LYHY All-Copper Quick-Connect Pipe Fitting PMT08

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 entire process, making operation convenient and efficient. The main body of the product 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 can achieve rapid connections between PU hoses, nylon hoses, as well as between hoses and valve bodies or cylinders, enabling swift linking of air supply lines. It is widely applied in complete equipment assembly, production line upgrades, pneumatic control systems, and other scenarios.

3. Exceptionally long service life: With a standard plug-and-unplug lifespan exceeding 10,000 cycles—far surpassing industry norms—this reduces the frequency of spare parts replacement, lowers production line 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 specifications available in stock: Covering straight connectors, elbows, tees, and other types, quickly meeting procurement needs across various scenarios, while also supporting non-standard modifications, OEM manufacturing, and providing 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-source energy consumption and failure risks: Superior sealing performance minimizes system leaks, cutting down on air consumption, while the vibration-resistant, 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, suitable for equipment in Europe, North America, Southeast Asia, and other regions, providing overseas buyers with product choices free from adaptation barriers.
4. Meets diverse environmental requirements: Offering two seal material options—NBR and FKM—NBR seals are ideal for regular conditions ranging from –20°C to +60°C, while FKM fluororubber seals can handle high-temperature conditions from –20°C to +120°C, ensuring that seals remain flexible and reliable under varying environmental conditions, thus guaranteeing long-term usability.
