Brady M4-125-075-342 B-342 Heat-Shrink Sleeve, Black on White, 3.18 mm dia x 19.05 mm

Brady PermaSleeve B-342 is a flame-retardant heat-shrink polyolefin wire marking sleeve for Brady M4 and M5 cartridge printers. This listing has 15 cartridges: eight die-cut cartridges of 80 sleeves each (M4 sleeves 19.05 mm wide and M5 sleeves 25.4 mm wide, each in four diameters from 3.18 to 9.53 mm), and seven M4C continuous cartridges of 2.13 m (7 ft) in white or yellow (manufacturer-stated).

Brady lists the sleeves for the BMP41, BMP51, BMP53, M410, M510 and M511 printers (M4 and M4C cartridges) and the BMP51, BMP53, M510 and M511 (M5 cartridges). Brady's page titles describe them as supplied with ribbon, and its specification table gives no separate ribbon part number (manufacturer-stated). We also stock the Brady M511 label printer.

B-342 shrinks 3:1, has a matte finish and a service temperature of -55 to 135 °C (-67 to 275 °F). Brady describes it as a self-extinguishing polyolefin that resists extreme temperatures, UV light, chemicals, fuel and oil, calls it military grade, and says it is designed for military, aerospace, defence and transit wire marking (manufacturer-stated). Brady lists UL Recognized to UL 224, RoHS compliant to 2011/65/EU, SAE AS23053/5 (Class 4) and AS-5942, SAE AS-81531 and MIL-STD-202 (manufacturer-stated). Brady's product pages are written for the US market, and standards or approvals they list are North American, so ask us if an approval matters for your job.

Common specifications

Which sleeve for which wire

Key specifications

Selecting the right option

Choose the sleeve by the diameter of the wire, not the cable's rating: 3.18 mm sleeves fit 1.17 to 2.79 mm wire (22 to 16 AWG), 4.75 mm fit 1.57 to 3.81 mm (20 to 10 AWG), 6.35 mm fit 2.39 to 5.46 mm (16 to 8 AWG) and 9.53 mm fit 3.18 to 8.13 mm (12 to 4 AWG) (manufacturer-stated). Then choose the cartridge: M4 cartridges (19.05 mm wide) and M5 cartridges (25.4 mm wide) hold 80 die-cut sleeves, and M4C cartridges are continuous so you cut each sleeve to length. Check that your printer is on the list above. For sleeves for the B33 printers see the B-342 single-sided heat-shrink sleeves for B33 printers, B-342 double-sided heat-shrink sleeves for B33 printers and B-345 PVDF high-temperature sleeves for B33 printers.
