Heat-shrink PermaSleeve tubing, Brady M7-094-1-342, clear, single-wire sleeve

Brady PermaSleeve heat-shrink tubing in clear single-wire sleeve format is designed to insulate and protect wire terminations and splices. The tubing provides a close-fitting, transparent covering after heat shrinkage that improves strain relief and offers basic environmental protection while maintaining visibility of underlying markings and conductor insulation. It is intended for use in electrical wiring, repairs, harness assembly and panel connections where a slim, clear protective sleeve is required.

Advantages

The clear heat-shrink PermaSleeve forms a tight, uniform fit around conductors after heat application, reducing movement at connection points and enhancing mechanical stability. Its transparency allows visual inspection of wire color and printed identifiers without removal. The material provides electrical insulation and a degree of moisture and abrasion resistance appropriate for indoor and protected environments. The single-wire sleeve format simplifies application on individual wires and small splices.

Suitable for

• Insulating and protecting single conductor terminations and splices
• Wire repair and patching in electrical systems
• Harness assembly where clear identification of wires is needed
• Panel and control cabinet connections requiring compact, transparent sleeves

Key specifications

• Product type: clear heat-shrink tubing for single wires
• Material: heat-shrinkable polymer providing electrical insulation
• Finish: transparent, allowing visual inspection of conductor insulation and markings
• Application: designed to shrink to a close-fitting sleeve around individual conductors and small splices
• Protection: provides strain relief, abrasion resistance and basic environmental sealing for indoor or protected installations

How to use

Cut the clear PermaSleeve to the appropriate length so it covers the termination or splice with a small overlap on each side. Slide the sleeve over the connector or splice before making the electrical connection when possible; for repairs, position the sleeve over the splice after joining. Apply heat evenly with a heat gun or other suitable heat source until the tubing contracts uniformly and conforms tightly to the wire and connector. Allow the sleeve to cool and inspect for complete shrinkage and intact transparency.

Usage recommendations

Use a regulated hot air tool to achieve even heating and avoid localized overheating. For outdoor or high-moisture applications, consider combining the clear PermaSleeve with additional sealing methods if greater environmental protection is required. Verify compatibility with wire insulation temperature ratings before applying heat.
