Duct Seal HG (Water & Gas) Duct Sealing System for Large Cables and Pipes - ≤2 Bar Pressure Resistance

The Duct Seal HG system is a re-enterable duct sealing solution specifically designed for large, heavy cables and pipes in complex duct scenarios. It effectively prevents the ingress of harmful or flammable gases, liquids, smoke, and vermin, keeping installations safe and secure. Whether used in data centres, substations, or waste-to-energy plants, Duct Seal HG has got you covered.

Duct Seal HG Features

  • Patent Pending Trefoil/Triplex Cable Separation: Our tubular rubber backing system can be configured in continuous strips, rings, or cross shapes, providing optimal support and separation for large cables or pipes. This unique design, suitable for trefoil cables and raceway seals, simplifies installation and meets DSEAR compliance.

  • MEKO-Free, Fybrid, Non-Hazardous Intumescent Sealant: Duct Seal HG uses our advanced Grey Stuff and Red Stuff sealants. These flexible, zero-halogen, MEKO-free sealants ensure safety for installers and the environment alike.

  • Water & Gas Tight: The Duct Seal HG system provides a solid barrier against water and gas, making it perfect for critical infrastructure applications.

  • Toxic Gases Resistant: Specifically designed for the water industry, Duct Seal HG resists gases like methane, chlorine, and hydrogen sulphide.

  • Hydrocarbons Resistant: Designed for petrol forecourt applications, Duct Seal HG withstands exposure to hydrocarbons, making it ideal for installations in areas with chemical agents.

  • Flame Retardant: Duct Seal HG has been tested to UL94:2013 ANSI / UL 94:2018 standards for flame retardancy.

  • Industry Compliant: Duct Seal HG meets standards including DSEAR, WIMES, DCG, APEA, the Blue Book, and ATEX, ensuring suitability for a range of demanding sectors.

  • Microbial Defence: Built-in resistance against fungi and bacteria ensures long-lasting protection in tough environments.

  • Low Cable De-Rating: With a 20mm thickness, the thermal resistance is only 5.1 K/W, ensuring the cable maintains its maximum current capacity.

  • MADE IN UK: All Duct Seal HG components are proudly designed and manufactured in the UK, ensuring quality and craftsmanship.

Duct Seal HG Applications

  • Data Centres: Provides a reliable seal around large cables in critical data infrastructure, protecting against external environmental threats.

  • Substations: Effectively seals ducts in electrical substations, blocking harmful substances from entering.

  • Pumping Stations: A solution for the water industry where toxic gas resistance and a secure, water-tight seal are essential.

  • Waste-to-Energy Plants: Built for harsh environmental conditions, ensuring long-term duct integrity in waste-to-energy facilities.

  • Wind Farms/Turbines: Offers robust protection for renewable energy installations that operate in exposed environments.

  • Electrical Utilities: Ensures safe and secure duct sealing for various electrical utility applications.

  • Rail Industry: Meets Network Rail standards, making it ideal for rail infrastructure projects.

Why Choose Duct Seal HG for Duct Sealing?

Duct Seal HG isn’t just another duct sealing system—it’s a patented solution that meets the highest industry standards. With features like trefoil/triplex cable separation and advanced intumescent sealants, Duct Seal HG offers:

  • Unbeatable Flexibility and Protection: The re-enterable design allows easy maintenance and adjustments. Its unique backing system supports large cables, making it suitable for complex cable scenarios.

  • Compliance and Safety: Meeting DSEAR, WIMES, and other industry standards, Duct Seal HG ensures installations are safe and compliant with regulations.

  • Environmentally Safe and Non-Hazardous: FyBrid technology ensures the Grey Stuff and Red Stuff sealants are non-hazardous and environmentally friendly, providing peace of mind for installers and end-users.

How to Install the Duct Seal HG System

  1. Abrade the First 20mm: Lightly abrade the initial 20mm of the duct and cables to remove grease, old sealant, and dust, creating a clean surface for the sealing compound.

  2. Clean the Duct and Cables: Remove all debris, grease, and dirt to ensure the Grey Stuff or Red Stuff sealant bonds well.

  3. Insert Larger Tubes/Sleeves: Begin with the larger tubes or sleeves, inserting them into the duct to separate the cables from the inner duct wall. For trefoil cables, join the larger tubes to create a cross shape to maintain separation among the cables.

  4. Fill Smaller Gaps: Use additional tubes to fill any remaining gaps, forming a solid support structure.

  5. Adjust Tube Depth: If the tubes are too deep, use long-nose pliers to position them approximately 20mm from the duct edge.

  6. Apply the Grey Stuff or Red Stuff Sealant: Begin at the bottom and work upwards for complete coverage.

  7. Finish with the Magic Sponge: Wet and squeeze the Magic Sponge, then dab it over the sealant to ensure it adheres to both the cables and duct, leaving a clean finish.

  8. Complete: Your installation is now secure and sealed.

Installation

One Kit per Box

All components are included to seal 1 x duct as per the kit size mentioned (A caulking gun is not included but can be sold separately). ** One kit may fill more than one duct, depending on the cable % filled. Call 0161 806 1666 for advice**


Cable Separation

It's imperative to ensure separation between each cable and from the inside of the duct. Our unique daisy-chained circular tubes easily separate and support single or multiple cables.

Using our patent-pending tubular rubber tubes, various shapes can be made to help with cable separation, such as trefoil/triplex cables.


Running Water

For best results, the duct and cables should be dry with no running water. All dirt, oil, or grease must be cleaned before applying GreyStuff. If you have running water, please contact AC Cable Solutions for advice on 0161 806 1666. We recommend using a Kraso Mechanical seal  —click here for further information. 

Cure Time

Grey Stuff and Red Stuff will cure 3-4mm daily, depending on Humidity and temperature. The higher the humidity percentage and temperature, the quicker GreyStuff will cure. For an effective seal, a minimum of 20mm of Grey Stuff or Red Stuff is required.

Cleaning

Uncured material spillages can be cleaned with a solvent-based wipe.


Health & Safety

Grey Stuff and Red Stuff are based on a hazard-free neutral curing system to protect users when carrying out tasks like sealing cable ducts. Non-hazardous Zero MEKO.

Compliance 

Duct Seal HG complies with WIMES, APEA, ATEX & DSEAR, SEWAGE FOR ADOPTION, and the DCG guidance.

Re-entry & Removal

Grey Stuff and Red Stuff will cure a similar hardness to a rubber eraser, so re-entry and removal are achievable. The ease of this depends on the type of tools used. For example, a sharper tool will be easier than a blunt-ended tool. Only use sharp tools when cables are de-energized. AC Cable Solutions accepts no responsibility for damaged cables.

Cable Suitability

Grey Stuff and Red Stuff is a single-component neutral curing system containing no solvents. Our formulation does not damage the properties of a cable sheath or stain surfaces.


Storage

Grey Stuff and Red Stuff should be kept in a cool, dry environment and away from sunlight. The product shelf life is 12 months. Once opened, any remaining product can be used for one month, provided the screwcap is securely fitted.
