John Morris Fire Hose Couplings and Adaptors

This image series showcases ​John Morris​ fire hose couplings and adaptors, featuring ​9 core coupling models​ and ​3 standard single-ear type adaptors, all compliant with the international ​BS336 standard. Designed for rapid connection of fire hoses, pump valves, and piping systems, the products are categorized as follows:
1. Main Coupling Models (9 Types)
Crafted from ​brass, the couplings are arranged in two rows and include straight, branch, and thread adaptor types:

1.​LT-001: Inlet 2.5" BS336 (Imperial) → Outlet Φ63.5mm (Metric, compatible with 65mm hose)
2.​LT-002: Inlet 2" BS336 → Outlet Φ51mm (compatible with 50mm hose)
3.​LT-003: Inlet 1.5" BS336 → Outlet Φ38mm (compatible with 40mm hose)
4.​LT-004: Inlet 2.5" BS336 → Outlet Φ51mm (large-to-small diameter conversion)
5.​LT-005: Inlet 2.5" BS336 → Outlet Φ38mm (large-to-small diameter conversion)
6.​LT-006: Inlet 2" BS336 → Outlet Φ38mm (medium-to-small diameter conversion)
7.​LT-007: Inlet 2.5" BS336 → Outlet ​F2.5" BSP​ (Female British Standard Parallel Thread for pump/valve connection)
8.​LT-008: Inlet 2.5" BS336 → Outlet ​2.5" BSP​ (Male British Standard Parallel Thread)
9.​LT-009: Inlet 2.5" BS336 → Outlet ​1.5" BSP​ (large diameter to small thread adaptor)

2. Single-Ear Type Brass Adaptors (Female)
Three standard specifications designed for quick connection, featuring a single-ear locking mechanism and brass construction:

•​65mm Adaptor: Complies with BS336 2.5", actual diameter 63.5mm (compatible with 65mm hose)
•​50mm Adaptor: Complies with BS336 2", actual diameter 51mm (compatible with 50mm hose)
•​40mm Adaptor: Complies with BS336 1.5", actual diameter 38mm (compatible with 40mm hose)

3. Design and Functional Features

1.​High Compatibility: Supports Imperial (inch), Metric, and BSP thread standards, meeting global equipment requirements.
2.​High-Pressure Resistance: Brass construction ensures corrosion resistance and pressure-bearing capability for firefighting high-pressure applications.
3.​Quick Connection: Single-ear design (John Morris style) enables rapid locking and disassembly of hoses and pump valves.
4.​Conversion Flexibility: Provides diameter conversion (e.g., 2.5" to 38mm) and thread conversion (e.g., BS336 to BSP) to resolve interface mismatches.

4. Applications
Ideal for fire truck pump systems, industrial fire protection networks, mobile firefighting equipment, and hose extension connections. These components are critical for efficient emergency rescue operations.
Through this product portfolio, John Morris achieves standardization and flexibility in firefighting connections, enhancing on-site operational efficiency.
