Tube fittings made from stainless steel - SUS316, SUS304, SUS303 are high-performance connectors prized for superior corrosion resistance, chemical inertness, and suitability for high-purity, high-temperature, or harsh environments like chemical, pharmaceutical, and food processing industries. They offer strong, leak-free connections, available in various designs (push-to-connect, compression, double-ferrule) for different tubing (nylon, PU, fluororesin), providing excellent airtightness from vacuum to high pressure, often with features for cleanliness and reliability.
