3M 7000132399 Heat Shrinkable Splice Kit 33 Inch

Product Description

The 3M 7000132399 is a heat shrinkable splice jacket kit designed for water-tight rejacketing of jacketed concentric neutral (JCN) cable splices. Part of the 3M HSJ Series, this kit features an adhesive-lined sleeve that creates a sealed, moisture-resistant enclosure when heat is applied. The sleeve measures 33 inches in length with an expanded inside diameter of 2.5 inches, making it suitable for medium-voltage cable splice work. Electrical linemen and utility cable splicing crews rely on this type of product to restore jacket integrity after field splicing operations.

This kit is intended for use in underground and direct-burial cable splice applications where JCN cables require rejacketing after a splice has been completed. The adhesive lining bonds to the cable jacket material as the sleeve shrinks, forming a barrier against water ingress and environmental contamination. It is commonly used in utility distribution, commercial electrical infrastructure, and industrial cable installations where splice longevity and moisture protection are critical requirements.

Key Features

• Adhesive-lined sleeve provides water-tight seal over completed JCN cable splices
• Sleeve length of 33 inches accommodates standard medium-voltage splice assemblies
• Expanded sleeve inside diameter of 2.5 inches fits over a range of cable and splice body sizes
• Heat-shrink activation bonds adhesive lining directly to cable jacket surface
• Sold as individual kit; available 10 per case

Compatibility

Designed for rejacketing of JCN cable splices as an OEM-style sleeve kit in the 3M HSJ Series. Specific compatible cable sizes or splice body models were not identified in the available product data.

Installation Notes

Installation is typically performed by licensed electricians or qualified utility cable splicers following applicable NEC and utility work practice guidelines. De-energize and isolate the cable circuit completely before beginning any splice rejacketing work. Apply heat evenly along the sleeve using an appropriate torch or heat gun, working from the center outward to prevent air pockets. Do not overheat the sleeve, as excessive temperature can compromise the adhesive lining and sleeve integrity.
