Partex HSMB127BLACK black 2:1 heat shrink tubing, supplied in an 8 m pack with a nominal diameter of 12.7 mm shrinking to 6.3 mm, designed for electrical insulation, cable protection and wiring management.
£13.90
The Partex HSMB127BLACK is a versatile 2:1 black heat shrink tubing designed for electrical insulation, cable protection and wire identification in industrial, commercial and electrical installation applications. Featuring a nominal diameter of 12.7 mm before shrinking and 6.3 mm after shrinking, this heat shrink sleeve provides a neat, close-fitting solution for protecting cables, conductors and electrical connections.
As part of the Partex HSMB heat shrink tubing range, the HSMB127BLACK offers a practical solution for cable management and electrical wiring protection. When suitable heat is applied, the tubing contracts around the underlying cable or component, helping protect against abrasion, mechanical wear and everyday handling. Its black finish provides a professional appearance for cable assemblies, electrical installations and industrial wiring systems.
Supplied in a convenient 8 m pack, the Partex HSMB127BLACK is ideal for electricians, electrical panel builders, maintenance engineers and industrial automation professionals. Its 2:1 shrink ratio and larger 12.7 mm supplied diameter make it particularly useful for insulating and protecting medium-sized cable bundles, electrical joints and wiring assemblies.
Heat shrink tubing such as the Partex HSMB127BLACK provides a convenient method of insulating electrical conductors, covering wire joints and protecting cable assemblies. By applying controlled heat, the tubing contracts around the cable or connection, forming a close-fitting sleeve that helps improve wiring organisation and reduce exposure to everyday mechanical wear.
The 2:1 shrink ratio allows the tubing to reduce from its nominal 12.7 mm supplied diameter to approximately 6.3 mm when fully recovered. For effective installation, the tubing should be large enough to pass over the widest section of the connection before heating and capable of shrinking securely around the smallest section. Its larger diameter makes it particularly useful for covering cable joints, insulating compatible connectors and protecting groups of electrical conductors.
