Product Overview

The Tube Fitting PP / SUS304 is a robust, precision-engineered connection component designed for reliable fluid transfer in industrial and clean environment applications. It combines the chemical resistance and clarity of polypropylene (PP) with the strength and durability of stainless steel (SUS304), making it ideal for systems where both flow integrity and environmental cleanliness are critical.

Construction and Materials

The body of the fitting is constructed from PP, which offers excellent chemical resistance, high transparency, and suitability in clean environments. The metal components, including structural parts and joints, are made from SUS304 stainless steel, known for its strength and performance in chemical atmospheres. The sealing interface uses EPDM rubber, providing reliable weather, cold, and ozone resistance—though caution is advised due to reduced resistance to mineral oils.

Configuration and Connections

The fitting features multiple connection options including metric threads (M3x0.5, M5x0.8), tapered pipe threads (R1/8, R1/4, R3/8, R1/2), and NPT threads (1/8-27NPT, 1/4-18NPT, 3/8-18NPT, 1/2-14NPT). These standardized interfaces ensure compatibility with a wide range of piping systems and equipment across different industrial setups.

Operating Characteristics

The fitting is rated for a maximum operating pressure of 1.0MPa at temperatures between 0°C and 20°C. It can withstand a maximum vacuum of -100kPa. The standard operating temperature range is from 0°C to 80°C, though when used with the Sealock system, the safe range is limited to 0°C to 60°C to prevent freezing damage.

Sizes and Options

Available in a range of sizes including φ4, φ6, φ8, φ10, and φ12 mm (equivalent to φ1/4", φ3/8", φ1/2"), the fitting offers flexibility for various system requirements. All variants are available in standard colors as per industrial standards, with no copper-based metallic materials used in flow paths to ensure compatibility with non-corrosive or sensitive fluid systems.

Installation and Integration

The product is designed for direct integration into piping systems using the specified threaded connections (metric, NPT, tapered). Installation requires alignment of threads and proper tightening according to standard torque guidelines. No copper-based materials are present in flow paths, ensuring compatibility with non-corrosive fluids and minimizing risk of galvanic corrosion.
