• Fire penetration sealing of flammable supply/disposal lines and pre-insulated district heating pipes with special requirements
• For flammable pipes
• Building services: wastewater, rainwater, drinking water, heating, compressed air, pneumatic tube

• For walls and ceilings with pressure-tight requirements
• For indoor and outdoor use
• For aluminum pipes

For watertight and / or gas-tight partitioning of pipes:

• made of steel, stainless steel, copper, cast Ø ≤ 325 mm
• made of aluminum Ø ≤ 160 mm
• Pre-insulated district heating pipes 1) made of steel, stainless steel, copper, cast iron, total Ø ≤ 315 mm

Approved for insulation
• On both sides of the bulkhead, a mineral fiber wire mesh mat must be attached to the pipeline at least 700 mm long with an insulation thickness of ≥ 80 mm
• PUR foam including PE-HD jacket pipe (district heating)


1) only wall bushings (wall thickness> 240 mm), for details see test certificate

• Can be used in core bores or special fiber cement casing pipes.

• Up to 4 pipes (Ø ≤ 60.3 mm) at the same time through one bushing.
• in ceilings made of aerated concrete, reinforced concrete, concrete with a thickness ≥ 150 mm *
• in walls made of aerated concrete, reinforced concrete, concrete, masonry with a thickness ≥ 100 mm *
• 2 wall protection packs are required for wall thicknesses ≥ 400 mm

* Observe general building inspectorate approval, since depending on the pipe dimension, larger component thicknesses are required.
For bushings without casing pipe, component thickness ≥ 175 mm.
