Description

The 1622365900 Sight Glass is an essential visual monitoring component installed on Atlas Copco screw-type air compressor oil chambers. Designed to provide continuous, distortion-free visibility of lubricant levels, this sight glass uses a high-transparency optical lens combined with a robust sealing seat, ensuring accurate readings even during rapid pressure fluctuations inside the lubrication system.

Compared with ordinary sight glasses, this model is engineered with enhanced optical clarity, thicker impact-resistant lens construction, and stronger retention against mechanical vibration—making it suitable for compressors operating in harsh industrial environments.

Key Features & Performance Advantages

High-Transparency Optical Viewing Lens

The sight glass uses an upgraded optical-grade polymer or tempered-glass material, allowing operators to easily observe:

  • Real-time oil level
  • Oil color and contamination
  • Presence of foaming or aeration
  • Clarity changes caused by oxidation

The lens maintains transparency even after long exposure to hot oil and additive-rich synthetic lubricants.

Reinforced Body with Impact-Resistant Construction

1622365900 is built with thicker wall sections around the lens body to resist:

  • Vibrations transmitted from the compressor block
  • Accidental impacts during maintenance
  • Pressure pulses during load/unload cycles

This reinforced design minimizes cracking, warping, and lens loosening—common issues in low-quality sight glasses.

Tight, Oil-Proof Sealing Interface

The sealing geometry uses a deep-seat gasket channel that ensures:

  • Uniform compression across the sealing ring
  • Reduced micro-leakage in high-temperature operation
  • Long-term seal integrity without gasket hardening
  • Compatibility with synthetic PAO, ester, and mineral-based oils

This structure prevents seepage around the lens perimeter, even after extended thermal cycling.

Compact Structure

Unlike modular gauges, this sight glass uses a compact, integrated circular design that requires minimal installation space.
This makes it especially suitable for:

  • Compact Atlas Copco compressor models
  • Units with limited front-panel clearance
  • Machines where technicians require clear visibility from multiple angles
  • The flush-mount design also prevents accidental snagging during maintenance.

Application Scenarios

This sight glass is suitable for:

  • Atlas Copco screw-type air compressors
  • Oil-injected models requiring continuous visual oil inspection
  • Industrial facilities with long runtime cycles
  • Systems where lubricant degradation needs to be monitored closely

Its optical-grade design makes it ideal for compressors operated in environments with strict lubrication management requirements.

Installation & Service Notes

  • Install on a clean, debris-free mounting port to ensure proper sealing.
  • Avoid overtightening during installation to protect the lens perimeter.
  • Periodically clean the exterior surface with a soft cloth to maintain crystal visibility.
  • Replace the sight glass immediately if cracks, cloudiness, or gasket aging appear.
  • Routine visual inspection enhances lubricant reliability and protects compressor bearings.

Why Choose the 109265601 / 109265600 Oil Level Gauge?

Because it provides:

  • Higher optical clarity
  • Stronger structural safety
  • Better sealing reliability
  • Longer resistance to oil, heat, and vibration

This sight glass is engineered specifically to meet the operational demands of Atlas Copco screw compressors, ensuring consistent, worry-free oil monitoring.
