Can Hydraulic Oil Level Sight Glass AWO1 be installed on angled or curved tank walls and still provide clear side visibility?

Yes. Hydraulic Oil Level Sight Glass AWO1 can be installed on angled or curved tank walls and still provide clear side visibility. Its spherical polyamide viewing opening is specifically designed to offer clear sight not only from the front but also from lateral angles, making level checks faster and more convenient on non-flat surfaces. The robust aluminum body and supplied guarnital fiber washer ensure a reliable seal against mechanical stress and potential leaks when mounted on varied wall geometries. Choose the appropriate diameter D [mm] to match your tank curvature and opening size; operating temperature range 0°C to +80°C supports typical hydraulic environments.

Can Hydraulic Oil Level Sight Glass AWO1 withstand continuous exposure to temperatures near its upper limit (+80°C) without discoloration or loss of transparency?

Hydraulic Oil Level Sight Glass AWO1 can withstand continuous exposure to temperatures near its upper limit (+80°C) without significant discoloration or loss of transparency, provided normal operating conditions are maintained. The product description specifies an operating temperature range of 0°C to +80°C and highlights a polyamide inspection opening noted for excellent transparency and long-lasting clarity. The robust aluminum body and proper sealing with a guarnital fiber washer support durable performance at the specified temperatures. However, continuous exposure at or very close to the upper limit may, over extended periods and depending on factors like UV exposure, chemical contaminants in the hydraulic oil, and thermal cycling, accelerate aging of polymer components. Under typical hydraulic application conditions within the stated range, the AWO1 should retain clarity and resist discoloration. For critical continuous-duty installations at sustained +80°C, consider periodic inspection or consultation with the manufacturer for long-term aging data.
