• Brightly colored knobs and ChromTRAC mapping provide a code for fluid
  connections
• Easily track inlets and outlets of valves, columns, and detectors
• Dyed colors stay out of fluid stream

Rheodyne's innovative ChromTRAC color-coding system is the industry standard for simplifying your fluid connections. Seven ChromTRAC colors clearly identify tubing lines and visually distinguish different components in the same system. Combined with unique ChromTRAC mapped valves, the colored knobs on RheFlex Fittings allow you to coordinate port to fittings to system component without confusion. The diagram below shows an example of a ChromTRAC mapped valve. The mapping indicates the color standard of the ChromTRAC color-coded RheFlex fitting to be used in each port.

On RheFlex PEEK Fittings, ChromTRAC knobs snap directly on nuts to make fingertightening easy. ChromTRAC knobs can easily fit over stainless steel nuts for visual flow path identification. These bright colors remain outside the fluid stream, avoiding dye leaching into your sample.

ChromTRAC is available in a Fittings Identification Kit, a 20 pack of multi-colored knobs. The Fittings Identification Kit contains 20 ChromTRAC knobs in black, white, green, gray, yellow, red, and blue. These replaceable ChromTRAC knobs are compatible with RheFlex One-Piece; 10-32, 1/16"; RheFlex PEEK; all 1/4-28 RheFlex TF; and all 1/4-28 RheFlex Flangeless Fittings.

RheFlex fittings have the ChromTRAC knob option, which can be specified at the time of ordering by indicating the ChromTRAC two letter suffix for the color choice. ChromTRAC Suffix Codes below lists the color codes. "MC" refers to "multi-color" which includes two each of blue, green, gray, red, and yellow.
