MCT - Round Transit | RGP - SFRBO
On land At sea Duct Seal

Used in high-risk maritime, offshore and land-based environments to minimize danger by preventing the spread of fire, water, gas, chemicals and other hazardous substances.

RGP - SFRBO

For bolting when cables are already in place

The RGP assembled in an open version sleeve for installation in holes where cables have already been pulled. The sleeve has predrilled holes which enables bolting where welding is prohibited or stress levels making it unsafe. 

It is supplied as a kit, complete with drilled holes, bolts, nuts, washers and a gasket or sealing compound.

Correct and safe installations

To achieve the highest standard of safety, a cable or pipe transit must be installed correctly. As there are many different types of frame – which may be either welded, bolted or glued into position – and insert block, it is essential that installers known when to use the most appropriate installation method.

For more information, please view following instructions, videos or download manuals as PDFs.

 


PRESSURE-TIGHT INSTALLATION
All contact surfaces between the pipe and the RGP plug must be cleaned carefully prior to installation. Do not use any lubricant on these surfaces. All blocks must be lubricated carefully with MCT Brattberg lubricant. The penetration must not be subjected to pressure for at least 48 hours after installation. This is to allow the pressure to equalise throughout the penetration. It will take more time for the pressure to equalise at temperatures below 20°C.


Note: If the installation is subjected to pressure, all components must be replaced after removal and refitting.


 

How to install a MCT Brattberg RGP/RGPO, horizontal

Use bolts for this transit

This transit was designed for areas where welding is prohibited or welding induced stress levels making welding unacceptable. This transit is therefore to be fastened by bolts to ensure installation quality.

The round transit system consists of a round rubber frame and rubber blocks. The RGP circular multi cable & pipe transit is assembled in sleeves, pipes, drilled or cast holes and packed with rubber blocks suited for each cable and pipe dimension. The compression bolts are tightened to compress the rubber blocks against cables and pipes to establish a tight seal.

RGP has an open side intended for installation in holes where cables have already been pulled.
