Junkosha Stainless Steel Fitting U2S Series Union 6 x 4 mm U-0640-US2 1 pc

Catalog number: U-0640-US2 Features: ● Stainless steel fittings compatible with flexible tubes such as polyurethane tubes and THV tubes. ● To prevent the tube from twisting out, a cap nut with a built-in sleeve (originally developed by Junkosha) is used. ● No need to manage the tightening torque of the cap nut. Applications: ● For piping of corrosive fluids ● For hydraulic piping ● For rust-prevention piping Specifications: ● Compatible tube outer diameter D (mm): 6 ● Hexagonal side length (mm): 12 ● Compatible tube outer diameter D1 (mm): 6 ● Compatible tube outer diameter D2 (mm): 6 ● Fluid temperature (℃): Air: -20 to 60℃, Water: 0 to 50℃, Fluorine-based refrigerant liquid: 0 to 50℃ ● Fluid used: Air, water, Fluorine-based refrigerant liquid ● Hexagonal side length (mm) Mounting nut: 12 ● Hexagonal side length (mm) Body: 12 ● Compatible tube inner diameter (mm): 4 ● Fluid used: Air, water, Fluorine-based refrigerant liquid ● Fluid temperature: Air: -20 to 60℃, Water: 0 to 50℃, Fluorine-based refrigerant liquid: 0 to 50℃ ● Maximum High operating pressure: Complies with the maximum operating pressure of the tube. Operating vacuum pressure: 0.014 kPa or more. Applicable tube (when the fluid is air): Polyurethane tube (US, UH, UF, UFL, UE, UC), multi-layer tube (UP1). Applicable tube (when the fluid is water): Polyurethane tube (UF, UFL), multi-layer tube (UP1). Applicable tube (when the fluid is fluorinated refrigerant): Polyurethane tube (US, UH, UF, UFL, UE, UC), multi-layer tube (UP1). Material/Finish: Stainless steel (SUS316). Note: If the operating temperature range of the tube is within the operating temperature range of the fitting, the operating temperature range of the tube should take priority.
