Why choose this product

Engineered for Industrial Demands

This Boltigen oil sight glass is built with precision for critical equipment monitoring. Its stainless steel 304 body and borosilicate glass lens are chosen for durability and resistance to harsh fluids and pressures up to 800 PSI. Unlike generic indicators, it’s tested for reliable performance across a wide temperature range, ensuring clear visibility of oil condition and potential contaminants like water, crucial for preventing equipment failure.

Ideal for Indian Industrial Use

Perfect for air compressors, gearboxes, and hydraulic systems common in Indian manufacturing and workshops. Its robust build handles the varied operating conditions found across India. Skip if your equipment uses BSP threads or requires a sight glass rated for pressures significantly exceeding 800 PSI; consider a local supplier for specific thread compatibility if NPT is not standard on your machinery.

How to use

  • Prepare the Installation Port — Ensure the threaded port on your tank, compressor, or gearbox is clean and free of debris. Verify the port is 3/4" NPT male thread compatible. If your equipment uses a different thread standard like BSP, you will need an appropriate NPT to BSP adapter.
  • Apply Sealant and Install — Apply a suitable thread sealant (like PTFE tape or pipe dope) to the male threads of the sight glass. Carefully screw the sight glass into the port by hand, then tighten gently with a wrench on the hex head until snug and properly aligned for a clear view.
  • Check for Leaks and Monitor — After installation, operate the equipment and check the sight glass threads for any leaks. Once sealed, periodically observe the oil level and clarity through the tempered glass window to ensure proper lubrication and detect any water contamination.
