TST SEAL Peelable Sealing Modules, with their advantages of flexible adaptation, rapid installation, and support for future expansion, have rapidly penetrated from the traditional marine industry into many demanding sectors, becoming the “smart standard component” of modern through-wall sealing systems. The following are typical applications and value demonstrations of TST SEAL Peelable Sealing Modules in core industries:
- Marine and Offshore Equipment: The “Sealing Cornerstone” of the Marine Environment
Application Scenarios:
Cable routing through ship bulkheads/decks (power, communication, radar)
Sealing of monitoring cables in LNG carrier cargo holds
Inlet ports for control cabinets on offshore drilling platforms
Core Requirements:
A-60 fire resistance, IP68 watertightness, salt spray corrosion resistance, vibration resistance
Typical Value:
TST SEAL Peelable Sealing Modules feature a peelable design to accommodate cables of different outer diameters (e.g., Φ20–80mm), avoiding custom-made openings;
Subsequent sensor installation can be performed without cutting bulkheads, meeting the upgrade needs of warships/merchant ships;
The 316L stainless steel frame + EPDM rubber is certified by classification societies such as DNV and CCS.
✅ TST SEAL Case Study: After adopting TST SEAL strippable modules, a domestically built destroyer improved cable installation efficiency by 60% and passed the Navy’s GJB 150A vibration test.
- Offshore Wind Power: The “Maintenance-Free Guardian” in High Humidity and High Salt Environments
Application Scenarios:
Wind turbine tower foundation cable penetration (power + fiber optic composite cable)
Offshore substation control room cable entry
Electrical compartment sealing on maintenance vessels
Core Requirements: Long lifespan (25+ years), protection against lightning strikes and electromagnetic interference, support for remote monitoring and cable expansion
Typical Value:
Single module compatible with multi-core composite cables, simplifying wiring structure; Tool-free expansion capability, supporting future addition of temperature/strain fiber optics; Low-smoke halogen-free materials comply with IEC 61400-25 wind power safety standards.
✅ TST SEAL Case Study: The CGN South China Sea project used TST SEAL strippable sealed modules, achieving zero leakage for 3 years and reducing maintenance costs by 40%.
- Rail Transit: “Efficient Solutions” for Confined Spaces
Application Scenarios:
Metro/High-Speed Rail Car Body Cable Tray Entry
Signal Control Cabinet Inlet

Summary: Why are various industries shifting towards TST SEAL peelable modules?
Traditional fixed-hole modules: | TST SEAL Peelable Sealing Module |
One hole, one wire; cannot be modified | Multiple diameters in one mold, flexible adaptation |
Expansion requires structural damage | Single-sided expansion, no power interruption |
Numerous inventory models | Standardized, fewer SKUs |
Installation relies on precise drilling | ±5mm tolerance self-compensation |
Production cycle of 15-30 days | In-stock, 24-hour shipping |
Standard hole diameter and dimensions | Supports standard and non-standard customization, can replace Roxtec |
Incomplete certifications | Full range of products |
Today, the TST SEAL peelable sealing module is not just a “sealing component,” but a flexible, variable-diameter, digitally-enabled, modular, and sustainably maintained infrastructure. With increasing global demands for safety, efficiency, and green manufacturing, it is transforming from an “optional” to a “must-have” for various industries.
