Collet covers prevent accidental removal or tampering with tubing. Tubing can be inserted with the collet cover already attached to the fittings or the collet can slide into position afterwards. The collet is easily removed when required and they are available in gray (S as suffix) yellow (Y), black (E), red (R), blue (B), or green (G). Collets can be installed by hand but we also offer a tool for easy removal.
