application
- Wall-mounted pipe end sealing: Concealed sealing of wall-penetrating pipe ends maintains a smooth and aesthetically pleasing wall surface.
- Equipment integrated pipe protection: Sealing of internal pipe ends in mechanical equipment prevents foreign object intrusion.
- Fire protection system embedded interfaces: Sealing of reserved ports in fire protection networks that are flush with the wall surface.
- Ship deck pipe management: Sealing of deck pipe ends achieves anti-trip safety design.
- Industrial equipment test interfaces: Sealing embedded testing ports after pressure testing.
- Underground pipeline maintenance protection: Sealing underground pipeline ends to prevent silt buildup.
- Laboratory bench pipeline: Sealing gas/water interfaces on laboratory benches to maintain a smooth surface.
- Decorative pipeline end treatment: Sealing decorative metal railings/furniture pipeline ends.
advantages
- Countersunk flush seal: The embedded design ensures that the pipe opening is completely flush with the contact surface.
- Square hole quick operation: The square drive hole is compatible with standard tools for quick installation.
- High-pressure dynamic seal: Maintains long-term zero leakage stability under extreme conditions.
- Full-environment corrosion resistance: Thickened galvanized coating resists moisture and chemical corrosion.
- Impact-resistant reinforced structure: Countersunk design enhances resistance to external impact forces.
- Wide size coverage capability: Compatible with micro to large-scale industrial pipeline systems.
- Temperature extremes adaptability: Maintains seal integrity in harsh cold and high-temperature environments.
- Lifetime maintenance-free guarantee: Specialized manufacturing processes significantly extend protective lifespan.
packing
- Countersunk Face-Specific Protective Pad: Custom PE soft pad conforms to the countersunk curved surface to prevent scratches.
- Square Hole Dust-Proof Sealing Cover: Dedicated screw cap protects the square drive hole structure.
- Threaded End Dual Protection: Screw cap + foam ring composite protection seals the threads.
- Individual Shock-Resistant Envelopment: Bubble column bag completely wraps the tube plug surface.
- Smart Size-Specific Positioning: Honeycomb cardboard compartments categorize and secure items by size.
- Visual Identification System: Transparent windows on the outer box clearly display product specifications.
- Full-Process Traceability Management: Laser engraving + smart QR codes provide dual traceability.
