Product description
Roxtec sealing system with multidiameter technology: RS-series (steel division)
The RS cable penetration seal consist of two halves with removable layers making it adaptable to cables of different
diameters. It is available in different versions, RS, RS OMD, RS EMC or RS EX, depending on application.
The RS-seal is installed into a steel sleeve that is either welded, bolted, attached through expansion (SLFRS X),
attached with a nut (SLA) or by threads (SL 25/M24x1.5 and SL 31/M30x2) onto the steel division.
Application/Limitation
Approved for use as a single cable penetration system in class A-0 and A-60 steel bulkheads and decks for approved
ship cables. Other applications are subject to case-by-case approval.
Class A-15 and A-30 shall be insulated as A-60 and in addition the division is to be insulated at least 200 mm around
the penetration.
