Need striped identification sleeving? Explore green/yellow heat shrink tubing. For ready-to-use assortments, ask about heat shrink tubing kits.
Match the Tubing to Your Assembly
2:1 Colored Tubing
For cable insulation and identification where the tubing can slide over the connection before heating. Compare supplied and recovered diameters in the chart below.
3:1 Colored Tubing
A higher shrink ratio accommodates a greater difference between the pass-over diameter and the cable diameter. The published 3:1 dimensions are the adhesive-lined range — see the 3:1 size chart below, or send both measurements and we will confirm the appropriate size and color.

PVC Colored Heat Shrink Tubing Size Chart
All dimensions are in millimeters. PVC is supplied in black, red, white, blue, yellow and clear; green is a custom-color enquiry rather than a standard option. Published working temperature is −55°C to 125°C, with a 70°C minimum shrink temperature and a 300 V rated voltage. Confirm the grade and color against your application before ordering.

3:1 Heat Shrink Tubing Size Chart (Adhesive-Lined)
The 3:1 range we publish dimensions for is adhesive-lined (dual-wall) heat shrink tubing. Published characteristics: 3:1 shrink ratio, 70°C minimum shrink temperature, 110°C full shrink temperature, −55°C to 125°C operating range, 10.4 MPa tensile strength and 15 kV/mm dielectric strength. The adhesive thickness column is the inner adhesive layer, which is what distinguishes this range from single-wall tubing. For single-wall 3:1 tubing in a specific color, send your pass-over diameter, recovered diameter and color and we will confirm what is available.

Find the right fit in three simple steps
01Measure the largest point
Measure the largest connector or joint the tubing must pass over. Allow installation clearance when choosing the supplied inside diameter.
02Check the recovered fit
The recovered inside diameter must be smaller than the cable or joint being covered. Check the selected product’s recovery range and installation guidance.
03Choose color & quantity
Include the material, shrink ratio, nominal size and meters needed for each color. Tell us if you need rolls or an assortment.
Sizing example: 3 mm cable, 4 mm joint
5 mm nominal tubing is a candidate for this assembly: its supplied inside diameter is 5.5 ± 0.2 mm, and its recovered inside diameter is 2.50 mm.
It can pass over the 4 mm joint and recover below the 3 mm cable diameter. Confirm fit and installation on your actual assembly before bulk ordering.
Make cable identification clearer with color
Red & black tubing
Use contrasting colors to distinguish cable groups in your documented assembly scheme. Supply the color legend with the harness so identification stays consistent.
Yellow, green & blue tubing
Separate circuits, equipment groups or signal paths visually. Choose colors to match your project documentation and applicable requirements.
White & clear tubing
Choose white for a light visual identifier or clear where you need to inspect what is underneath. Confirm readability and compatibility on the finished assembly.
Keep your color code consistent. Color alone does not establish a universal wiring code. Follow the requirements for your country, equipment and application, and document your identification scheme.
Order your colors, sizes and packaging
The published 2:1 range uses 25, 50, 100 or 200 meters per roll, depending on size. Send a line for each color and diameter so we can quote your exact combination.
Roll quantities
Specify meters per color and size. The size chart shows the published roll length for each entry.
Assorted colors
For multi colored heat shrink tubing assortments, send the required colors, sizes and quantities. Ask us to confirm the available packaging.
Quotation details
Include your delivery country and required date. MOQ, lead time and shipping terms will be confirmed with your quotation.
Colored Heat Shrink Tubing Questions
Which heat shrink tubing colors are available?
The published range includes black, red, yellow, green, blue, white and transparent (clear). Confirm the required color with your chosen material, ratio and size.
Are colored and coloured heat shrink tubing the same product?
Yes. “Colored” and “coloured” are spelling variations. Choose according to material, dimensions, shrink ratio and application rather than the spelling.
Does the color change the shrink ratio?
Select shrink ratio from the product specification. A red, yellow or green color does not by itself identify whether the tubing is 2:1 or 3:1.
Can I order red and black tubing together?
Include a separate quantity and size for each color in your enquiry. We will confirm the available combination and packaging.
Is all colored tubing waterproof?
Color does not establish a waterproof seal. If your application needs environmental sealing, discuss a suitable adhesive-lined heat shrink product and its installation requirements.
What information should I send for a quote?
Send the color, material, shrink ratio, size or cable/joint diameters, quantity, packaging preference, delivery country and required date.

Tell Us Your Colors. We’ll Help Specify the Tubing.
Tell us which colors you need, the tubing material, shrink ratio and quantity for each size. If you are unsure about sizing, include the outside diameter of your cable and the largest connector the tubing must pass over. Add your packaging preference, delivery country and required date so our team can review the combination and prepare a quotation for your project.
