3M 7000031582 Mastic Strip Motor Lead Sealing

Product Description

The 3M 7000031582 is a mastic strip designed for electrical sealing applications in motor and cable work. Each strip is a short length of thin mastic material with a removable liner on both sides, making it easy to handle and apply without contaminating the adhesive surface before use. The strips conform to irregular surfaces and create a reliable seal around motor leads and similar penetrations. Electricians and motor service technicians use this product to restore insulation integrity after reworking or reentering motor lead terminations.

This mastic strip is suited for use in both residential and commercial electrical applications wherever a flexible, conformable sealing material is needed. It is commonly applied after reentering a motor lead splice to restore the moisture and environmental seal around the conductor. It also works in small-scale sealing tasks where a pliable mastic filler is appropriate, such as void filling around cable entries or minor insulation repair work.

Key Features

• Removable liner on each side protects the mastic surface until ready for application
• Thin, flexible mastic construction conforms to irregular and curved surfaces
• Suited for motor lead reentry sealing after splice rework
• Usable in small general sealing applications around electrical penetrations
• Sold individually per each unit of measure

Compatibility

Designed as an OEM-style sealing strip for use in motor lead reentry and small electrical sealing applications typical in commercial and residential electrical service work.

Installation Notes

Installation is performed by licensed electricians or qualified motor service technicians. De-energize and lock out the equipment before working on any motor leads or splices per NFPA 70E requirements. Remove both liners immediately before application and press the mastic strip firmly into place to ensure full contact and an air-free seal. Do not stretch the strip excessively, as this may reduce sealing effectiveness.
