About Tangit

Tangit is Henkel's brand for pipework and plumbing installation. With us it stands above all for two tasks that otherwise cause trouble every time: the subsequent sealing of house, cable and pipe penetrations with the 2K expansion resin M3000 and the bonding of ABS pipes in refrigeration and air-conditioning systems. In addition there are the swelling sealing hose for pressing water and the tools that belong with the two-component cartridges – static mixer, push-out plunger and all-metal gun.

The house entry is the place where water comes in

A core drill hole for water, electricity or fibre optic leaves an annular gap around the pipe. It is precisely there that water runs into the basement – not through the wall, but through the gap. Mortar helps only to a limited extent there: it shrinks, tears away from the pipe and does not move with it. A 2K expansion resin works differently. It is introduced as a liquid, foams up in the gap and fills it right into the undercut.

Orange is the expansion resin, grey the pipe, light the core drill hole. Without electricity, without water, without mixing by hand. Tangit M3000 comes as a coaxial cartridge; both components are brought together in the right ratio via a static mixer and run as a liquid into the gap, where they foam up. According to the product data, the resin is suitable for house and cable penetrations as well as for well construction, processable between +5 °C and +30 °C. After curing the filling stays in the gap, even if pipe and wall move differently.

In practice that means: the gap is cleaned, formed off at the bottom or stuffed with a cord, and the resin is introduced from above. The 150 ml cartridge is enough for a normal house entry, the 300 ml cartridge for larger openings. The static mixer is important: without it both components come out unmixed and do not cure.

Pressing or non-pressing water – the difference is set out in DIN 18533

Before a penetration is sealed, the question has to be clarified which water is present at all. The standard for the waterproofing of components in contact with the ground distinguishes by water exposure classes: ground moisture and non-pressing seepage water on the one hand, pressing water on the other. For the second group a waterproofing that merely keeps moisture away is no longer enough.

The water level decides the product. If groundwater or dammed-up seepage water stands against the basement wall, a pressure acts that a simple waterproofing does not absorb. According to the product data, the sealing hose M4082 can be used to DIN 18533 in W2.1-E, that is, for pressing water with moderate exposure; it swells on contact with water and closes the gap by itself – and can also be installed from the inside. Which water exposure class applies to the structure results from the ground conditions and design water level and is planned, not estimated.

Good to know

Tangit belongs to Henkel. The Düsseldorf group, by its own account, celebrates its 150th anniversary in 2026; its adhesive brands also include Pattex, Ponal and Teroson.
The coaxial cartridge needs no special device. Both components sit inside one another in one cartridge; an ordinary cartridge gun is enough, provided it can apply the pressure. The PP6 made of all metal is designed for this.
The static mixer is a wearing part. It becomes unusable after curing. Anyone who wants to continue processing an opened cartridge later needs a new one.
EN 14814 is the standard for pipe adhesives in pressure lines made of thermoplastics – the mention on the ABS adhesive is therefore not there for show but indicates suitability for pressure pipelines.
The sealing hose does not age in the container. According to the product data it can be stored indefinitely in the original container – unlike cartridge goods, which carry a best-before date.

Frequently asked questions about Tangit

How do I seal a house entry retrospectively?

The annular gap between core drill hole and pipe is first cleaned and closed at the bottom – with formwork or a stuffed-in cord so that nothing runs through. Then M3000 is introduced from above via the static mixer; it flows into the gap and foams up there. The 150 ml cartridge covers a normal penetration. If pressing water is present, a swelling sealing hose additionally belongs in the build-up.

What exactly does “pressing water” mean?

That water stands against the component with hydrostatic pressure – for example because the groundwater level lies above the basement exterior wall or seepage water dams up in a cohesive soil. DIN 18533 assigns such cases to the water exposure classes W2.1-E and W2.2-E. Ground moisture and non-pressing seepage water are the easier case. Which class applies results from the ground survey and design water level – that is a planning question, not an assessment on the building site.

Do I need a special gun for M3000?

No, a coaxial cartridge can be processed with a strong ordinary cartridge gun – all that is needed is the screwed-on static mixer, which brings both components together in the right ratio. Anyone who works with it regularly is better served by the PP6 made of all metal: it transmits more force and lasts longer than plastic devices.

What is the ABS adhesive intended for?

For pipes and fittings made of acrylonitrile butadiene styrene, as they are mainly installed in refrigeration and air-conditioning systems. The Tangit ABS adhesive is specified to EN 14814 and EN ISO 15493 and is thus suitable for pressure pipelines; it also bridges joint gaps that fit less precisely. For PVC-U or PE, other adhesives or joining methods apply – the material information on the pipe is binding here.
