FOUR-WINDOW SIGHT GLASS COUPLING

MATERIAL

• Body: Aluminum, Oxidation treatment
• Seals: NBR

• 360° panoramic visualization enables full-view observation of internal oil supply dynamics. It can clearly check oil circuit on-off and flow velocity at any installation angle, accurately troubleshooting oil cutoff, pipeline blockage                                    and oil supply fluctuation faults.
• Realize multi-angle real-time monitoring of air bubbles, moisture, impurities and emulsification turbidity in oil liquid, effectively eliminating hidden dangers such as vapor lock, oil deterioration and pipeline air intake.
• The four-sided transparent structure facilitates daily inspection and after-sales maintenance. The oil circuit operating condition can be quickly judged without adjusting the pipeline angle, greatly improving maintenance                                                  efficiency.
