The Tube Fitting PP / SUS303 like Corrosivity Series is a cost-effective, corrosion-resistant tube fitting designed for applications requiring reliable performance in clean environments. It combines the chemical stability of polypropylene with the corrosion resistance equivalent to SUS303 stainless steel, making it ideal for use in systems where exposure to moisture or mild chemicals is expected without compromising durability.
The fitting features a PP (polypropylene) resin body, which provides excellent chemical resistance, high transparency, and suitability for clean environments. The internal structure uses a stainless steel equivalent material with corrosion resistance comparable to SUS300, ensuring long-term integrity in corrosive conditions. No copper-based metallic materials are used in the flow path, eliminating potential contamination risks.
The fitting is sealed using EPDM rubber, which offers excellent weather resistance, cold resistance, and ozone resistance. However, it has limited resistance to mineral oils and should not be exposed to such substances. For applications involving low concentration ozone, HNBR or FKM seal materials are used in certain variants—note that compatibility may vary depending on the specific product model and flow path usage.
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, and operates effectively within a temperature range of 0 to 80°C, with no freezing risk. The fluid medium compatibility includes air, water, and other chemicals under conditional use.
Available in standard sizes suitable for common tube systems, the fitting is designed with consistent dimensions for easy integration into existing piping setups. While color options are not specified, the transparent PP body allows visual inspection of internal components. Specific variants may differ in seal material composition depending on exposure conditions and flow path requirements.
Installation requires no lubrication during assembly—this is a non-grease, oil-free specification ensuring compatibility with clean environments and reducing contamination risk. The design supports direct integration into systems where minimal maintenance and high reliability are required, particularly in applications involving air or water transport under standard pressure conditions.
