READ MOREAs a John Morris Couplings/BS Instantaneous Couplings Manufacturers, we match product configuration to the application, operating limits, interfaces and acceptance criteria defined for each project.
As a specialized John Morris Couplings/BS Instantaneous Couplings manufacturer in China, Taizhou Jun'an Fire Technology Co., Ltd. produces quick-connect couplings that meet British Standard BS336. Our range covers sizes from 1-1/2" to 6", in brass or aluminum alloy, designed for firefighting, industrial, and marine applications where fast, reliable hose connections are critical.
We combine modern production equipment with experienced engineers to deliver couplings that lock instantly, seal under high pressure, and withstand harsh environments. Whether you need standard configurations or custom OEM/ODM designs, we provide consistent quality and on-time delivery.
Our BS instantaneous couplings are available in both male and female ends, with options for hose tails, caps, and adapters. They are used to connect fire hoses to pumps, hydrants, nozzles, and other equipment in municipal fire services, industrial plants, airports, and ships.
| Size | Material | Typical Use |
|---|---|---|
| 1-1/2" | Brass / Aluminum | Light-duty firefighting, industrial lines |
| 2.5" (65mm) | Brass / Aluminum | Standard fire hose connections |
| 4" | Aluminum | High-flow water supply, hydrant systems |
| 6" | Aluminum | Large-diameter relay lines, industrial deluge |
Our couplings are manufactured from high-strength aluminum alloy or brass, chosen for their corrosion resistance and durability. The sliding locking mechanism ensures a secure connection with a simple push, while precision sealing rings prevent leaks even under fluctuating pressures.
Every coupling undergoes rigorous inspection during production, including dimensional checks, pressure testing, and material verification. Our factory follows strict quality control procedures, from incoming raw material analysis to final functional tests, ensuring each unit meets the required standards.
We provide test certificates and material documentation upon request, supporting your project acceptance and audit requirements.
We understand that different markets and applications may require specific configurations. Our team can customize couplings in terms of size, material, color, and packaging. We also offer OEM services, producing couplings under your brand with your logo and labeling.
From prototype to mass production, we follow a structured process: consultation, requirement definition, sample creation, order confirmation, production, inspection, and shipping. This ensures your specifications are met accurately.
BS instantaneous couplings are designed for quick connection without tools. To maintain performance, regularly inspect the locking mechanism and replace worn gaskets. Our couplings are easy to disassemble for cleaning or part replacement, reducing downtime.
We provide installation guidelines and maintenance recommendations with each shipment, and our technical team is available for support.
To prepare an accurate quotation and configuration, we need the following details from you:
With this information, we can recommend the most suitable coupling configuration and provide a detailed proposal.
In addition to BS instantaneous couplings, we manufacture a full line of fire hose couplings, including Storz Couplings, American Couplings, and Machino Couplings. Our range also includes layflat hoses and nozzles to provide complete firefighting solutions.
