3M 7000132544 Mastic Tape Pad 2.5x3.75 in Cable Seal

Product Description

The 3M 7000132544 is a preformed mastic tape pad used for insulating, padding, and sealing high voltage cables and cable accessories. Each pad measures 2.5 inches by 3.75 inches and is 125 mils thick. The conformable, tacky mastic material presses firmly over irregular surfaces and delivers excellent moisture resistance. A release liner protects the adhesive until installation. The pad is temperature-rated at 176 degrees F and features self-healing characteristics after puncture or cut. Licensed electricians and cable splicing technicians are the primary installers of this product.

This mastic tape pad is suited for high voltage cable splicing and termination work in both commercial and industrial applications. The preformed pad format speeds up the sealing step compared to cutting tape from a roll, making it a practical choice on jobsites where consistent pad geometry is required. It conforms to irregular cable geometries, connector bodies, and splice sleeves. Pads are packaged in inner packs of 10, with 40 pads per case.

Key Features

• Preformed pad format at 2.5 inches by 3.75 inches for consistent sizing on every splice
• 125-mil thickness provides substantial insulating and protective mass
• Conformable, tacky mastic bonds firmly to irregular and curved surfaces
• Superior moisture resistance protects cable connections from environmental ingress
• Self-healing after puncture or cut, maintaining seal integrity in demanding installations
• Release liner protects adhesive surface and allows clean, controlled application

Compatibility

Designed as an OEM-style replacement pad for high voltage cable insulation and sealing applications where conformable mastic material is specified.

Installation Notes

Installation is performed by licensed electricians following applicable NEC guidelines for high voltage cable splicing and termination. De-energize and verify the circuit is at zero voltage before handling any cable splice components. Remove the release liner immediately before pressing the pad firmly over the cable or connector surface, working out air pockets as the mastic conforms to the substrate. Follow the cable manufacturer and splice kit instructions for layering sequence and overlap requirements.
