Customised Mechanical Transits: The Ultimate Solution for Cable and Pipe Sealing

Customised Mechanical Transits: The Ultimate Solution for Cable and Pipe Sealing

Do You Need a Customised Duct Seal?

When it comes to sealing cables and pipes, one size doesn't fit all. Off-the-shelf solutions often lead to time-consuming adjustments, inadequate sealing, and unnecessary costs. Whether you refer to them as Customised Mechanical Transits, Customised Mechanical Duct Seals, or Customised Mechanical Circular Transits, finding the perfect fit for your specific needs is crucial.

At AC Cable Solutions, in partnership with Kraso GmbH of Germany, we specialise in providing customised mechanical duct seals tailored to your exact specifications. With the unique ability to customise and manufacture duct seals within 24 hours and ship them anywhere in the world within 10 days, we offer an unparalleled service that saves you time, effort, and money.


Why Choose Customised Mechanical Transits?

Traditional sealing methods like compounds, mechanicals seals with peelable layers, such as ourselves, Roxtec, & MCT or standardised products can be inefficient and imprecise. They often require on-site adjustments, leading to delays and increased labour costs.

Customised mechanical cable transits eliminate these issues by providing:

  • A Perfect Fit: Designed to match your exact duct and cable or pipe configuration.
  • Time Efficiency: No need to adjust or modify seals on-site.
  • Cost Savings: Reduce labour costs and avoid wastage from ill-fitting seals.
  • High Performance: Ensure optimal sealing against water, gas, and pests.

What Is a Customised Seal?

A customised seal is your answer to consistent, high-quality, perfectly fitting duct sealing systems—also known as Transit Seals or Multi-Cable Transits

All we need to know is:

  • Penetration Size: The diameter of the duct or borehole.
  • Type of Penetration: Whether it's concrete or cast-in-place ducts.
  • Cables or Pipes: The type and size of the cables or pipes that need sealing.

That's it! We'll handle the hard work and manufacture duct seals that suit your exact requirements.


Introducing the Kraso Type SD System

Kraso – Customisable Split Mechanical Duct Sealing System – Type SD 2

Most of our customised duct seals or cable transits utilise the Kraso Type SD system.

Key Features:

  • Fully Customisable: Accommodates duct sizes from 50mm up to 500mm, with customised holes for your specific number and size of cables.
  • High Pressure Resistance: Withstands up to 5.0 Bar pressure (equivalent to 50 metres of water).
  • Patented Torque Nut: No torque wrench required—ensures precise tightness, eliminating under or over-tightening.
  • Durable Construction: Made from high-quality, non-corrosive stainless steel V2A for longevity and reliability.
  • Easy Installation: Comprises two components, allowing for convenient installation even in damp conditions or areas with ongoing water flow.
  • Gas and Pest Resistant: Protects against toxic gases like Radon, Hydrogen Sulfide, Methane, Chlorine gas, and prevents rodent intrusion.

Engineered to thrive in the most challenging environments, the Kraso Type SD seal rises above the rest by conquering intense water and gas pressures while repelling hazardous elements.


Specialist Solutions: Kraso Type DD/GR and VD/GR

Kraso – Ribbed Ducting Sealing System – Type GR 1

For situations involving weaker ribbed ducts, softer cables like unarmoured fibre optic cables, or pre-insulated district heating pipes (such as LOGSTORE or CPV), we recommend the Kraso Type DD/GR or VD/GR.

Features of Kraso Type GR:

  • Gentle on Insulation: Special rubber composition prevents damage to your insulation.
  • Enhanced Pressure Distribution: Central plates distribute pressure evenly, reducing the risk of damage to pipework.
  • Foolproof Torque Control: Patented torque nut ensures the correct torque is applied, eliminating over-tightening or under-tightening.
  • Flexibility: Accommodates up to 8 degrees of deviation and axial movement, ensuring long-lasting performance.
  • High Pressure Resistance: Withstands pressures up to 2 Bar.

This sealing system comprises a complete, un-welded plate and must be installed before the ribbed duct, offering a robust seal ideal for high-pressure environments.


Why Use Customised Mechanical Duct Sealing Systems?

  • No Peeling Back Layers: Saves time and money by eliminating the need to adjust seals on-site.
  • Precise Fit: Manufactured to your exact specifications for optimal sealing.
  • Versatility: Ideal for multiple-sized cables or pipes where off-the-shelf solutions aren't available.
  • Any Size Capability: We regularly manufacture seals up to 1000mm in diameter.
  • Effective in Running Water: Suitable for ducts with running water—mechanical seals outperform putty or sealants.
  • High Pressure and Gas Resistance: Capable of sealing up to 10 Bar of pressure (100 metres of water).
  • Stock Availability: For common-sized cables and ducts, we can manufacture customised seals and hold stock for immediate dispatch.
