Four-Window Sight Glass (Multi-Spec Compatible)
Four-Window Sight Glass (Multi-Spec Compatible)
Core Differentiation:Made of **copper base + chrome plating**, available in **4 specs: 3/4"×3/4", 1"×1", 3/4"×1", 1"×3/4"**, distinct from conventional "single-spec" sight glasses. It leverages copper's high-pressure resistance (≤0.5 MPa) & stable thermal conductivity, while chrome plating enables strong corrosion resistance & long-lasting mirror finish, precisely matching observation needs of different pipeline interfaces.
1. Materials & Core Advantages
- Copper + Chrome Plating Composite Structure: Copper base resists high pressure and offers excellent thermal conductivity (avoiding medium temperature interference); chrome plating significantly enhances oil-gas corrosion/scratch resistance, maintaining mirror texture long-term, with wear-resistant, clear high-borosilicate glass windows.
- Multi-Spec Full Coverage: Four specs cover "same-diameter/heterogeneous-diameter" pipeline interface scenarios, meeting observation needs of multiple sections and devices with one product series, reducing selection and inventory costs.
2. Key Specifications
- Sizes: 3/4"×3/4", 1"×1", 3/4"×1", 1"×3/4" (compatible with NPT/BSPT/G threads).
- Working Pressure: ≤0.5 MPa.
- Temperature Range: -15℃ ~ +80℃.
3. Applications & Usage
- Applicable Scenarios (More Flexible Than Single-Spec Sight Glasses):
① Multi-spec pipeline systems: Both same-diameter (3/4"×3/4", 1"×1") and heterogeneous-diameter (3/4"×1", 1"×3/4") pipelines can be matched, covering observation of hydraulic, lubrication, fuel and other systems.
② Equipment upgrade & renovation: When old pipeline interfaces have diverse specs, the four-spec series can be directly adapted without additional adapters.
③ High-pressure complex working conditions: Observe oil under ≤0.5 MPa; copper + chrome plating resist high pressure/corrosion, and multiple specs meet different equipment interface needs.
- Usage Steps:
1. Select Size: Choose the corresponding spec (same-diameter/heterogeneous-diameter) according to the "two-end interface sizes" of the pipeline.
2. Sealed Installation: Wrap both threaded ends of the sight glass with oil-resistant tape, screw into pipeline interfaces (tighten copper parts moderately to avoid thread slipping; chrome plating prevents seizing).
3. Observation & Judgment: During operation, observe medium via four windows — uniform flow & no impurities → normal system; abnormal flow/foreign matter → inspect pipelines/filters.
