMK16-25-C3 | 16 | 1.2MPa | High-pressure version |
8. Maintenance and Troubleshooting
| Problem | Solution |
|---|---|
| Single-channel leakage | Replace the corresponding O-ring (specification 3×1.5mm) |
| Large insertion and extraction resistance | Apply silicone-based grease |
| Cross-flow phenomenon | Check whether impurities are embedded in the sealing surface |
9. Technical Advantages
Compared with traditional schemes:
- Installation time is reduced by 70% (no need to tighten joints one by one)
- Maintenance cost is reduced (modular replacement of faulty units)
Comparison with competing products:
- 20% higher channel density than similar products
- Supports 360° rotation positioning (to avoid pipeline distortion)
10. Summary
DMK12-23-C2, with its high-density integration and quick connection design, perfectly solves the three major pain points of multi-pipeline systems:
- Large space occupation → compact layout
- Low installation efficiency → push-pull blind insertion
- Difficult maintenance → modular replacement
Recommended scenarios:
- Mobile equipment that needs frequent disassembly (such as end tools of robotic arms)
- Clean room environment (design without particle shedding)
- Hydraulic systems with multi-branch synchronous control
