LYHY All-Copper Quick-Turn Pipe Fitting BE-08

Product Overview

The all-copper quick-turn pipe fitting is a core pipeline connector in pneumatic systems, specifically designed for rapidly connecting PU/PE/PA pneumatic hoses to valve bodies, cylinders, and air supply lines. It utilizes a mechanical snap-lock structure to enable tool-free, quick insertion and removal of hoses, offering convenient and efficient operation. The main body is machined from brass and undergoes high-strength nickel plating. Unlike zinc-alloy or plastic-lined fittings, its all-metal construction provides superior strength and rigidity, making it the mainstream connection component for automated pneumatic circuits. The product line covers a full range of specifications, including straight connectors, elbows, tees, crosses, reducers, flow control valves, and threaded straight connectors, compatible with various overseas thread standards such as G, NPT, and PT, meeting diverse pneumatic circuit connection needs. It is widely used in automated equipment, textile machinery, packaging equipment, and pneumatic circuits supporting construction machinery.

3. Extremely long service life: With a plug-and-pull life exceeding 10,000 cycles and a burst pressure of at least four times the working pressure, ample safety margin reduces the frequency of replacements and lowers overall customer costs.
4. Corrosion-resistant and durable: The nickel-plated brass body resists oxidation and rust, suitable for humid and salt-spray environments. Two seal options—NBR and FKM—are available, ensuring that seals remain flexible and effective across different operating conditions.
5. Comprehensive specification coverage: Straight connectors, elbows, tees, crosses, reducers, flow control valves, and threaded straight connectors are all stocked and readily available, compatible with international mainstream threads G/NPT/PT, offering strong interchangeability and adapting to equipment from Europe, Southeast Asia, and other regions, minimizing selection mismatches. Thread tolerances are strictly controlled at 6H/6g.
6. Tool-free convenience: Insert the hose to lock it, press to release it—no additional tools required. This boosts assembly efficiency, saves labor hours, reduces human error, and ensures consistent pneumatic circuit assembly. It also simplifies production line debugging and equipment maintenance, reducing downtime losses.
7. Supports non-standard modifications and OEM manufacturing: Custom modification services are available upon request, along with OEM orders. Complete testing and material documentation can be provided to meet compliance requirements for special projects such as food processing and new energy applications.
