Full copper quick-connect pipe fitting PGJT08-06

Product Overview

The full copper quick-connect pipe fitting is a specialized pipeline connector used in pneumatic systems to quickly connect PU/PE/PA pneumatic hoses with valve bodies, cylinders, and air supply pipelines. It relies on a mechanical snap-lock structure to enable rapid insertion and removal of the hose, requiring no tools throughout the process, making operation convenient and efficient. The main body of the product is machined from brass material and undergoes high-strength nickel plating on its surface. Unlike ordinary zinc alloy or plastic-lined fittings, this all-metal structure boasts high strength and excellent rigidity, making it a mainstream connection component in automated pneumatic systems. It can achieve quick connections between PU hoses, nylon hoses, as well as between hoses and valve bodies or cylinders, enabling rapid joining of air supply pipelines. It is widely used in complete equipment assembly, production line modifications, pneumatic control systems, and other scenarios.

Core Performance Advantages

1. Dual-seal anti-disconnection design: Utilizes a stainless steel spring clip locking mechanism that locks the hose upon insertion, preventing leaks or disconnections even under equipment vibration conditions, thus ensuring stable operation of the pneumatic system. Pressing the connector allows for quick removal, making operation convenient.
2. Strict airtightness control: Each fitting undergoes 100% airtightness 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 of over 10,000 cycles—far exceeding industry norms—this reduces the frequency of spare parts replacement, lowers maintenance workload on production lines, and cuts overall usage costs.
4. Excellent corrosion resistance and rust prevention: The nickel-plated brass body exhibits outstanding oxidation and rust resistance, capable of handling humid and salt-spray corrosive environments. Stainless steel options are also available, further enhancing environmental adaptability.
5. Full range of specifications in stock: Covering straight connectors, elbows, tees, and other types, quickly meeting diverse procurement needs while supporting non-standard modifications and OEM manufacturing, along with complete testing and material documentation.

Core Product Value

1. Significantly improves 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, boosting whole-machine pipeline assembly efficiency by over 70%, effectively lowering labor costs for manufacturers and shortening equipment delivery cycles.
2. Reduces air supply energy consumption and failure risks: Superior sealing performance minimizes system leaks, cutting air supply energy use, 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/PT, with strict thread tolerance control, suitable for equipment in Europe, America, Southeast Asia, and other regions, offering overseas buyers products without adaptation barriers.
4. Meets diverse environmental requirements: Offers two seal material options—NBR and FKM. NBR seals are suitable for regular conditions ranging from ‑20℃ to +60℃, while FKM fluororubber seals can handle high-temperature conditions from ‑20℃ to +120℃, ensuring long-term reliability by preventing seal hardening or failure under different operating conditions.
