Single-Window Sight Glass
Single-Window Sight Glass
Core Differentiation：Dual materials (iron/stainless steel) + multiple specs (3/4"×25, 1"×25, 3/4"×22) available, flexibly matching "cost-priority" or "corrosion-resistant" scenarios, distinct from conventional single-material/single-spec products.
1. Materials & Core Advantages
- **Iron**：High cost-performance, rust-proof treated for ordinary hydraulic/general lubrication scenarios *without strong corrosion*.
- **Stainless Steel**：Strong corrosion resistance for chemical, food-grade, coastal scenarios *with high corrosion/hygiene requirements*; higher strength, no deformation after long-term use, more reliable sealing.
2. Key Specifications
- Sizes：3/4"×25, 1"×25, 3/4"×22 (compatible with NPT/BSPT/G threads).
- Working Pressure：Iron ≤0.3 MPa；Stainless Steel ≤0.5 MPa.
- Temperature Range：Iron -10℃~+60℃；Stainless Steel -15℃~+80℃.
- Window：High borosilicate wear-resistant glass, compact single-window with clear view, impact/scratch-resistant.
3. Applications & Usage
- Iron Scenarios & Operation：Ordinary hydraulic/general lubrication pipelines (cost-sensitive, no strong corrosion) → Select matching spec, wrap thread with oil-resistant tape, screw into interface (tighten moderately), observe medium flow rate/cleanliness to judge system status.
- Stainless Steel Scenarios & Operation：Chemical/food-grade/coastal pipelines (high corrosion/hygiene) → Select matching spec, wrap thread with oil-resistant tape, screw into interface (avoid scratching threads), observe medium flow rate/cleanliness to judge system status.
