Brother HSe-251E is a heat shrink tube cassette for professional cable and wire identification. It produces black print on a white 21.0 mm heat shrink tube and contains 1.5 metres of printable material for clear and permanent cable marking.
The non-adhesive tube is printed before being placed over the cable and shrunk into position using a heat gun. Brother specifies a 3:1 shrink ratio and recommends HSe-251E for cables with an outside diameter of 4.2 to 13.5 mm.

Brother HSe-251E is a Brother heat shrink tube cassette designed for professional identification of cables, wires and electrical connections. It produces black print on a white heat shrink tube, providing clear and easy-to-read identification for electrical, networking, industrial and technical installations.
The cassette contains 1.5 metres of heat shrink tube with a width of 21.0 mm. Brother recommends this size for cables with an outside diameter between 4.2 and 13.5 mm.
HSe-251E is specifically designed for identifying cables and wires rather than for conventional flat-surface labelling. The printable tube is placed around the cable and shrunk into position, creating a neat identification solution without the need for an adhesive backing.
It can be used for cable numbers, circuit references, equipment identification, connection points, technical codes and other information required for installation, maintenance and troubleshooting.
The black on white colour combination provides strong contrast, helping printed information remain clearly visible in technical environments. This makes the HSe-251E particularly useful in control cabinets, electrical panels, network installations, machinery and other areas where multiple cables need to be identified quickly.
The Brother HSe-251E requires a P-touch label printer that supports 21 mm HSe heat shrink tube cassettes. Compatible models available from SignProduction include the Brother PT-E560BTSP Professional Label Printer and the Brother PT-P900Wc High-Speed Wireless Label Printer.
The PT-E560BTSP is particularly suited to electricians, installers and on-site cable identification, while the PT-P900Wc provides a desktop solution for workplaces where professional labels and cable identification materials are produced from a computer or networked environment.
Please check compatibility before purchasing if you use another Brother P-touch model. Some Brother printers support HSe heat shrink tubing but are limited to narrower cassette widths and therefore cannot use the 21 mm HSe-251E.
The cassette contains 1.5 metres of 21.0 mm heat shrink tube. The wider format provides sufficient space for clearly readable identification and is suitable for larger cable diameters than narrower HSe cassette sizes.
Brother recommends HSe-251E for cables with an outside diameter from 4.2 to 13.5 mm. Measure the outside diameter of the cable before selecting the heat shrink tube to ensure that the chosen size is suitable.
Brother specifies a 3:1 shrink ratio for the HSe heat shrink tube. After printing, the tube is positioned over the cable and heated so that it contracts securely around it.
This allows the tube to conform closely to the cable while keeping the printed identification visible and securely positioned.
HSe-251E is non-adhesive. Unlike conventional label tape, it is supplied as a printable tube that is mechanically secured around the cable through heat shrinking rather than adhesive.
The tube should therefore be placed over the cable before installing a connector or termination that would prevent it from being passed over the end.
The Brother HSe-251E can be used for professional cable identification across a wide range of technical environments, including electrical installations, control cabinets, network infrastructure, industrial equipment, automation systems, telecommunications and equipment maintenance.
Its high-contrast black print and white tube make it particularly useful where clear cable identification is important for installation, servicing and troubleshooting.
Print the required information using a compatible Brother P-touch label printer, cut the tube to the required length and position it over the cable. Apply heat evenly with a suitable heat gun until the tube has contracted securely around the cable.
Always follow the operating instructions for both the Brother label printer and the heat source being used. When working with electrical installations, ensure that appropriate electrical safety procedures are followed.
