LYHY All-Copper Quick-Turn Pipe Fitting BU08

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 hose insertion and removal, 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 in automated pneumatic systems. 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.
