## Long description

The Erko RTCK thin-walled heat shrink tubing is a professional-grade solution designed for reliable electrical insulation and environmental sealing. Featuring an integrated internal adhesive layer, this tubing melts upon heating to create a moisture-resistant barrier that protects connections from corrosion and mechanical damage. The transparent design allows for easy inspection of the underlying wire or connection, making it a versatile choice for various technical applications.
Advantages
This heat shrink tubing offers a high shrink ratio of 3:1, which allows it to effectively accommodate irregular shapes and varying cable diameters ranging from 9 mm down to 3 mm. The thin-walled construction ensures flexibility while maintaining structural integrity, and the internal adhesive provides a superior bond to most cable jackets and connector materials. Its durability against environmental factors ensures long-term performance in both indoor and outdoor settings.
Suitable for
Electrical connection insulation
Cable repair and splicing
Wire bundling and organization
Moisture-proofing sensitive electronic components
Professional industrial and domestic electrical installations
When it may not be suitable
This tubing is not intended for use in high-temperature environments that exceed the material's thermal rating or for applications requiring extreme mechanical abrasion resistance. It should not be used as a primary structural support for heavy cables.
Key specifications
Shrink ratio: 3:1
Diameter range: 9 mm to 3 mm
Material: Thin-walled polyolefin with internal adhesive
Color: Transparent
Length: 1 meter
How to use
To use the Erko RTCK tubing, first cut a piece to the desired length, ensuring it extends slightly beyond the area to be covered. Slide the tubing over the wire or connection. Apply heat evenly using a heat gun, starting from the center and moving toward the ends to allow the adhesive to flow and the tubing to shrink securely around the object. Allow the connection to cool completely before handling to ensure the adhesive has set properly.
What to consider before purchase
Ensure the initial diameter of 9 mm is sufficient to slide over your specific connector or cable assembly.
Verify that the final shrunk diameter of 3 mm provides a tight fit for your wire gauge.
Confirm that the transparent material is suitable for your aesthetic or inspection requirements.
Usage recommendations
For optimal results, use a controlled heat source such as a professional heat gun rather than an open flame to prevent scorching the material and to ensure uniform shrinkage of the adhesive layer.
