HellermannTyton Heat Shrink Tubing Brown 12.7 mm Sleeve Diameter x 200 mm Length 3:1 Ratio 308-31214 HIS-3-BAG-12/4-PO-X-BN

HellermannTyton 308-31214 HIS-3-BAG-12/4-PO-X-BN heat shrink tubing is a flexible, thin-wall tubing made from cross-linked polyolefin designed to protect cables and provide reliable electrical insulation. The tubing offers a sleeve diameter of 12.7 mm and a length of 200 mm, with a 3:1 shrink ratio that ensures the tube contracts to a third of its original diameter when heat is applied.

This brown heat shrink tubing is flame-retardant and provides a dielectric strength of 32 kV/mm, making it ideal for insulating and protecting wires in demanding electrical applications. Its operating temperature range from -55°C to +135°C ensures performance in harsh environmental conditions. The tubing is pre-cut into 10 pieces per bag to facilitate quick and efficient installation.

The heat shrink tubing meets UL standards and military specifications SAE-AMS-DTL-23053/5 Class 1 and 3, providing quality assurance suitable for industrial, electrical, consumer electronics, transportation, and robotics applications. While not halogen-free, it remains suitable for environments requiring flame retardancy and robust electrical insulation.

The HIS-3 BAG Series is recommended for cable joints and terminations, offering excellent cable protection and insulation with easy application using standard heat guns operating above 100°C. It resists impact and abrasion, ensuring durability and long-term performance of protected cables.

The tubing is made of tough cross-linked polyolefin for impact and abrasion resistance. It offers a high dielectric strength of 32 kV/mm for electrical insulation. Flame-retardant material prevents fire propagation in sensitive environments.

Pre-cut pieces enhance installation speed and accuracy. Supports extreme temperature ranges from -55°C to +135°C. Package includes 10 pre-cut heat shrink tubing pieces per bag. Ideal for consumer electronics, transportation, and robotics system HVAC and electrical applications.

Complies with UL and MIL standards ensuring safety and reliability. 3:1 shrink ratio enables effective size reduction when heated. Reliable cable protection, insulation, and flame retardancy.
