Why Choose the Partex HSMB191BLACK 2:1 Black Heat Shrink Tubing?
The Partex HSMB191BLACK is a professional 2:1 black heat shrink tubing product designed for electrical insulation, cable protection, wire bundling and general cable management. Manufactured by Partex, a specialist in cable marking and identification solutions, this heat shrink tubing provides a practical way to protect electrical conductors, insulated connections and cable assemblies while creating neat, organised wiring installations.
Featuring a nominal supplied diameter of 19.1 mm and a nominal recovered diameter of 9.5 mm, the HSMB191BLACK is suitable for appropriately sized electrical cables, insulated joints, cable bundles and electrical components. Its 2:1 shrink ratio allows the tubing to contract to approximately half its original diameter when correctly heated, creating a close-fitting protective sleeve around compatible cables and connections.
Supplied in a convenient 5 m pack with a practical black finish, the Partex HSMB191BLACK is ideal for electrical control panels, industrial automation, machinery wiring, cable harness manufacturing and general electrical maintenance. Its larger diameter makes it particularly useful for protecting cable assemblies and insulated connections that require more coverage than smaller heat shrink tubing sizes.

Reliable Insulation and Protection for Larger Cable Assemblies
Heat shrink tubing provides a convenient method of protecting electrical cables, insulated connections and wiring assemblies. The Partex HSMB191BLACK features a 2:1 shrink ratio, allowing its nominal diameter to reduce from 19.1 mm to approximately 9.5 mm when heated under appropriate conditions.
The larger supplied diameter makes this tubing particularly useful where a protective sleeve must pass over a cable joint, insulated connector or suitably sized bundle of conductors before shrinking. Once heated, the tubing contracts around the underlying surface to provide a neat protective covering.
Its black finish offers a discreet, consistent appearance that is well suited to industrial machinery, electrical cabinets and cable harnesses. Black heat shrink tubing is also useful where colour-coded conductor identification is not required and the priority is a uniform protective sleeve. It should not be relied upon to identify a particular conductor function unless the relevant installation documentation specifies that identification method.
When correctly selected and installed, the tubing helps provide supplementary insulation and protection against abrasion and general mechanical wear. It can also improve the appearance of wiring assemblies by covering suitable insulated connections and sections of cable sleeving. The tubing does not replace correctly rated primary conductor insulation or other required electrical safety measures.
For effective installation, select tubing with a supplied diameter large enough to pass over the widest part of the cable or component and a recovered diameter small enough to grip the intended surface. Cut the tubing to the required length, position it correctly and apply controlled, even heat using a suitable heat gun. Always follow the manufacturer's recommended installation conditions and avoid overheating adjacent components.
The HSMB191BLACK is intended for applications where a standard heat shrink sleeve is appropriate. Do not assume that it provides an adhesive-lined seal, waterproof joint or specified environmental resistance unless those properties are confirmed in the manufacturer's technical documentation.
