Multi-path cable sealing module
The MCT rubber sealing module is the core component of the MCT penetration sealing system. Featuring a split-body design with concentric, peelable layers, it allows you to remove layers as needed to match cables and pipes of various diameters. When installed with a metal compression frame and secured with bolts, the module compresses and deforms to grip the lines tightly, ensuring an effective seal for the opening.
Core Advantages
One hole, multiple cables: save space
A single through-hole accommodates dozens of cables, replacing numerous traditional cable glands and significantly saving installation space.
Flexible adaptation, seamless scaling
Modular design allows installation or upgrades at any stage after cable laying. With reserved spare modules, adding new cables in the future requires no new holes.
Multi-layered protection for safety and reliability
Provides simultaneous protection against fire, water, air leakage, explosion, dust, and electromagnetic interference.
Easy to install, efficient to maintain
Installs with a simple square cutout; low site requirements. Modular design makes future maintenance and upgrades fast and easy.
Key Features
Split-body structure
Split-body design allows direct field installation over cables without removing cable glands.
Concentric peelable layers
Concentric peelable layers adapt to various cable outer diameters with broad size coverage.
Premium Specialty Rubber
High-grade specialty rubber; resistant to aging and vibration with waterproof, dustproof, and explosion-proof sealing.
Modular Snap-On
Modular design for flexible arrangement; use solid blind blocks to fill gaps.
Easy to retrofit later
Cables can be added or replaced later without new holes, making upgrades and maintenance simple.
Flame-retardant self-expanding
Flame rating UL94-V0; the module self-expands by approximately 15% in fire conditions to compensate for burned cable insulation.
