Benefits of Sleev-it Penetration Seal

Traditionally, the process of maintaining the integrity of each penetration has been an arduous, time consuming and costly exercise. However, designed to be lightweight and easy to install, the SLEEV-IT marine penetration seals have the following benefits when compared to alternative processes and other market products: - 
  • The quantity of collars required: Only one SLEEV-IT marine penetration seal is needed for each penetration
    Benefits of Sleev-It fire penetration seals
    One seal either side of deck or bulkhead
  • Space or location flexibility: SLEEV-IT marine penetration seals can be fitted on either side of the deck or bulkhead (see diagram)
  • The weight and cost is significantly reduced: No further need for heavy and expensive steel combings
  • No extra insulation required
  • The levels of required welding / ‘hot works’ are significantly reduced: Most SLEEV-IT marine penetration seals can be ‘stitch’ welded as opposed to the need to be fully welded
  • Labour costs: A very quick and easy fitting process reduces significantly, the man hours needed to install a fire penetration seal
  • The flange fitting on the SLEEV-IT marine penetration seal covers the annular spaces and overlaps any poorly cut penetrations
  • When fitted on new builds, a fire stop system is in place as soon as the SLEEV-IT marine penetration seal is installed
  • A quick and easy retro-fit solution for when steel and plastic pipes are already in place
  • No sealant is required unless a gas tight seal is required
  • Installation flexibility: Most SLEEV-IT marine penetration seals can be either ‘stitch’ welded, bolted or screwed to the steel deck or bulkhead
  • Reduced maintenance: All SLEEV-IT marine penetration seals have a stainless steel casing or are powder coated to avoid the issue of rust
  • Various size collars are produced to fit the actual penetration being protected. Therefore, no wastage or purchasing of material that is NOT required


The benefits detailed above compare to other market solutions which ALSO require: -
  • Penetration seals to be fitted on both sides of the deck or bulkhead
  • Infill sleeves to be fitted and welded to the deck or bulkhead
  • Significantly more labour time to fit and install
  • Extra insulation fitted to the deck, bulkhead or combing in order to comply with IMO standards / regulations
  • Steel combings welded to the deck or bulkhead
  • Intumescent material to be applied around the pipes or cables and into the combings
  • Extra sealant which is time consuming, messy and costly
