Sealing grommets for pipes Ø 120 - 170 mm (4.75”-6.75“)

 

Advantages

  • Secure bond, quick and secure sealing, indoors or out
  • High-quality EPDM, extremely flexible and elastic, no excess bushing
  • Waterproof, also suitable for penetrations in façades and roof linings
  • Pipes can be still be pulled or pushed
  • Lowest VOC rating in hazardous substance test
 

Application

Sealing grommet made of strong and highly flexible EPDM. Ideally suited for rapid and permanent airtight feedthroughs for pipes through the airtight sealing layer.
Can also be used outdoors, e.g. for sub-roofs and for refurbishment vapour check.
Stick with TESCON VANA (included in the double packaging unit).

General conditions

The bonds should not be subjected to tensile strain.
Press firmly to secure the adhesive tape. Ensure there is sufficient back-pressure.
Windproof, airtight or rainproof seals can only be achieved on vapour retarding membranes, roof lining membranes or façade membranes that have been laid without folds or creases.
Ventilate regularly to prevent build-up of excessive humidity and use a dryer if necessary.

Substrate

Before sticking, subsurfaces should be brushed off, wiped clean with a cloth or cleaned using compressed air.
Adhesion to frozen surfaces is not possible. There must be no water-repellent substances (e.g. grease or silicone) on materials to be bonded. Subsurfaces must be sufficiently dry and have sufficient load-bearing capacity.

Permanent adhesion is achieved on all pro clima interior and exterior membranes, other vapour retarder and airtight membranes (e.g. those made of PE, PA, PP and aluminium) as well as other underlay/sarking and wall lining membranes (e.g. those made of PP and PET).
Adhesion and joints can be carried out on planed and painted wood, hard plastics and metal (e.g. pipes, windows etc.), hard wood-based panels (chipboard, OSB and plywood panels, MDF board and softwood fibre sub-roof panels).
Wood fibre sub-roof panels and smooth mineral subsurfaces require pre-treatment with TESCON PRIMER before bonding. Concrete or plaster subsurfaces must not be sandy or crumbling.

The best results in terms of structural stability are achieved on high-quality subsurfaces.
It is your responsibility to check the suitability of the subsurface; adhesion tests are recommended in certain cases.
Pretreatment with TESCON PRIMER is recommended in the case of subsurfaces with insufficient load-bearing capacity.
