Products Description
This series of flexible metal hoses with quick connect fittings adopts integrally formed 304 and 316L stainless steel corrugated pipes. The outer high-density braided mesh enhances pressure resistance and fatigue resistance. Both ends are equipped with industrial-grade self-locking quick connectors, including two mainstream structures: single self-closing and double self-closing. The connector is built with precision valve cores and high and low temperature resistant fluororubber seals, which automatically cut off pressure and seal fluid during plugging and unplugging, avoiding medium dripping and gas leakage without manual pipe sealing. The pipe body is softened by annealing technology with flexible bending without dead angles, supporting multi-angle bypass installation in narrow spaces, no rigid deformation and no welding leakage hidden dangers. The overall structure is vibration-resistant, oil-resistant and weak acid and alkali corrosion resistant, adapting to alternating cold and hot medium transportation. It supports thousands of repeated plugging cycles with stable and non-degraded performance. All products pass air tightness, pulse pressure resistance and repeated plugging life tests before delivery, specially customized for non-fixed, high-frequency disassembly and temporary fluid transportation working conditions.
Product Advantages
Tool-free quick plug and self-locking, greatly improving operation and maintenance efficiency
It abandons the complicated installation process of traditional threads and flanges. Butt connection and separation can be completed manually without shutdown and disassembly, effectively reducing equipment idle time and adapting to high-frequency model switching operations of assembly lines.
Self-closing and shut-off design to eliminate medium leakage and waste
Built-in valve core self-closing structure automatically seals and cuts off fluid immediately after pipeline separation, no need to drain medium or block pipe openings in advance. It effectively avoids liquid dripping and gas leakage, suitable for clean workshops, precision testing and valuable medium transportation scenarios.
Long-lasting metal material, superior to rubber quick-plug hoses
The all-stainless steel pipe body has no aging, swelling or cracking problems, with high and low temperature resistance and medium corrosion resistance. It avoids the defects of rubber quick-plug hoses such as easy wear, aging and poor high temperature resistance, and can be used for a long time in high-temperature oil gas, dry gas and clean fluid working conditions.
Long-life plugging cycle, suitable for high-frequency dynamic working conditions
The optimized connector sealing structure supports thousands of repeated plugging operations with stable sealing performance without attenuation or loosening. It is perfectly suitable for mobile equipment, frequently switched pipelines and temporary connection systems, eliminating frequent accessory replacement.
Flexible vibration damping and fatigue resistance to adapt to dynamic displacement
The corrugated flexible structure can compensate for slight equipment movement and minor pipeline offset, absorb unit micro-vibration, avoid stress fatigue caused by rigid connection, protect connectors and equipment interfaces, and reduce failure probability.
Product Applications
1. Precision Testing and Experimental Equipment: Temporary connection of air sources and cooling fluids for test benches, supporting frequent test station switching with fast on-off and zero leakage to ensure experimental accuracy.
2.Mobile Industrial Units: Pipeline connection for mobile air compressors, mobile cooling units and portable oil supply equipment, requiring no tools for equipment shifting.
3.Clean Workshop Fluid System: Transportation of purified water and clean gas in dust-free workshops. The metal material has no precipitation or dust pollution, and quick plug assembly will not pollute the working environment.
4.Assembly Line Model Switching Tooling: Temporary pipelines for automatic production line station switching and tooling commissioning, realizing fast connection and disassembly to meet multi-variety production switching requirements.
5.Small and Medium Temporary Heat Exchange Systems: Temporary connection of hot water and heat transfer oil circulation with stable temperature resistance and convenient disassembly, adapting to phased operation conditions.
6.Equipment After-sales Maintenance Scenarios: Quick on-off for equipment maintenance and temporary pipeline testing with no medium leakage, reducing operation difficulty of maintenance work.
Product Q&A
Q: What is the difference between flexible metal hoses with quick connect fittings and ordinary metal hoses?
A: Ordinary metal hoses adopt fixed flange or thread connections requiring professional tools, with cumbersome and time-consuming disassembly, unsuitable for frequent switching and temporary connection. Flexible metal hoses with quick connect fittings adopt tool-free self-locking quick plug-in design with one-click plugging, rapid locking and plug-and-play use, greatly improving installation and maintenance efficiency. With better flexibility and higher installation tolerance, it effectively adapts to on-site installation deviations and better meets the high-frequency operation and rapid pipe replacement needs of modern automatic equipment.
Q: Can the quick connect metal hose be plugged and unplugged directly under pressure?
A: It supports low-pressure static plugging and unplugging safely within 0–0.8MPa. For high-pressure and pulse impact working conditions, pressure relief is recommended before separation to avoid high-pressure medium impact on the valve core and extend connector service life.
Q: Can flexible metal hoses with quick connect fittings be used for high-pressure gas and hydraulic oil working conditions?
A: Yes. The overall pressure resistance reaches 16MPa. Equipped with a precise self-locking quick plug-in sealing structure, it adapts to high-pressure transmission of compressed air, hydraulic oil, conventional oil and gas media. The impact-resistant and deformation-resistant hose body and stably sealed fittings ensure long-term safe operation of high-pressure fluid systems without leakage or detachment risks.
