VICI Valco’s new dual-layer, color-coded PEEK tubing eliminates the concern that acritical sample stream could be contaminated by pigments used to colorcode the tubing. It looks like any other color-coded tubing at firstglance, but a closer look reveals that the pigmented layer surrounds aseparate but integrally-bonded inner layer of natural PEEK. Thepressure performance is equivalent to single-layer tubing. The 1/16″ OD tubingis available in OEM quantities with any ID specified, from .002″ to.030″. Standard ID sizes and colors are:  .005″ Red; .007″ Yellow;.010″ Blue; .020″ Orange; .030″ Green. The ID tolerance of +/- .001″ isequivalent to or better than that of tubing typically sold as premiumgrade. The tubing is available in a range of colors, striped orsolid. All colorants used in the manufacture of the tubing areRoHS-compliant (Restriction of Hazardous Substances).
