The Tube Fitting Stainless SUS303 like Corrosivity Series is a push-in fitting designed for reliable fluid connections in corrosive or humid environments. Its primary purpose is to provide secure, leak-free joints between tubing and pipe systems while maintaining durability under varying operational conditions.
The fitting's main metal components are constructed from a special stainless steel that offers corrosion resistance equivalent to SUS303. The resin parts are made from PBT, a standard material suitable for general environmental exposure. The sealing component uses HNBR rubber, which provides enhanced ozone resistance through hydrogen addition to NBR and is ideal for low-concentration ozone environments.
The fitting features a push-in design with connection options including metric threads (M5x0.8, M6x1) and tapered pipe threads (R1/8, R1/4, R3/8, R1/2). These interfaces allow compatibility with a range of standard piping systems and tubing configurations.
The fitting is rated for a maximum operating pressure of 1.0MPa and can withstand a maximum vacuum of -100kPa. It operates effectively within a temperature range of 0 to 60℃, ensuring performance under normal ambient conditions without freezing risks. Fluid media supported include air and water (conditional).
Available in multiple sizes including φ4, φ6, φ8, φ10, φ12, and φ16 mm, the fitting offers flexibility for various system designs. Thread options include M5x0.8, M6x1, R1/8, R1/4, R3/8, and R1/2, enabling integration with different piping standards.
The fitting is designed without any copper-based metallic material in the flow path, ensuring compatibility with systems sensitive to copper leaching. It meets clean-wash specifications through vacuum ultrasonic cleaning using HFE in a clean room environment, followed by deaeration packaging.
