RectorSeal Duct Seal Compound

from $23.00

RectorSeal Duct Seal Compound is a soft, permanently pliable, non-toxic putty-type compound designed for sealing around electrical conduits, boxes, service mast entries, flashings and other irregular openings. It adheres to most clean, dry surfaces and can be shaped by hand to suit cables, conduits and uneven penetrations.

Because it remains soft rather than curing hard, it can be removed and reused where future access or adjustment is required. This makes it particularly useful around cable entries and service penetrations where a neat, controllable seal is needed without permanently locking the installation in place.
