Tempered brass construction makes the difference between secure crimp connections and frustrating failures. These tubes withstand the compression force from crimping pliers without splitting or cracking, maintaining a tight grip on your beading wire. The 1.8mm diameter pairs specifically with Beadalon stringing wire, proper sizing prevents both loose connections that slip and oversized crimps that look clunky against your beadwork.

Consistent dimensions across every tube mean reliable results whether you're finishing your first bracelet or your hundredth necklace. The tempering process hardens the brass just enough to hold firm under pressure while retaining enough give to round smoothly with crimping pliers. Silver plated and gold color finishes blend seamlessly with your findings and design aesthetic.

Size #2 tubes handle medium-weight stringing projects: standard bracelets, necklaces, and multi-strand designs where clean, professional closures matter. Crimp them flat for a low-profile finish, or round them for a more polished appearance. Either way, properly crimped tubes create permanent connections that won't pull apart during normal wear.
