Quality You Can Rely On
We follow strict quality control procedures to ensure every quick coupling meets applicable ISO standards and industry requirements. Every product is 100% tested and inspected before shipment, with checks focused on pressure performance, sealing, dimensions, and visual condition.
Material Selection & Treatment
Main metal components are precision-machined from solid bar stock and hardened where required to improve strength and durability. Zinc or zinc-nickel plating is selected according to the product and service environment to improve corrosion resistance, surface quality, and long-term stability.
Testing & Verification
Verification covers pressure testing, sealing testing, dimensional inspection, and visual inspection. Salt-spray testing and material physical and chemical property testing are performed according to product or batch requirements. Every product is 100% tested and inspected before shipment to confirm pressure, sealing, and connection performance.
Process Quality Control
Quality control runs through incoming material confirmation, first-piece inspection, in-process inspection, assembly checks, and final inspection. Key dimensions, heat treatment and plating condition, seal installation, locking function, and appearance are checked at the appropriate stages to support consistent batch quality.
