How to choose the right Heat Shrink Tube for Brother PT-18RZ

Common user questions and simple fixes (PT-18RZ)

Working with heat shrink media is straightforward, but a few recurring situations come up. Here’s what we recommend:

• “The tube doesn’t shrink evenly.” Use steady, moderate heat and rotate the cable for uniform shrinking. Avoid overheating one spot.
• “The text is too small or cramped.” Choose a wider tube (e.g., 9–12 mm) for longer identifiers or multi-line layouts.
• “I’m not sure which cartridge fits my printer.” Look for the HSe symbol and the code (e.g., HSe-211, HSe-231, HSe-621)—these are dedicated heat shrink tube series for Brother P-touch models like the Brother PT-18RZ.
