Roxtec supplier in Romania
Modular sealing systems for cable and pipe penetrations
Founded in 1990 · Headquarters: Karlskrona, Sweden
Who is Roxtec and what does it make?
Roxtec is a Swedish manufacturer of modular sealing systems for cables and pipes, founded in 1990 and based in Karlskrona. The company's Multidiameter technology uses rubber modules with removable layers that adapt to the exact diameter of the cable or pipe fitted, regardless of diameter variations in the project. From the Roxtec range we can quote sealing systems for penetrations through walls, floors and panels, with protection against fire, gas and water.
The difference compared with a classic seal made of foam or sealant is that Roxtec modules remain removable: a new cable can be added or replaced without redoing the whole seal, while keeping the fire or water protection class. MCT (Multi-Cable Transit) systems cover penetrations with dozens of cables through the same frame, sized with the help of the manufacturer's own software, Transit Designer. The category of modular sealing systems for infrastructure places Roxtec alongside other suppliers specialising in cable penetrations for industrial or marine environments.
For projects in Romania with fire compartmentation or water tightness requirements (industrial halls, pumping stations, ships or platforms), Roxtec makes sense where cable penetrations through walls or floors must keep the protection class of the compartment, not merely be dust-tight.
What do we supply from the Roxtec range?
| Product | Description |
|---|---|
| Multidiameter System | Rubber modules made of concentric removable layers, which are peeled by hand down to the exact diameter of the cable or pipe fitted, without needing a dedicated module for each individual diameter. The modules are fitted in a Roxtec frame that provides sealing and, where applicable, fire protection. They reduce the number of part types held for a project with varied cable diameters. The customer specifies the number and diameters of the cables or pipes passing through each frame. |
| MCT – Multi-Cable Transit | Sealing frames for penetrations with a large number of cables through walls or floors, used for the entry of electrical and communication cables into a building, ship or industrial platform. Sizing is done with the Transit Designer software, which simplifies product selection and the design of penetrations. Typical application: the cable room of an electrical substation or the engine room of a ship. The customer sends the list of cables and the planned penetration points. |
| Sealing Solutions for Electrical Panels | Sealing systems dedicated to cable entries into electrical panels and automation cabinets, which keep the IP protection rating of the enclosure even after new cables are added. Useful for panels exposed to dust, humidity or water jet washing. The customer specifies the panel type, the protection rating required and the number of cables to be passed through. |
Why Roxtec?

How do we supply Roxtec in Romania?
For Roxtec we state plainly what we confirm: the technical information above comes from the technical documentation of the Swedish manufacturer. Sealing frames and modules are sourced to order through EU supply channels, usually in 1–4 weeks from order confirmation. For a quotation we need the number and diameters of the cables or pipes, the type of wall or floor penetrated and the protection class required (fire, water, gas). We cannot promise permanent availability from stock for all module sizes.
Sizing of penetrations is done by the customer or designer in the free Roxtec Transit Designer web application.
Frequently asked questions about Roxtec
How do I choose the right Roxtec module for my cable diameter?
The choice is made by the real outside diameter of the cable or pipe, not by its commercial designation: each RM code covers a precise range, for example RM 40 for 21.5-34.5 mm or RM 60 for 28-54 mm. The module can be adjusted by removing the inner layers, so one base code can cover several close diameters from the same family.
What does the WOC variant mean for Roxtec modules?
WOC is a variant of the Roxtec RM modules; the exact meaning of the abbreviation and the fitting method are confirmed from the Roxtec documentation for the module chosen. The codes RM 60 WOC, RM 80 WOC and RM 120 WOC cover large diameters, from 28 to 99 mm.
Do you supply Roxtec modules in Romania?
Yes, we source the Roxtec series to order, usually in 1–4 weeks, because we do not keep this range on the shelf. For a correct quotation we need the exact outside diameter of the cable or pipe, the type of wall or frame used and the number of entries required, so that we confirm the right RM code before ordering.
What is the difference between RM 40 and RM 40 10-32?
The difference lies in the diameter range covered: standard RM 40 is designed for 21.5-34.5 mm, while RM 40 10-32 extends the useful range towards smaller values, down to 9.5 mm, making it more flexible when the cable diameter is not known precisely at the time of ordering. Both modules belong to the same Multidiameter system and are fitted in the same Roxtec frames.
How do I request a Roxtec quotation?
