Southwire 1901 Seal Flex Compound 1 Lb

Product Description

The SOUTHWIRE 1901 is a seal flex compound used to create weatherproof, airtight seals around electrical conduit entries, fittings, and enclosure penetrations. This pliable, non-hardening compound fills voids and gaps to block moisture, air, and insects from entering electrical boxes, panels, and junction points. It is a standard material in commercial and residential electrical work where conduit sealing is required by code. Licensed electricians and electrical contractors apply this compound during rough-in and finish stages to maintain enclosure integrity and meet inspection requirements.

The SOUTHWIRE 1901 seal flex compound is suited for use at conduit entry points on weatherproof enclosures, meter bases, load centers, and similar electrical equipment. It performs in both indoor and outdoor applications where a durable, flexible seal is needed to prevent environmental intrusion. The compound remains workable after application, accommodating minor conduit movement without cracking or losing adhesion.
