DuctSeal HG Cable Duct Sealing System (large heavy cables) - ≤2 Bar Pressure Resistance
DuctSeal HG (Water & Gas) is a NEW re-enterable duct sealing system that is extremely flexible in its ability to seal large, heavy cables & pipes in ducted networks to protect and stop the ingress of harmful or flammable gases, liquids, smoke, and vermin.
DuctSeal HG comes complete with our PATENT PENDING unique tubular rubber backing system that can be joined together in a long continuous strip, joined to make a ring/collar, but best of all, joined in a cross shape to create a perfect shape for separating trefoil/triplex cables. This unique design ensures DSEAR compliance but also aids the installer as it’s simple & quick to create the support & separation on large cables or pipes. The PATENT PENDING ULTIMATE backing system, which is one of a kind, is combined with our NEW Fybrid flexible intumescent, zero halogen, & zero Meko adhesive and sealing compound, GreyStuff. All are designed and manufactured in the UK.
DuctSeal HG, along with Grey Stuff, is a non-hazardous, FyBrid superior single-component, neutral curing sealant that has been specifically developed to cope with the harsh environments around duct openings to ensure ducted networks and penetrations are protected.

One Kit per Box
All components included to seal 1 x duct as per the kit size mentioned (Caulking gun not included, but can be sold separately). ** One kit may fill more than one duct, depending on cable % fill. Call 0161 806 1666 for advice**
It’s imperative to ensure separation between each cable and from the inside of the duct. Our unique daisy-chained circular tubes easily separates and supports single or multiple cables.
Using our patent pending tubular rubber tubes, various shapes can be made to help with cable separation, for example, trefoil/triplex cables.
The duct & cables should be dry for best results 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. Most of the time, we recommend using a Kraso Mechanical seal - Click here for further information.
GreyStuff will cure 3-4mm daily, depending on the Humidity and temperature. The higher the humidity %, and temperature, the quicker GreyStuff will cure. A minimum requirement of 20mm GreyStuff is required for an effective seal.
Uncured material spillages can be cleaned with a solvent-based wipe.
Health & Safety
GreyStuff is based on a neutral curing system that is hazardous-free to protect users when carrying out tasks like sealing cable ducts. Non-hazardous Zero MEKO.
DuctSeal LG complies with WIMES, APEA, ATEX & DSEAR, SEWAGE FOR ADOPTION & THE DCG GUIDANCE.
Re-entry & Removal
GreyStuff will cure to a similar hardness of 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.
GreyStuff is a single-component neutral curing system containing no solvents. Our formulation does not damage the properties of a cable sheath or stain surfaces.
GreyStuff should be kept in a cool, dry environment and away from sunlight. Product shelf life is 12 months. Once opened, any remaining product can still be used for 1 month afterwards, provided the screwcap is securely fitted.
