Flame Retardant Polyethylene Tubing is a superior quality, flame retardant, stress crack resistant, exclusively compounded polyethylene tubing product for pneumatic instrument controls. Color-coding in up to seven different color stripes is available for instant, easy identification. Bright color stripes are extruded directly in the outside surface of the tubing and provide permanent color-coding that will not wear or fade. When color-coded, the combination of color stripes and printline numbering provides for up to 210 pneumatic circuit lines without duplicating a color stripe-number combination.
