Why Choose the Partex HSKIT238.1 2:1 Heat Shrink Tubing Kit?
The Partex HSKIT238.1 is a professional 2:1 heat shrink tubing kit featuring tubing with a nominal supplied diameter of 38.1 mm and a nominal fully recovered diameter of 19 mm. Designed for electrical insulation, cable protection and professional wiring finishes, this heat shrink sleeving provides a practical solution for covering appropriately sized electrical cables, conductor bundles, wiring transitions and cable connections.
Part of the Partex heat shrink tubing range, HSKIT238.1 uses heat-activated radial contraction to form a close-fitting protective sleeve around compatible cables and components. When heated correctly, the tubing contracts around the underlying assembly, helping protect covered wiring against abrasion, rubbing and routine handling damage. Its relatively large supplied diameter makes it particularly useful for applications where smaller heat shrink tubing cannot accommodate the cable or connection before installation.
With a 2:1 nominal shrink ratio, the tubing can contract from its supplied diameter of 38.1 mm towards a recovered diameter of 19 mm. Supplied in a convenient kit format, Partex HSKIT238.1 is suitable for electrical contractors, control panel manufacturers, industrial maintenance engineers and OEM equipment builders requiring protective heat shrink sleeving for medium-to-large cable assemblies.

Reliable Insulation and Mechanical Protection for Electrical Cable Assemblies
The Partex HSKIT238.1 provides a practical solution for protecting electrical cables, conductor bundles and suitable connections that require a relatively large sleeve opening. Its nominal 38.1 mm supplied diameter allows the tubing to be positioned over appropriately sized cable assemblies, wiring transitions and components before heat is applied. Once heated correctly, the tubing contracts around the assembly to create a close-fitting protective covering.
The 2:1 shrink ratio provides flexibility when selecting tubing for cable assemblies with moderate variations in diameter. The nominal fully recovered diameter of 19 mm allows the tubing to reduce to approximately half its original diameter. For effective installation, the tubing must fit over the largest section of the assembly before shrinking and recover sufficiently to grip the intended surface.
Heat shrink tubing is particularly useful in industrial control panels, electrical equipment manufacturing and cable harness assembly, where cables may require additional insulation or mechanical protection. HSKIT238.1 can provide a tidy covering around compatible cable transitions, grouped conductors and suitable electrical connections while helping reduce exposure to abrasion and routine handling damage.
The kit format makes HSKIT238.1 convenient for electrical workshops, maintenance departments and installation projects. Installers can prepare an appropriate length of tubing, slide it over the cable assembly and apply controlled heat using a suitable heat gun. Even heating around the circumference helps achieve consistent recovery without overheating the underlying cable insulation or adjacent components.
Where a cable assembly contains substantial changes in diameter, the installer should confirm that the 2:1 recovery range is sufficient. Applications requiring greater dimensional recovery may benefit from an appropriately specified 3:1 heat shrink product. Similarly, where moisture sealing is required, an adhesive-lined product specifically designed for environmental protection should be selected rather than assuming standard heat shrink tubing provides a watertight seal.

Frequently Asked Questions
What is the Partex HSKIT238.1 heat shrink tubing kit used for?
The Partex HSKIT238.1 is used for electrical insulation, mechanical protection and professional finishing of appropriately sized cables, conductor bundles and electrical connections. Typical applications include control panel wiring, machinery installations, industrial cable harnesses and electrical maintenance.
What does the 2:1 shrink ratio mean?
A 2:1 shrink ratio means the tubing can contract to approximately half its original nominal diameter when fully recovered under suitable heating conditions. This allows it to fit closely around appropriately sized cables and components.
What are the supplied and recovered diameters of HSKIT238.1?
The tubing has a nominal supplied diameter of 38.1 mm and a nominal fully recovered diameter of 19 mm. The cable or component must fit inside the tubing before shrinking, and the tubing must recover sufficiently around the finished assembly.
Is Partex HSKIT238.1 supplied as a kit?
Yes. HSKIT238.1 is supplied in kit format and is identified by its 38.1/19 mm tubing dimensions and 2:1 shrink ratio. The precise number of pieces, individual lengths and any additional kit contents should be confirmed from the supplied product information.
Is HSKIT238.1 suitable for larger electrical cables and conductor bundles?
Yes. Its 38.1 mm nominal supplied diameter makes HSKIT238.1 suitable for appropriately sized larger cables and conductor bundles. The tubing can recover towards a nominal diameter of 19 mm, so the finished cable diameter must be considered to ensure a suitable fit.
Can Partex HSKIT238.1 be used over cable joints and electrical terminations?
Yes, provided the joint or termination is appropriately sized and the tubing meets the electrical and mechanical requirements of the application. The tubing must fit over the largest part of the connection before shrinking and recover sufficiently to provide the intended coverage.
Is Partex HSKIT238.1 waterproof?
The tubing provides protective sleeving around suitable cables and connections, but waterproof or moisture-sealing performance should not be assumed without a confirmed product rating. For applications requiring environmental sealing, select an appropriately specified adhesive-lined heat shrink product.
How should the Partex HSKIT238.1 be installed?
Ensure the electrical circuit is safely isolated, prepare the required length of tubing and slide it over the cable or connection. Apply controlled, even heat using an appropriate heat gun until the tubing has contracted around the assembly. Allow it to cool before handling and avoid overheating the underlying cable insulation or nearby components.
