LYHY All-Copper Quick-Connect Pipe Fitting PDT08-G02

Product Overview

The all-copper quick-connect pipe fitting is a specialized pipeline connector used in pneumatic systems to rapidly join PU/PE/PA pneumatic hoses with valve bodies, cylinders, and air supply lines. It relies on a mechanical snap-lock structure to enable quick insertion and removal of the hose, requiring no tools throughout the process, making operation convenient and efficient. The main body is machined from brass and undergoes high-strength nickel plating. Unlike ordinary zinc-alloy or plastic-lined fittings, its all-metal construction offers superior strength and rigidity, making it a mainstream connection component in automated pneumatic systems. It allows for rapid connections between PU hoses, nylon hoses, and between hoses and valve bodies or cylinders, enabling swift linking of air supply lines. It is widely used in complete equipment assembly, production line upgrades, and pneumatic control systems.

Core Performance Advantages

1. Dual-seal anti-disconnection design: Utilizing a stainless steel spring-loaded locking mechanism, the hose locks upon insertion and remains secure even under equipment vibration, ensuring stable operation of the pneumatic system while allowing quick removal by pressing—a highly convenient operation.
2. Strict airtightness control: Each fitting undergoes 100% airtight pressure testing before leaving the factory, rigorously preventing leakage issues and guaranteeing compliance with sealing performance standards, thereby minimizing the risk of system leaks.
3. Exceptionally long service life: With a standard plug-and-pull lifespan exceeding 10,000 cycles—far surpassing industry norms—this reduces the frequency of spare parts replacement, lowers maintenance workload, and cuts overall usage costs.
4. Excellent corrosion resistance and rust prevention: The nickel-plated brass body boasts outstanding oxidation and rust resistance, capable of handling humid and salt-spray environments, while offering optional stainless steel materials to further enhance environmental adaptability.
5. Full-series stock availability: Covering straight connectors, elbows, tees, and other types, it quickly meets diverse procurement needs, supports non-standard modifications and OEM manufacturing, and provides comprehensive testing and material documentation.

Core Product Value

1. Dramatically improves assembly efficiency: With its tool-free installation design, single-point installation time has been reduced from the traditional 60–90 seconds to just 8–15 seconds, boosting whole-machine piping assembly efficiency by over 70%, effectively lowering labor costs for manufacturers and shortening equipment delivery cycles.
2. Reduces air-source energy consumption and failure risks: Superior sealing performance minimizes system leaks, cutting down on air consumption, while the anti-vibration, anti-disconnection design accommodates the long-term continuous operation of automated equipment, reducing downtime caused by hose disconnection.
3. Adapts to global regional operating conditions: Compatible with mainstream international thread standards such as G, NPT, and PT, with tightly controlled thread tolerances, it fits equipment across Europe, North America, Southeast Asia, and other regions, offering overseas buyers a product choice free from adaptation barriers.
4. Meets diverse environmental requirements: Offering two seal material options—NBR and FKM—NBR seals are suitable for typical conditions ranging from –20°C to +60°C, while FKM fluororubber seals can handle high-temperature environments from –20°C to +120°C, ensuring that seals remain flexible and reliable under varying conditions, thus guaranteeing long-term usability.
