Why Choose the Partex HSKIT125.4 2:1 Heat Shrink Tubing Kit?
The Partex HSKIT125.4 is a practical 2:1 heat shrink tubing kit designed for electrical insulation, cable protection, wire identification and professional cable management. Featuring a nominal 25.4 mm supplied internal diameter and a 12.7 mm recovered internal diameter, the tubing contracts when heated to provide a close-fitting protective sleeve around appropriately sized cables, conductors and electrical components.
Manufactured by Partex, a specialist in cable identification and electrical installation products, the HSKIT125.4 offers a convenient solution for electrical contractors, control panel builders, maintenance engineers and industrial wiring professionals. Its 2:1 shrink ratio allows the tubing to be positioned over a cable or electrical connection before shrinking around the underlying component to provide additional insulation and mechanical protection.
Supplied in a kit pack format, the Partex HSKIT125.4 is intended for electrical installation, cable assembly and maintenance applications requiring heat shrink sleeving. The exact number of pieces, individual lengths and colour configuration have not been specified and should be confirmed against the manufacturer's kit contents before ordering.
With its 25.4 mm nominal supplied internal diameter, this heat shrink tubing is particularly useful for larger conductors, medium-sized cable bundles, electrical terminations and protective sleeving applications. It provides a practical way to create a neat, organised finish while helping protect underlying cable insulation against abrasion and everyday mechanical wear.

Reliable Electrical Insulation and Cable Protection
Heat shrink tubing is widely used in electrical and industrial installations to provide protective sleeving around conductors, cable connections and electrical components. When suitable heat is applied, the tubing contracts around the underlying component, creating a close-fitting covering that can help protect against abrasion and provide additional electrical insulation where the product is appropriately specified.
The Partex HSKIT125.4 features tubing with a 2:1 shrink ratio, allowing its nominal internal diameter to reduce from 25.4 mm to 12.7 mm. This makes it suitable for applications where the tubing must initially pass over a wider section of cable or connection before shrinking around the intended area.
The 25.4 mm supplied diameter is particularly useful for medium-sized cable assemblies, grouped conductors and suitably sized electrical connections. By selecting the correct tubing size, installers can create a neat protective finish that helps reduce direct exposure of the underlying cable surface to minor mechanical wear.
Heat shrink tubing can also support cable identification and organised wiring systems when used alongside suitable cable markers, labels or other identification products. Where colour-coded conductor identification is required, the tubing colour and identification method must comply with applicable electrical regulations. As the colour configuration of this kit has not been specified, no particular conductor identification function should be assumed.
For effective installation, ensure the supplied internal diameter is large enough to pass over the intended cable, connector or component and that the recovered diameter is suitable for achieving the required fit. Cut the tubing to the required length where appropriate, position it over the intended area and apply controlled, even heat using a suitable heat gun.
Follow the manufacturer's installation recommendations and avoid excessive heating of the tubing or underlying cable insulation. The tubing should not be used as a substitute for a correctly designed electrical connection, connector or mechanical strain relief where one is required.
Where a waterproof connection, adhesive seal or specified environmental barrier is required, select a heat shrink product with those verified properties. The HSKIT125.4 should not be assumed to provide adhesive sealing or a particular waterproof rating without confirmation from the manufacturer's technical documentation.
