PLEXCO® 2600 Instube®4 Pneumatic Tubing

Flame Retardant (FR) Polyethylene Tubing

Application: Performance Pipe PLEXCO® 2600 Instube®4 Flame Retardant Polyethylene Tubing is a superior quality, flame retardant, stress crack resistant, exclusively compounded polyethylene tubing product for use in pneumatic instrument control applications.

Marking:  PLEXCO® 2600 Instube®4 is marked with a white ink numbering system over the full length of the tubing. Bright color stripes are extruded directly into the outside surface of the tubing and provide permanent color-coding that will not wear or fade.

Identification:  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.

NOTICE – This table provides typical physical property information for the polyethylene natural resin used to manufacture PLEXCO® 2600 Instube®4 Pneumatic Tubing products. It is intended for comparing compounds and tubing. It is not a product specification, and it does not establish minimum or maximum values or manufacturing tolerances for compounds or tubing. Values obtained from tests of specimens taken from tubing can vary from these typical values. Performance Pipe has made every reasonable effort to ensure the accuracy of this information, but this table may not provide all necessary information, particularly with respect to special or unusual applications. This information may be changed from time to time without notice. Contact Performance Pipe to determine if you have the most recent edition.
