About the TTI TTSFN-5-1B
TTI TTSFN-5-1B is a filter element rated at 1 µm (1 µm nominal), a beta ratio of β ≥ 1000, 150 psid collapse pressure, and measuring 1.75 in OD, 0.78 in ID, and 5.28 in length. It uses Dual Phase Microglass media and Buna-N seals, rated for 250 °F maximum (TTI Elements Catalog 08May24.pdf, p.133).
Application & Compatibility
The TTI TTSFN-5-1B is designed for use in hydraulic and lubrication filtration systems. With a 1µm rating, this element is suitable for servo valve protection and high-precision hydraulic systems. Buna-N seals provide compatibility with standard petroleum-based fluids and mineral oils.
The 150 PSID collapse rating indicates the maximum differential pressure this element can withstand during cold starts or bypass conditions without structural failure. Ensure your system's maximum differential pressure does not exceed this rating.
