  • Premium Aluminum Oil Level Sight Glass with Black Oxide Finish

    The Fanovo FSG011 series is an elite aluminum oil level sight glass treated with a high-durability Black Oxide Finish to provide exceptional anti-corrosion protection and a sleek aesthetic. Beyond our standard premium aluminum body, this high-visibility sight window can be fully customized and manufactured in other high-strength materials, such as Stainless Steel (316L/304), Brass, or exotic alloys. Pricing is highly flexible and will be accurately quoted based on your specific custom material and structural requirements.

    Zero MOQ & Flexible Tooling/Reflector Options: To fully support our industrial B2B partners and procurement managers, we offer No Minimum Order Quantity (Zero MOQ) restrictions for this series, making it easy to run small batch qualifications or initial trial orders. The internal fluid reflection baffle/reflector features our standard, optimized fixed-mold shape for immediate high-contrast visibility. However, we can fully customize the reflector shape, design, and dimensions straight from your engineering drawings.

    Comprehensive Engineering Specifications:

    • Versatile Sizing Matrix: Available in an extensive range of sizes from 1/8 inch up to 6 inches, ensuring a perfect fit for tiny hydraulic reservoirs to massive industrial gearboxes.

    • Custom Thread Engineering: Precision CNC-machined threads are fully customizable, seamlessly supporting NPT, BSP, BSPT, G, or specialized metric threads.

    • High Pressure Resilience: Depending on your unique customization parameters and window thickness, this robust oil level indicator can effortlessly handle working pressures up to 500 PSI.

    • Global Industrial Compliance: Engineered for critical piping systems and international projects, our sight glasses can be manufactured to strictly conform with global standards, including DIN standard, ANSI 150 sight glass, EN1092 sight glass, JIS 10K sight glass, and ISO sight glass specifications.

    Widespread Industrial Applications:

    Due to its heavy-duty construction and deep customization flexibility, this dome-and-window indicator features an exceptionally wide range of applications. It is widely utilized across automotive coolant lines, industrial compressors, agricultural equipment, chemical processing units, marine piping, and heavy-duty mechanical engineering networks worldwide.
