How to Install the Duct Seal HG Sealing System
Installing the Duct Seal HG system is straightforward and efficient. Follow these steps for a secure and reliable seal:
- Abrade the first 20mm of the duct and cables: This helps to remove any grease, old sealant, and dust, ensuring a clean surface for sealing.
- Clean the duct and cables: All debris, grease, and dirt must be removed to allow the sealant to adhere properly.
- Insert the larger tubes/sleeves: Start with the larger set of tubes or sleeves, inserting them into the duct and between the cables. Ensure proper separation between the cables and the inner duct. For trefoil cables, join the larger tubes to create a cross shape, maintaining separation between the three single cables.
- Fill smaller gaps: Use singular large or small tubes/sleeves to fill any remaining gaps, creating a tight and strong support structure.
- Adjust tube depth if necessary: If the tubes or sleeves are pushed too far back, use long-nose pliers to pull them forward, ensuring they are positioned 20mm deep from the duct edge.
- Apply the GreyStuff or RedStuff sealant: Start applying the sealant around the cables, working from the bottom up to ensure thorough coverage.
- Finish with the provided Magic Sponge: Wet and squeeze the provided Magic Sponge, then dab the GreyStuff or RedStuff sealant to ensure it has securely grabbed the cables and duct, leaving a neat finish.
- Completion: Your installation is complete, providing a secure and durable seal.
- Done

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.
