Four-Window Sight Glass (Fixed Type)

Four-Window Sight Glass (Fixed Type)
Core Differentiation:Made of copper base + chrome plating, distinct from conventional aluminum alloy models. It combines copper's *high-pressure resistance (≤0.5 MPa) & excellent thermal conductivity* with chrome plating's *strong corrosion resistance & long-lasting mirror finish*, available in 3/4" and 1" sizes for accurate medium observation in high-pressure, corrosive scenarios.

1. Material & Core Advantages
- Copper + Chrome Plating Composite Structure: Copper resists high pressure and ensures stable thermal conductivity (avoiding medium temperature interference); chrome plating enhances oil-gas corrosion/scratch resistance, maintaining mirror texture long-term with durable, clear windows.
- Fixed Non-Rotating Structure: Four high-borosilicate glass windows enable 360° dead-angle-free observation, directly viewing medium flow rate and cleanliness for more stable structure.

2. Key Specifications
- Sizes: 3/4", 1" (compatible with NPT/BSPT/G threads).
- Working Pressure: ≤0.5 MPa.
- Temperature Range: -15℃ ~ +80℃.

3. Applications & Usage
- Applicable Scenarios:
① High-pressure hydraulic systems (≤0.5 MPa): Observe hydraulic oil to check pump/valve/pipeline blockage/leakage;
② Chemical/weakly corrosive pipelines: Chrome plating resists chemical corrosion for monitoring oil/weakly corrosive medium flow;
③ High-end equipment (machine tools, precision hydraulic stations): Chrome-plated mirror finish for aesthetic and durability.
-Usage Steps:
1. Select Size: Choose 3/4" or 1" matching pipeline interface & thread;
2. Sealed Installation: Wrap threaded end with oil-resistant tape, screw clockwise into pipeline (tighten moderately to avoid copper thread slipping);
3. Observation & Judgment: During operation, observe medium via four windows — uniform flow & no impurities → normal system; disordered flow/foreign matter → inspect pipeline/filter.
