The GARDNER BENDER DS-130 is a duct seal compound supplied as a 1-pound pug bar, designed to seal openings where electrical conduit, cables, and pipes penetrate walls, floors, and ceilings. This compound prevents the passage of air, gases, moisture, and pests through conduit entries and building openings. It is a 99% solid, coil-based formulation that remains permanently pliable, making it a reliable choice for sealing both new construction and retrofit installations. Electricians and electrical contractors are the primary installers. The DS-130 adheres at temperatures as low as -20 degrees F and carries a flash point above 550 degrees F.
The DS-130 is used in residential and commercial electrical installations wherever conduit or cable penetrates a fire-rated or non-fire-rated wall, floor, or ceiling assembly. It is commonly applied around service entrance conduits, panel feeders, and underground conduit stub-ups entering a structure. The compound is worked by hand into the opening around the conduit and conforms readily to irregular shapes. It is intended for interior use only and is not rated for outdoor or exposed-weather applications.

Installation Notes
Installation is typically performed by a licensed electrician. De-energize circuits and ensure conduit is clean and dry before applying the compound. Work the compound firmly into the annular space around the conduit by hand until the opening is fully sealed with no voids. This product is not approved for outdoor, submerged, or exposed-weather use - consult applicable NEC requirements for conduit sealing in hazardous or wet locations where listed sealing fittings may be required instead.
