Single Wall Sleeves,Single Wall Tubing
High-Temperature Resistance:
This Heat Shrink Tube offers excellent physic chemical and electrical performance, ensuring reliable insulation protection for electrical applications. it can withstand continuous operating temperatures between -40°C and 125°C, making it suitable for demanding environments.
Waterproofing Capability:
The PE material used in this product provides a waterproof seal, ensuring the safety and integrity of electrical connections in humid or wet conditions. This is particularly beneficial for users working with electrical components in harsh environments.
Easy to Apply:
The Heat Shrink Tube has a shrink ratio of 2:1, allowing for a snug fit on bus bars and other electrical components. This simplistic the application process, reducing the risk of errors and ensuring a secure seal.
Customization Options:
This product is available in various colors, including standard red, yellow, and green, and other colors can be requested by the user. This flexibility makes it easy for users to match the Heat Shrink Tube to their specific requirements.
