TE Connectivity Black Heat Shrink Tubing, 9.5mm, 2:1, 10m Length

BMUK Part # :-219-6513
BrandTE Connectivity
Mfr. Part No.DR-25-3/8-0-10

Product Details

DR-25 Heat shrink Tubing (Shrink Ratio 2:1)

Robust and flexible heat shrink tubing. It protects wires and cables against damage from chemicals, abrasion, and fluids. The tubing is ideal for use in high temperature environments as it has been specially designed for long term heat resistance and is flame retardant.

Features and Benefits
• Offers excellent protection and insulation
• Provides strain relief
• Performs well under long-term heat exposure
• The tubing is printed with the product description and size
• Shrink ratio of 2:1
• Use with System 25 range products for a complete cable harness system
