## Summary description

Thin-wall heat shrink tube Shumee CR 12.7/6.4 in blue, nominal diameter 12.7 mm shrinking to 6.4 mm (1/2" to 1/4") supplied as 1 m lengths in a pack of 50. Designed for electrical insulation, cable repair, sealing and strain relief on wiring connections. Provides protective coverage and color identification for wires and terminals.

## Long description

Shumee thin-wall heat shrink tube CR 12.7/6.4 in blue is a flexible insulating sleeve supplied as 1 m lengths in a pack of 50. With a nominal diameter of 12.7 mm that shrinks to 6.4 mm, this tube is intended for electrical insulation, cable repair, sealing and providing strain relief on wiring connections. The blue color also serves as a visual identifier for wires and terminals in installations.
Advantages
The thin-wall construction allows fast, even shrinking with minimal bulk after application, making it suitable where space is limited. It provides reliable electrical insulation and protection from abrasion and light mechanical stress while maintaining flexibility. Supplied in pre-cut 1 m pieces and packaged in a quantity of 50, the tubes are convenient for repetitive installation tasks and small batch wiring projects. The blue color simplifies circuit identification and color-coded organization.
Suitable for
 Electrical insulation of splices and exposed conductors
 Cable repair and covering damaged insulation
 Providing strain relief on soldered or crimped connections
 Color-coding wires and terminals in panels or harnesses
 General light-duty protection in electronics and automotive low-voltage wiring
When it may not be suitable
This thin-wall heat shrink is not intended for high-voltage insulation applications where thicker, high-dielectric materials are required. It is also unsuitable for sealing or protecting components exposed to continuous high temperatures, aggressive chemicals, or heavy mechanical abrasion. For environments requiring flame retardancy, high temperature resistance, or specialized adhesive-lined sealing, choose a product specifically rated for those conditions.
Key specifications
 Initial outer diameter: 12.7 mm
 Recovered outer diameter: 6.4 mm
 Wall type: thin-wall
 Length per piece: 1 m
 Color: blue
 Quantity: 50 pieces per pack
 Typical use: electrical insulation, strain relief, cable repair
How to use
Slide the heat shrink tube over the connection or cable section before making the final joint, or position it over the area to be repaired. Apply heat evenly using a heat gun, hot air tool, or controlled flame at a safe distance until the tube shrinks uniformly and fits snugly around the conductor or joint. Allow the tubing to cool and set before subjecting the connection to mechanical stress. For best results, avoid direct flame contact and maintain an even sweeping motion when using a heat source.
What to consider before purchase
 Confirm that the recovered diameter (6.4 mm) will fit tightly over your insulated conductors or connectors after shrinkage.
 Check that thin-wall construction meets your required level of mechanical protection and electrical insulation.
 Ensure blue color is appropriate for your color-coding or identification scheme.
 Evaluate environmental conditions (temperature, chemicals, abrasion) to determine if a specialty tubing is needed.
Usage recommendations
Use a regulated heat gun at moderate temperature settings and keep the nozzle moving to achieve uniform shrinkage. For strain relief, position the tube to cover both the conductor insulation and the connector body. Store the tubes in a dry place away from direct sunlight to preserve material properties.
