LYHY All-Copper Transition Fitting BZ-G02

Product Overview

The all-copper transition fitting is a quick‑connect pneumatic pipeline connector, specially designed for pneumatic systems to rapidly join PU/PE/PA pneumatic hoses with valve bodies, cylinders, and air supply lines. Made entirely from brass and finished with high‑strength nickel plating, this fitting differs from zinc‑alloy or plastic‑lined connectors. Its all‑metal construction offers superior strength and rigidity, making it the mainstream connection component in automated pneumatic systems. It utilizes a mechanical snap‑in mechanism for quick hose insertion and removal without additional tools, enabling rapid connection of air supply lines. Widely used in complete equipment assembly, production line upgrades, and pneumatic control systems, it covers a full range of specifications including straight fittings, elbows, tees, crosses, reducers, flow regulators, and threaded straight fittings. It accommodates various international thread standards such as G, NPT, and PT, meeting the connection needs of diverse pneumatic systems.
