PROMASEAL® Retrofit Collar (circular base)is designed to be fitted around installed pipes that pass through floor slabs and have been tested with uPVC, HDPE and ABS pipes up to 150mm diameter. The larger opening within the collars will accommodate pipes (and uPVC pipe fittings) that have differing outside diameters.

PROMASEAL® Retrofit Collar should be unclipped, placed around the pipe, reclipped and pushed tight to the substrate.

Both square and circular based PROMASEAL® Retrofit Collars can be split in order to be retrofitted or relocated when necessary.
