LYHY All-Copper Quick-Connect Pipe Fitting PET08

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 assembly 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: Utilizes a stainless steel spring-loaded locking mechanism that secures the hose upon insertion, preventing leaks or disconnections even under equipment vibration, thus ensuring stable operation of the pneumatic system. Pressing the lock releases the hose quickly, offering convenient operation.
2. Strict airtightness control: Each fitting undergoes 100% airtight pressure testing before leaving the factory, rigorously controlling leakage issues to ensure compliance with sealing performance standards and reduce the risk of system leaks.
3. Extremely long service life: With a standard plug-and-pull life 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: The nickel-plated brass body boasts outstanding oxidation and rust resistance, capable of handling humid and salt-spray environments. Stainless steel versions are also available, further enhancing environmental adaptability.
5. Full range of specifications in stock: Covering straight connectors, elbows, tees, and more, readily meeting diverse procurement needs while supporting non-standard modifications and OEM manufacturing, along with comprehensive testing and material documentation.

Core Product Value

1. Significantly boosts assembly efficiency: With its tool-free installation design, single-point installation time is reduced from the traditional 60–90 seconds to just 8–15 seconds, increasing whole-machine pipeline assembly efficiency by over 70%, effectively lowering labor costs for manufacturers and shortening equipment delivery cycles.
2. Reduces air consumption and failure risks: Superior sealing performance minimizes system leaks, cutting energy waste, while the vibration-resistant, anti-disconnection design accommodates 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, suitable for equipment across Europe, North America, Southeast Asia, and other regions, providing overseas buyers with products free from adaptation barriers.
4. Meets diverse environmental requirements: Offers two seal material options—NBR and FKM. NBR seals are ideal for typical conditions ranging from –20°C to +60°C, while FKM fluororubber seals handle higher temperatures up to +120°C, ensuring long-term reliability without hardening or failure under varying conditions.
