1. Product Overview
The ROXTEC EXRM00100401000 is an ATEX/IECEx certified RM Ex cable sealing module built with Roxtec’s patented Multidiameter™ technology, purpose-engineered to create a fully flameproof, ingress-resistant seal for single cables or pipes passing through walls, bulkheads and equipment enclosures in explosive hazardous locations. As part of the Roxtec RM Ex series, this model is factory-calibrated for 21.5–34.5 mm outer diameter cables and pipes, with compact 40×40×60 mm dimensions and a total weight of just 0.14 kg. It eliminates the need for custom-sized sealing gaskets, and works seamlessly with matching Roxtec frames and accessories to form a complete, certified cable transit sealing solution for oil & gas, mining, chemical processing and other high-risk industrial sites.

3. Key Features & Advantages
This Roxtec Ex sealing module delivers three core advantages that generic cable glands cannot match for hazardous area deployments. First, the patented Multidiameter™ peelable layer design lets on-site technicians adjust the inner diameter of the module by peeling off pre-engineered rubber layers, so a single part number can fit all cables in the 21.5–34.5 mm range, drastically reducing spare part SKU counts and eliminating the risk of mismatched sealing sizes on site. Second, the full Ex certification ensures the module meets strict flameproof, dust and water ingress protection standards for explosive environments, preventing flammable gas or flame propagation across the transit point to avoid secondary explosion risks. Third, the compact 60 mm depth design makes it extremely easy to install even in narrow wall gaps or limited enclosure space, no special tools required for full installation in under 5 minutes per module.
4. Applications & Real-World Value
The EXRM00100401000 is widely deployed in safety-critical cable transit scenarios across high-risk industries, delivering tangible operational and safety value for end users. For offshore oil and gas platforms and onshore refineries, it seals power and signal cables passing through hazardous zone 1/zone 2 wall and deck penetrations, preventing explosive gas from spreading between different functional areas and meeting strict global safety regulatory requirements. For underground mining operations, its robust ingress protection blocks dust and water from entering electrical control rooms through cable penetrations, extending the service life of internal electrical equipment. For chemical processing plants, the module’s flexible design allows teams to add or replace cables without re-welding or re-sealing the penetration opening, cutting the time required for process automation upgrade projects by more than 70% compared to traditional fixed sealing solutions. For maintenance teams, the unified part number system drastically simplifies spare part inventory management, eliminating the risk of project delays caused by missing custom-sized sealing components.
