READ MORETaizhou Jun'an Fire Technology Co., Ltd. is a China-based manufacturer specializing in fire hose fittings and couplings. Located near Shanghai, we produce a full range of quick-connect and threaded couplings for fire protection, irrigation, mining, and industrial fluid transfer. Our factory integrates advanced production equipment with experienced engineering staff, allowing us to deliver standard and custom coupling solutions that meet international performance and safety requirements.
We supply couplings for layflat hoses, double jacket fire hoses, and semi-rigid hoses, ensuring compatibility across our own hose lines and other brands. Our range includes Storz, American, BS Instantaneous, Machino, Italian, GOST, Guilemin/DSP, and Camlock types. Each coupling is manufactured with precision to provide reliable sealing, pressure resistance, and rapid connection in emergency and routine operations.
As a direct Fire Hose Fittings Couplings, Lay Flat Hose Couplings Manufacturers, we control quality from raw material inspection to final testing. We support OEM and ODM projects, offering custom sizes, materials, and branding to match your system specifications.
We produce a wide range of coupling types to suit different regional standards and operational needs. The table below summarizes our main product lines and their typical applications.
| Coupling Type | Key Features | Typical Applications |
|---|---|---|
| Storz Couplings | Quick-connect with internal lugs; no tools required; available in aluminum, brass, or stainless steel. | Fire hydrants, fire trucks, industrial hoses, mining dewatering. |
| American Couplings | Threaded male/female design; meets NFPA standards; high-pressure rating. | Fire protection systems in North America, irrigation, industrial water supply. |
| John Morris / BS Instantaneous | Push-fit locking mechanism per BS336; spring-loaded; quick release. | UK and Commonwealth fire services, municipal firefighting, shipboard systems. |
| Machino Couplings | Robust design with high torque resistance; available in various sizes. | Industrial machinery, high-pressure fluid transfer, agricultural pumps. |
| Italian Couplings | Conforms to Italian standards; lightweight yet durable. | Firefighting and irrigation in Italy and Mediterranean regions. |
| GOST Couplings | Designed to Russian GOST standards; heavy-duty construction. | Fire and industrial systems in Russia and CIS countries. |
| Guilemin/DSP Couplings | Anti-drop locking mechanism; high-pressure sealing. | Emergency firefighting, hydrant connections, high-pressure water systems. |
| Camlock Couplings | Push-lock with cam arms; quick disconnect; available in various materials. | Industrial hose lines, chemical transfer, agriculture, mining. |
We manufacture couplings from aluminum alloy, brass, stainless steel, and other materials depending on the application environment. Aluminum alloy offers light weight and corrosion resistance for general firefighting. Stainless steel provides superior durability in coastal, chemical, and high-pressure environments. Brass is used where high-temperature stability and oxidation resistance are required.
Our production process includes precision casting, machining, and surface treatment. Each batch undergoes dimensional inspection and pressure testing to ensure leak-free performance. We also verify compatibility with standard hose sizes and thread types.
We offer couplings in standard sizes from 1 inch to 8 inches, with options for male/female ends, gaskets, and locking mechanisms. For OEM projects, we can customize the following:
Our engineering team works from your samples or drawings to produce prototypes quickly. We confirm the design before mass production to ensure the coupling meets your system's pressure and flow requirements.
We implement quality control from incoming raw materials to finished goods. Our inspectors check chemical composition and physical properties of materials. During production, we monitor dimensional accuracy and surface finish. Each coupling is tested for pressure resistance and sealing integrity before shipment.
Our factory has passed relevant certifications, and we can provide test certificates upon request. We also conduct field trials for new designs to ensure performance under real-world conditions.
Couplings must match the hose's inner diameter and reinforcement to prevent leaks or blow-offs. We supply couplings that are compatible with our own PVC Layflat Hose, TPU Layflat Hose, and other lines. If you use hoses from other manufacturers, we can adapt the coupling design to fit your existing equipment.
For automated systems, we offer couplings with consistent dimensions and smooth surfaces to work with mechanical handling equipment. We also provide guidance on installation torque and gasket selection to ensure a secure connection.
Proper maintenance extends coupling life. We recommend regular inspection of gaskets and locking mechanisms. Our couplings are designed for easy disassembly, allowing replacement of worn parts without replacing the entire unit. We can supply spare gaskets and springs for field maintenance.
For large projects, we provide installation training and technical documentation. Our after-sales team is available to assist with troubleshooting and replacement parts.
To prepare an accurate quotation and sample, please provide the following details:
With this information, we can recommend the right coupling model and confirm compatibility with your system.
For standard sizes, we often have stock and can ship within days. Custom orders typically require 2-4 weeks for tooling and production, depending on complexity. We provide a confirmed schedule after order confirmation.
Yes, we can reverse-engineer from your sample or drawing. Send us the physical sample or detailed dimensions, and we will produce a matching coupling.
We can provide material certificates and pressure test reports for each production batch. Please specify your requirements in the inquiry.
MOQ depends on the type and size. For standard couplings, MOQ is typically 500 pieces. For custom designs, we may require a higher quantity or a sample fee.
We use precision machining and quality gaskets. Each coupling is hydrostatically tested to a pressure higher than its rated working pressure. We also verify the sealing surface finish to prevent leaks.
Our portfolio also includes - Storz Couplings for applications with different operating ranges, interfaces or integration requirements.
