These products are used to insulate, protect, and bundle wires and cables in applications where a controlled shrink ratio and consistent wall thickness are required. The tubing is offered in a 2:1 shrink ratio, meaning the inner diameter after shrinking is half the supplied inner diameter. This ratio is common for general-purpose electrical insulation and provides a balance between coverage and ease of installation. Sizes range from 1/16 inch to 3/8 inch inner diameter before shrinking, with lengths from 6 inches to 100 feet depending on the SKU. Color options are primarily black, though other colors may be available upon request. The medical-grade tubing is supplied in 5-packs or 100-foot lengths and is intended for insulating and protecting wires, cables, and components in medical and food-grade environments. These products are manufactured to meet typical industry standards for heat shrink tubing, though specific certifications should be verified with the manufacturer. 3G Electric stocks a range of INSULTAB heat shrink tubing SKUs, including assortment kits with mini-spool pull-paks, medical-grade cut lengths, and bulk spools. The assortment kits are useful for maintenance and repair operations that require multiple sizes in a single package. The medical-grade tubing is available in inner diameters of 0.13 inch, 0.19 inch, 0.38 inch, and 0.5 inch, with 2:1 shrink ratios. These products are suitable for applications where a clean, professional finish is needed, and where the tubing must withstand typical operating temperatures for PVC-based heat shrink. 3G Electric supports the INSULTAB line by maintaining inventory across multiple SKUs and providing logistics support for global delivery. Technical buyers can reference manufacturer part numbers such as HS-714-3/16 Blk 6, HS-714-1/2 Blk 6, and 30-PVC-175BK when specifying or cross-referencing. The product data includes inner diameter before shrinking, length, color, and shrink ratio, allowing engineers to select the correct size for their wire bundle. For applications requiring a specific shrink ratio or material, buyers should confirm the tubing's temperature rating and chemical resistance with the manufacturer's datasheet. 3G Electric does not manufacture these products; it distributes them as part of its industrial equipment catalog.

Frequently asked questions

Common questions about INSULTAB from 3G Electric.

What sizes of INSULTAB heat shrink tubing are available?

INSULTAB heat shrink tubing is available in inner diameters before shrinking ranging from 1/16 inch to 3/8 inch for general-purpose PVC tubing, and from 0.13 inch to 0.5 inch for medical-grade tubing. Assortment kits include multiple sizes, such as 3/32 inch, 1/8 inch, 3/16 inch, 1/4 inch, and 3/8 inch. Lengths vary from 6-inch cut pieces to 100-foot spools. The shrink ratio is 2:1, meaning the tubing will shrink to half its supplied inner diameter. When selecting a size, choose an inner diameter that is slightly larger than the largest component in the wire bundle to allow for easy installation before shrinking.

What is the difference between INSULTAB medical-grade and standard heat shrink tubing?

INSULTAB medical-grade heat shrink tubing is formulated for use in medical and food-grade environments, where material composition and cleanliness are critical. It is supplied in black, with a 2:1 shrink ratio, and is available in 5-packs or 100-foot lengths. Standard PVC heat shrink tubing is intended for general-purpose electrical insulation and is available in assortment kits and bulk spools. Both types are used for insulating, protecting, and bundling wires and cables. The medical-grade version may have additional testing or documentation available upon request. Always verify the specific material and compliance requirements for your application with the manufacturer's datasheet.

What is the shrink ratio of INSULTAB heat shrink tubing?

INSULTAB heat shrink tubing listed in the 3G Electric catalog has a 2:1 shrink ratio. This means the tubing will shrink to half of its supplied inner diameter when heated above its shrink temperature. For example, a 0.19-inch inner diameter tubing will shrink to approximately 0.095 inch. The 2:1 ratio is suitable for many electrical insulation and bundling applications. It provides a balance between shrinkage and wall thickness. When selecting tubing, ensure the expanded inner diameter fits over the components and the recovered inner diameter is tight enough to hold the bundle. Consult the manufacturer's datasheet for specific shrink temperature and recovery time.

Can INSULTAB heat shrink tubing be used for food-grade applications?

INSULTAB offers medical-grade heat shrink tubing that may be suitable for food-grade applications, but the specific compliance with food-contact regulations should be verified with the manufacturer. The medical-grade tubing is supplied in black, with a 2:1 shrink ratio, and is available in various inner diameters and lengths. It is used for insulating and protecting wires, cables, and components. For food-grade applications, the tubing must meet relevant FDA or equivalent regulations for food-contact materials. 3G Electric recommends requesting a certificate of compliance or material safety data sheet from the manufacturer before use in food-processing environments. The product data in the catalog does not include food-grade certifications.

What lengths are available for INSULTAB medical-grade heat shrink tubing?

INSULTAB medical-grade heat shrink tubing is available in 6-inch lengths, 4-foot lengths, and 100-foot lengths, depending on the SKU. The 6-inch and 4-foot lengths are supplied in 5-packs, while the 100-foot length is supplied as a single spool. Inner diameters before shrinking include 0.13 inch, 0.19 inch, 0.38 inch, and 0.5 inch. All have a 2:1 shrink ratio and are black. When ordering, specify the manufacturer part number, such as HS-714-3/16 Blk 6 for a 6-inch length with 0.19-inch inner diameter. 3G Electric stocks multiple lengths to accommodate different project sizes.

How do I select the correct INSULTAB heat shrink tubing size for my wire bundle?

To select the correct INSULTAB heat shrink tubing size, measure the maximum diameter of the wire bundle or component to be covered. Choose a tubing with a supplied inner diameter that is at least 20-30% larger than the bundle diameter to allow for easy installation. Then, verify that the recovered inner diameter (half of the supplied inner diameter for a 2:1 ratio) is smaller than the bundle diameter to ensure a tight fit after shrinking. For example, a bundle with a 0.1-inch diameter could use a 0.13-inch inner diameter tubing, which shrinks to 0.065 inch. Consider the operating temperature and environmental exposure. Consult the manufacturer's datasheet for specific shrink temperature and recovery time.
