Main Purpose

Creates a flexible airtight seal around cables and pipes so that they can safely penetrate a building’s airtight layer.



Kaflex is a flexible heat resistant rubberised grommet supplied as either a self-adhesive patch with an integrated grommet or as a 150mm square rubber grommet that is sealed with tape. It is compatible with 5-12mm diameter cables and pipes. Versions are available for sealing single, double and multiple cables and pipes in one. Kaflex uses Tescon Vana as the adhesive. This is a tape that has been 3rd party tested and proved to remain airtight for at least 100 years.  

Where to use it:

Pro Clima Kaflex rubber grommets can be used on 5-12mm diameter cables and pipes where you have access to one end. Access is required so the grommet can be slid onto the pipe or cable like a tight-fitting collar.

Kaflex grommets can be used internally or externally. The solid acrylic adhesive used for sticking the grommet to an airtight barrier will permanently stick to any airtight or windtight membrane, wood-based panel/board, smooth planed or painted timber, metal or plastic (i.e. anything Tescon Vana airtight tape would stick to).

What it does:

Kaflex grommets create airtight seals around cables and pipes that penetrate a building’s airtightness layer. The grommet grips the pipe or cable but is not stuck to it, so it can be pulled or re-positioned as required without affecting the airtightness in any way.

Kaflex Mono and Kaflex Duo are a patch of Tescon Vana airtight tape with an integrated stretchable heat resistant EPDM rubber grommet in the middle. Kaflex Mono has one pre-cut hole to seal one cable or pipe. Kaflex Duo has two holes to seal two pipes or cables.

Kaflex Multi is a 150 x 150mm EPDM rubber grommet large enough for sealing pipes and up to 16 cables. It is supplied with an easy-to-use hole punch and template to allow the installer to precisely cut the holes they need in the most convenient configuration. A length of Tescon Vana airtight tape is also supplied so the installer can seal the rubber grommet to the airtight layer that the pipes or cables pass through.

Pro Clima Kaflex grommets can be left exposed to UV and the weather for up to 6 months during construction (before the building is finished).

How it works:

The pre-cut undersized holes of Kaflex Mono and Kaflex Duo tightly grip the outer surface of cables and pipes so that once the grommet is stuck down or taped onto an airtight barrier, air leakage through gaps around the cables or pipes is eliminated. The same principle applies for Kaflex Multi with undersized holes punched by the installer in whatever configuration is required.

Use it on:

Internal or external roofs, walls and floors on cables and pipes of 5-12mm diameter. The grommet will stick to any wind or airtight membrane, smooth timber, planed or painted timber, wood-based panel or board, concrete, metal and plastic. The end of the cable or pipe must be accessible so it can be fed through the grommet.
