The self-developed GTP series pressure test point push-in connectors, featuring excellent sealing performance, corrosion resistance, compact design, and high reliability, have undergone more than two years of rigorous validation under real operating conditions. With consistently outstanding and stable performance, they have now been successfully deployed at scale in rail transit trains, applied in braking systems and tread cleaning auxiliary systems, earning strong customer trust.
For a long time, pressure test point push-in connectors have been subject to extremely stringent requirements for reliability and safety. Without proven long-term performance in real-world conditions, it is difficult for such components to enter the core application scenarios of rail transit.
The GTP series has now achieved large-scale onboard deployment, establishing itself as a benchmark product among critical components. This milestone also lays a solid foundation for further expansion into the rail transit market.
Rail Transit Solution for Push-in Connectors
Based on comprehensive type testing and extensive real-world application scenarios, the GTP series push-in connectors have been developed to meet the needs of pressure test points, simulation measurement, and compressed air applications in the rail transit industry.
Designed specifically for the unique requirements of rail pressure test points and simulation measurements, the GTP series emphasizes practicality and reliability. Each core performance attribute is engineered to address real-world challenges and validated through measurable parameters:
-
Long-term Safety and Reliability
Adaptable to a wide temperature range, resistant to repeated insertion and removal, compatible with various media, resistant to contamination, and anti-aging. These features effectively extend service life under complex environmental conditions, ensuring efficient and continuous operation and maintenance. -
Robust Vibration Resistance
Vibration and shock performance meet stringent standards for airborne, vehicle-mounted, and marine applications, ensuring secure connections without loosening or leakage risks during long-term train operation and continuous vibration conditions. -
Corrosion-resistant Design
The housing passes rigorous salt spray testing, effectively withstanding humid, saline, and alkaline environments, thereby extending component lifespan under harsh climatic conditions. -
Convenient One-handed Operation
A uniquely designed raised button enables easy connection and disconnection, significantly improving maintenance efficiency in confined spaces.
Backed by seven R&D and manufacturing bases and four major technology platforms, a comprehensive technical system has been established, covering the entire process from R&D and production to operation, maintenance, and delivery. Through systematic R&D testing capabilities and precision manufacturing processes, the stringent requirements of rail transit—safety, reliability, and durability—have been translated into every product feature, enabling a solid leap toward large-scale application of component products in the rail transit sector.
Looking ahead, with the mission of “managing every degree,” the company will continue to leverage robust materials science, precision engineering, and testing systems in the field of quick connectors, supporting China’s high-end manufacturing and providing safe, reliable, and intelligent fluid connection solutions for industries such as rail transit, data centers, and energy storage thermal management.
