The French Standard Male Thread Quick Release Coupling stands as a premium industrial solution tailored for high-performance cooling systems across manufacturing and machinery sectors. As a flagship product from Dongguan Tianying Co., Ltd., it strictly complies with NF EN 14420-1 (previously AFNOR) standards, ensuring seamless integration with French-style pipe fittings in critical cooling setups.
Constructed with a nickel-plated brass body, this coupling delivers exceptional resistance to corrosion and wear, making it ideal for prolonged use in wet, high-temperature environments. Its male thread design guarantees compatibility with a wide range of French-manufactured cooling equipment, while the innovative quick-release mechanism enables tool-free connection and disconnection—slashing maintenance time by up to 50% compared to traditional fittings. With a starting weight of 120g for the G1/4" model, it offers unrivaled versatility in space-constrained areas such as mold cavities and machinery enclosures, ensuring reliable coolant flow without compromising on durability.

Designed to meet NF EN 14420-1 requirements, this coupling ensures perfect compatibility with French-manufactured cooling systems, eliminating mismatches in industrial setups. Its parallel G-threads differ from tapered NPT threads by relying on O-ring seals for pressure retention, making it a preferred choice for European machinery and mold cooling applications.
Equipped with a spring-loaded stainless steel sleeve, the coupling allows one-handed operation for swift connections and disconnections. Integrated locking ball bearings engage automatically upon installation, creating a vibration-resistant seal that withstands pressure surges common in high-speed manufacturing environments.
Dual O-ring seals (NBR or FKM) form an airtight barrier, preventing coolant leakage even at maximum pressure of 10 bar and flow rates up to 20 L/min. This feature is critical for protecting sensitive equipment from overheating and maintaining consistent operational efficiency.
Rated for -20°C to 120°C, the coupling handles diverse coolants, including water-glycol mixtures, industrial oils, and refrigerants. The nickel-plated brass body resists degradation from chemical coolants, while FKM seals (when selected) extend usability in high-heat applications.
The low-profile hexagonal nut and smooth sleeve minimize snagging risks in tight spaces, such as mold cavities and CNC machine enclosures. Its lightweight construction reduces strain on flexible hoses, extending their service life and lowering long-term maintenance costs.
Injection molding, blow molding, and die-casting operations depend on precise temperature control to ensure product quality. This coupling facilitates rapid adjustments to coolant flow, enabling quick hose replacements during mold changes and reducing defects caused by inconsistent cooling.
High-speed CNC spindles generate intense heat that can degrade tool performance. The quick-release function allows operators to swiftly connect or disconnect cooling lines, maintaining optimal temperatures to prolong tool life and reduce machining downtime.
Large-scale cooling facilities require reliable, easy-to-maintain connections. This coupling simplifies servicing by enabling fast component swaps, minimizing interruptions in facilities managing high-volume cooling tasks for factories and processing plants.
Auxiliary cooling systems in excavators, forklifts, and industrial vehicles demand secure, vibration-resistant connections. The NF EN 14420-1 compliance ensures compatibility with European-manufactured equipment, while its robust design withstands the rigors of off-road and industrial environments.
Engineered for reliability and efficiency, the French Standard Male Thread Quick Release Coupling is an indispensable component for modern cooling systems, combining compliance, durability, and user-friendly design to enhance operational performance across industries.
