LYHY All-Copper Quick-Connect Pipe Fitting SCT08-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, facilitating swift air line coupling. 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—insertion locks the hose, preventing leaks or disconnection even under equipment vibration, ensuring stable pneumatic system operation, while pressing releases the hose quickly for easy handling.
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 system leak risks.
3. Extremely 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, lowering maintenance workload and overall operating costs.
4. Excellent corrosion and rust resistance: The nickel-plated brass body boasts outstanding oxidation and rust resistance, capable of handling humid and salt-spray environments, with optional stainless steel versions further enhancing environmental adaptability.
5. Full-series stock availability: Covering straight connectors, elbows, tees, and other types, enabling rapid fulfillment of diverse procurement needs, while also 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 piping assembly efficiency by over 70%, effectively cutting labor costs for manufacturers and shortening equipment delivery cycles.
2. Reduces air-source energy consumption and failure risks: Superior sealing performance minimizes system leaks, lowering air consumption, 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, offering overseas buyers a product choice free from adaptation barriers.
4. Meets diverse environmental requirements: Offers two seal material options—NBR and FKM—where NBR seals are ideal for regular conditions ranging from –20°C to +60°C, while FKM fluororubber seals handle high-temperature conditions from –20°C to +120°C, ensuring long-term reliability without hardening or failure under varying conditions.

Solutions to Industry Pain Points

1. Addresses low assembly efficiency of traditional pipe fittings: The tool-free quick-connect design significantly shortens assembly time, reduces labor costs, and resolves the industry’s longstanding pain point of lengthy, inefficient piping assembly in whole-machine factories.
2. Improves frequent air system leakage issues: With 100% airtight testing and dual-seal design, this effectively reduces hose leaks, lowers air consumption, and solves the problem of poor sealing performance and frequent leaks associated with ordinary fittings.
3. Avoids overseas equipment adaptation challenges: Compatible with multiple thread standards such as G, NPT, and PT, with tightly controlled thread tolerances, addressing the issue of ordinary fittings being unable to adapt to overseas equipment across multiple regions and high mismatch rates.
4. Lowers equipment maintenance costs: The exceptionally long plug-and-pull lifespan reduces the frequency of spare parts replacements, solving the problem of short lifespans and heavy maintenance burdens typical of conventional fittings, while the vibration-resistant, anti-disconnection design minimizes downtime losses caused by hose disconnection.
