Heat-Shrink Tubing CellPack CR 19.1/9.5 3/4" Thin-Wall, Mixed Lengths (MPN 8-7202)

CellPack heat-shrink tubing CR 19.1/9.5 is a thin-wall shrink sleeve designed for use with 3/4" fittings. The tubing has a nominal outer diameter of 19.1 mm and a nominal inner diameter of 9.5 mm before shrinking. Supplied as a mixed-length set, this shrink sleeve is intended to provide electrical insulation, mechanical strain relief and protection from moisture and abrasion for cable joints, terminals and connectors in repair, harnessing and general electrical installation tasks.

Advantages

The thin-wall construction allows reliable shrinking with minimal bulk after heat application, producing a neat, low-profile finish. The material provides dependable electrical insulation and improves mechanical stability of splices and connector points. Its resistance to abrasion and environmental moisture protects connections in both indoor and sheltered outdoor environments. The mixed-length supply gives flexibility for different cable repair and harnessing situations without needing to cut multiple pieces from a single long tube.

Suitable for

• Repairing damaged cable insulation and restoring protective covers
• Providing strain relief for soldered joints, crimps and connector transitions
• Bundling and insulating wire harnesses in appliances, automotive and industrial equipment
• Protecting terminals and splices from abrasion and moisture in general electrical installations

How to use

Measure the section of cable or connector to be covered and select a sleeve length from the mixed set that provides complete coverage with a small overlap at each end. Clean and dry the surfaces to ensure good adhesion and electrical insulation. Slide the tubing into place and apply heat evenly using a heat gun or controlled flame source at recommended distance until the tubing uniformly shrinks and conforms to the underlying cable or connector. Allow the sleeve to cool before handling and test the mechanical stability and insulation integrity of the repaired section.

Usage recommendations

For consistent results use a regulated hot-air tool and maintain an even heating motion to avoid local overheating. Ensure the selected sleeve diameter and length provide full coverage after shrinking. For outdoor or high-moisture applications, combine with appropriate sealing or adhesive-lined products if higher environmental sealing is required.
