PROMASEAL® Conduit Collar

PROMASEAL® Conduit Collar is designed for retrofitting around small (<32mm) plastic conduit pipes that pass through fire floor or wall slabs. It comes in one size (32mm) and can be used on smaller diameter conduits without modification. The collar is fixed to the floors/walls with two brackets.

Insulation criteria will vary depending on types of the plastic pipes and the penetrating building element through which the collar passes.

The collar is supplied pre-made with an internal diameter of 32mm, however no change is required to the collar for pipes of smaller diameters.
