Half-Lock Quick Coupling (ML)
Half Lock Quick Coupling ML is a clean disconnect quick coupling engineered for reliable and leak-free fluid transfer in industrial cooling and liquid circulation systems. Constructed with a high-quality stainless steel body, it offers excellent corrosion resistance, pressure resistance, and long service life in harsh working environments. The semi-locking structure requires two-handed operation during disconnection, providing an additional level of safety confirmation and helping prevent accidental release. Dual external O-rings absorb impact during connection and disconnection while improving sealing stability and reducing wear. The non-drip valve structure minimizes fluid leakage during operation, helping keep equipment and surrounding areas clean and environmentally safe. Multiple thread types and connection options are available to match different piping systems, making Half Lock Quick Coupling ML suitable for cooling systems, industrial fluid transfer, hydraulic equipment, and automated production lines.
The Half-Lock Quick Coupling (ML) features a semi-locking mechanism that balances secure connection with easy disconnection. Designed for efficient fluid transfer, it offers reliable sealing and durability in demanding applications. Ideal for cooling systems, industrial machinery, and precision fluid handling.
