The HellermannTyton ShrinKit 321 is an essential, professional-grade heat shrink tubing set designed for electrical contractors, DIY enthusiasts, and technicians who need a versatile solution for cable insulation, strain relief, and color-coding. Featuring 975 pieces of polyolefin tubing with a 3:1 shrink ratio, this kit offers exceptional protection for cable diameters ranging from 1 mm to 20 mm. While the kit provides unmatched variety and convenience, users should note that the heat gun required for activation is not included, and consistent heat application is necessary to ensure a smooth, uniform shrink.

Yes, the polyolefin material is durable; however, ensure all connections are properly sealed to prevent water ingress.
A standard hair dryer is generally not hot enough. A dedicated heat gun is recommended for consistent, professional results.
The kit is designed to effectively cover application diameters ranging from 1 mm to 20 mm.
Yes, the organizer box features adjustable compartments to help you sort the 975 pieces by size or color as needed.
The ShrinKit 321 polyolefin material is engineered for general electrical use; check the technical datasheet if your project requires strict halogen-free compliance.
Reduce the heat gun temperature or keep the heat source further away from the tubing during application.
Ensure the selected tubing size is appropriate for the object diameter and that you are using the correct 3:1 ratio tubing for the application.
Ensure the surface of the cable is clean and free of oil or debris before applying the heat shrink.
To use the ShrinKit 321, select a piece of tubing that is slightly larger than the cable diameter, slide it over the desired area, and apply heat using a controlled heat gun until the tubing is fully conformed to the wire. For best results, rotate the cable to ensure even heat distribution and avoid localized overheating that could burn the material. The tubing is compatible with standard copper and aluminum wiring found in typical consumer electronics, automotive, and household electrical systems. Store the organizer box in a cool, dry place away from direct sunlight to maintain the integrity of the polyolefin material over time.
