SUS316 Tube Fittings

Technical Specifications

• Fluid Media Compatibility: Air, Water, and other conditional chemicals.
• Maximum Operating Pressure: 1.0 MPa for push-in models, or subject to the tube's limit for compression styles.
• Maximum Operating Vacuum: -100 kPa across both configurations.
• Operating Temperature Range: -5 to 150°C for push-in variants, or bounded by tube specifications without freezing.
• Water Application Limits: Surge pressures must be controlled below the maximum rating, with liquid use limited to non-reactive substances.

Material Profile & Construction

• Main Metal Component: SUS316 Stainless Steel utilized for all structural parts to provide premium corrosion resistance.
• Seal Rubber Matrix: Standard with FKM (Fluororubber) or HNBR options for top-tier chemical, heat, and ozone protection.
• Tube Retention System: Precision-engineered Lock-Claws matching the standard series for tool-free, high-reliability operation.
• Eco-Conscious Design: Built with a copper-free flow path to suit sensitive processing setups.
• Lubrication Baseline: Assembled standard as completely oil-free with zero internal grease application.

Custom Variants & Manufacturing Codes

• Sleeveless Compression Models: Built with a re-usable sleeveless format to prevent missing sleeve hazards during assembly.
• Cleanroom Production Packaging: Available via special code suffix, indicating the components are blown with clean air and enclosed in an ISO Class 6 cleanroom.
• Safety Standard Alignment: Internal flow paths utilize compounds fully compliant with the Japanese Food Sanitation Act.

• Metallic Body: SUS316 stainless steel.
• Threaded Metallic Body: SUS316 stainless steel.
• Release Ring: SUS316 stainless steel featuring an integrated fluorine coating.
• Lock Claws (Internal): SUS316 stainless steel, providing the internal grip for the tubing.
• Guide Ring: SUS316 stainless steel.
• Elastic Sleeve & O-Ring: FKM (Fluorine rubber) with an added fluorine coating for high chemical resistance.
• Metric (M) Thread Gasket: SUS316 + FKM laminate composite.

⚠️ Crucial Specification Notes from Pisco

• No Thread Sealant: Unlike standard models, no Sealock coating is pre-applied to the tapered pipe threads on the SUS316 series.
• Copper-Free: Zero copper-based metallic materials are used in the fluid flow paths, making them ideal for semiconductor, medical, and food-related systems.
