£31.20
The Cembre TBS190X5BR is a premium-quality 2:1 heat shrink tubing designed to provide reliable electrical insulation, mechanical protection and cable identification for industrial and commercial wiring applications. Manufactured from durable halogen-free polyolefin, it delivers long-lasting protection against abrasion, moisture, chemicals and environmental contaminants while maintaining excellent electrical performance.
Designed for electricians, panel builders and maintenance engineers, the TBS190X5BR provides fast, consistent shrink performance for insulating cable joints, wire harnesses and electrical terminations. Its flexible construction makes installation straightforward while ensuring dependable protection in demanding environments.
With a 19 mm pre-shrink internal diameter, 9 mm recovered diameter and supplied in a 5 metre coil, the TBS190X5BR is ideal for protecting larger cables, terminals and electrical assemblies requiring durable insulation and strain relief.
Heat shrink tubing provides durable insulation by shrinking tightly around cables, connectors and terminals when heat is applied. This creates a strong protective barrier that improves electrical safety, protects against mechanical wear and extends the service life of cable assemblies.
The Cembre Thermoblock range is trusted throughout industrial automation, panel building and electrical maintenance applications where dependable insulation and long-term performance are essential.
