  【RME】 Quick Coupling for Railway Cooling In vehicle-mounted cooling circuits, 【RME】 specializes in the railway industry and offers superior airtightness. It is designed so that sealing occurs before the valve opens during connection. The materials used are durable, and corrosion resistance is enhanced in the presence of liquids and coolant additives. Additionally, a protective cover is available to shield the sealing area and locking mechanism from external factors such as water and dust. <Application>: - Cooling circuits for vehicle-mounted electronic devices, engines, inverters, and converters - For filling and draining <Nominal Diameter DN>: 6mm to 25mm <Maximum Allowable Pressure>: 16bar <Composition>: Brass, stainless steel (surface treatment) <Other>: Chloroprene protective cover

  【RTD】 Full Flow Coupling for Railways Intense vibrations, frequent acceleration and deceleration, extreme temperatures. Even under such harsh conditions, the 【RTD】 can be used as a quick coupling for compressed air. To achieve this, the sealing parts and the locking mechanism, which is a movable component, are covered with a protective cover, made from high-quality materials, designed for durability, and feature a semi-automatic locking system based on ergonomic design for ease of handling. The connection guide on the plug side is set longer to ensure secure attachment and detachment while maintaining sealing performance even under the influence of vibrations. <Application>: Connection of compressed air between the body and bogie, and between vehicles. <Nominal Diameter DN>: 11mm, 19mm <Maximum Allowable Pressure>: 10bar <Composition>: Mainly stainless steel, with a protective cover on the socket side. <Other>: Can be used in combination with metal hoses or flexible hoses.

• 

  【SPI】 Clean Break Coupling for Railways The 【SPI】 is a non-spill coupling featuring a flat face design, which eliminates liquid drips during connection and disconnection, preventing foreign matter from entering the circuit. The guide section for the plug connection is designed to be longer, ensuring reliable connections even under harsh conditions. The ball lock mechanism allows for easy, quick, and secure locking, and is resistant to harsh conditions such as vibrations and oscillations. <Application> - Hydraulic brake circuits - Hydraulic tilt circuits - Brake calipers - Hydraulic accumulators - Hydraulic units <Nominal Diameter DN>: 3mm to 12mm <Maximum Allowable Pressure>: 160 bar <Materials>: Mainly stainless steel, brass with plating treatment <Other>: Can be used in combination with metal hoses or flexible hoses.

  【SPT/CG】 Non-spill coupling for railway cooling It features a non-spill structure with a flat face design. Therefore, there is no air intrusion (air entrapment) in the circuit during connection, and there is no liquid dripping during disconnection. It is made of aluminum alloy with surface treatment, providing sufficient strength while being lightweight. Its internal structure optimizes the flow path while keeping the overall size as compact as possible, reducing pressure loss. Emphasizing safety and reliability, it has a robust locking mechanism. <Application>: - Cooling circuits for onboard electronic devices, engines, inverters/converters - For filling and draining <Nominal diameter DN>: 5mm to 25mm <Maximum allowable pressure>: 40bar <Composition>: Aluminum alloy (surface treated) <Other>: A pressure relief valve can be optionally added to the socket or plug. It protects the circuit when the pressure continues to rise due to residual heat.

• 

  【SPI/OS】 Full flow coupling designed for use in harsh environments It excels in impact resistance, and its performance is not compromised even under the most severe conditions. The sealing and locking parts are completely covered, further enhancing safety. The locking mechanism sleeve is ergonomically designed for ease of use, allowing for a firm grip even while wearing work gloves. It can be used for pneumatic applications between the vehicle body and bogie, as well as between vehicles, and can be safely used in physically demanding environments such as those with acceleration, vibration, and low temperatures. <Application>: - Compressed air applications in the railway industry - Pneumatic applications between the vehicle body and bogie, and between vehicles <Nominal Diameter DN>: 6mm, 9mm <Maximum Allowable Pressure>: 10bar <Composition>: Mainly stainless steel, with a rubber cover on the socket <Other>: Can be used in combination with metal hoses or flexible hoses.
