LYHY All-Copper Transition Fitting CEFT-02

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 relies on a mechanical snap‑lock 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.

Key Product Advantages

1. Dual‑seal anti‑disconnection design: Utilizes a stainless steel retaining ring to lock the hose, featuring a double‑sealing structure that effectively prevents air leaks and hose disconnection even under vibration, ensuring stable operation of the pneumatic system.
2. Strict factory quality control: Each fitting undergoes a 100% air‑tightness pressure test, rigorously controlling leakage at the source to ensure compliance with sealing performance standards and reduce the risk of pipeline failures.
3. Exceptional service life and safety margin: With a plug‑and‑play life of ≥5,000 cycles and a burst pressure of ≥4 times the working pressure, it provides ample safety margin, meeting the demands of long‑term continuous operation in automated equipment and reducing the frequency of replacements.
4. Oxidation resistance and corrosion protection: The brass body with nickel plating effectively resists oxidation and rust, suitable for humid and corrosive environments. Additionally, offering both NBR and FKM sealing options, these materials remain flexible and perform reliably across varying conditions—NBR seals are ideal for –20°C to +60°C, while FKM fluororubber seals withstand –20°C to +120°C, catering to a wider range of application scenarios.
5. Tool‑free, efficient installation: Quick plug‑and‑play installation requires no tools; simply insert the hose to lock it, minimizing human error during assembly and ensuring consistent pipeline connections. Installation time per joint has been reduced from 60–90 seconds to 8–15 seconds, boosting overall pipeline assembly efficiency by over 70% and significantly cutting labor costs and equipment delivery timelines.
6. Convenient maintenance and debugging: Pressing the fitting releases the hose, making disassembly and reassembly easy during production line adjustments or equipment maintenance, thereby reducing downtime and improving maintenance efficiency.
7. Comprehensive specification coverage: Includes straight fittings, elbows, tees, crosses, reducers, flow regulators, and threaded straight fittings, compatible with international G/NPT/PT threads. Thread tolerances are strictly controlled at 6H/6g, ensuring strong interchangeability and compatibility with equipment from Europe, Southeast Asia, and beyond, thus reducing selection mismatches.
8. Multiple material options: In addition to copper with nickel plating, stainless steel variants are also available, addressing more demanding operating conditions such as humidity and salt‑spray corrosion.
