【Product Overview】

The Plug and Pull Type Quick Connector Metal Hose is a quick-install stainless steel corrugated pipe designed for industrial high-pressure fluid conveying, integrating flexible compensation, vibration damping and quick connection. It solves common pain points of traditional high-pressure pipelines, such as cumbersome welding, difficult disassembly, sealing leakage, and long downtime for maintenance. The product is divided into three types according to internal structure: KA through type, KB single self-sealing type, and KC double self-sealing type, which can be flexibly selected according to pipeline working conditions. The connector adopts a standardized design with strong interchangeability, and the stainless steel braided outer layer enhances pressure resistance, making it suitable for small-diameter high-pressure fluid conveying. It can be quickly disassembled and assembled without tools, greatly improving equipment maintenance and pipeline renovation efficiency, making it an ideal flexible connection fitting for hydraulic, pneumatic and high-pressure fluid pipelines.

【Three Types Description】

1. KA Through Quick Connector: No self-sealing structure with straight-through flow, low flow loss, suitable for scenarios where both ends of the pipeline are depressurized and there is no risk of residual media. Fast disassembly and assembly, suitable for frequent on-off low/medium pressure pipelines.
2. KB Single Self-Sealing Quick Joint: Built-in self-sealing valve at one end, which can automatically close one end of the pipeline when disconnected to prevent medium leakage. Suitable for scenarios where the pipeline is depressurized at one end and pressurized at the other. No medium overflow during disassembly, reducing pollution and safety risks.
3. KC Double Self-Sealing Fast Joint: Built-in self-sealing valves at both ends, which automatically close both ends when disconnected, completely preventing medium leakage. Suitable for scenarios where both ends of the pipeline are pressurized and medium leakage is not allowed. The preferred type for high-pressure fluids and toxic/volatile media conveying.

【Product Structure & Core Material Description】

1. Inner Stainless Steel Corrugated Tube: Precisely formed from high-quality stainless steel with good flexibility and flex fatigue resistance, effectively compensating for pipeline thermal expansion and contraction displacement and buffering equipment operation vibration, suitable for frequent deformation in high-pressure pipelines.
2. Outer Stainless Steel Braided Mesh: High-density stainless steel wire braided layer greatly enhances the tensile, impact and pressure resistance of the hose, protecting the inner corrugated tube from external wear. It can withstand a maximum working pressure of 12.5MPa, preventing bursting and cracking, suitable for high-pressure conditions.
3. Plug and Pull Quick Connector: Standardized quick connection structure, which can be locked by hand without tools. Built-in high temperature and high pressure resistant seals, zero leakage after locking, and can be reused for multiple disassembly and assembly. The connector is highly interchangeable and compatible with standard quick connectors of the same specification.
4. Material and Thread Customization: Default Rc thread, supporting customization of other thread specifications such as NPT on request. Made of stainless steel, corrosion and high pressure resistant, suitable for various industrial fluid media.

【Core Technical Parameters & Pressure Table】

• Applicable Media: Industrial liquids, gases, hydraulic oil and other conventional fluids
• Working Temperature: -20℃~400℃ (adjustable according to seal material)
• Customization: Non-standard threads such as NPT, special lengths and customized pressure grades are available.

【Core Performance Advantages】

1. Tool-Free Plug-and-Play Installation, High Maintenance Efficiency: No welding or wrenches required, quick disassembly and assembly by hand, greatly shortening equipment maintenance and pipeline renovation time, reducing downtime costs.
2. Three Types Available, Full Working Condition Adaptability: KA through, KB single self-sealing, KC double self-sealing structures, adapting to different pressurized/depressurized scenarios to meet diverse sealing needs of high-pressure pipelines.
3. High Pressure and Impact Resistant, Safe and Explosion-Proof: Reinforced by stainless steel braided mesh, with a maximum pressure resistance of 12.5MPa, excellent impact and burst resistance, eliminating leakage and bursting risks of high-pressure pipelines.
4. Self-Sealing and Leak-Proof, Environmental Protection and Safety: KB/KC types with built-in self-sealing valves automatically close the pipeline when disconnected, preventing medium overflow, reducing pollution and safety risks, suitable for toxic and volatile media.
5. Strong Interchangeability, High Versatility: Standardized connector design, compatible with industry standard quick connectors of the same specification, no additional adaptation required for replacement and installation, convenient maintenance.
6. Stainless Steel Material, Corrosion Resistant and Long Service Life: Overall stainless steel material, acid and alkali resistant, high temperature resistant and anti-aging, no rust or leakage during long-term use, with a service life far exceeding ordinary hoses.

【Main Application Scope】

• Hydraulic and Pneumatic Systems: High-pressure hydraulic oil and compressed air conveying pipelines, flexible connections for equipment power units.
• Industrial Equipment Maintenance: Pipelines requiring frequent disassembly and assembly, such as machine tools, air compressors, and hydraulic/pneumatic circuits of construction machinery.
• Chemical and Fluid Conveying: High-pressure liquid and gas media conveying, KB/KC types can be used in scenarios preventing medium leakage.
• Temporary Pipeline Connection: Emergency repair and temporary equipment docking, quickly building high-pressure fluid conveying pipelines.
