Series E Instrument Grade PE Tubing
Parflex flexible polyethylene thermoplastic tubing is extruded from high molecular weight resin for increased dimensional stability, uniformity and long-term strength. Its resistance to environmental stress cracking greatly exceeds that of ordinary polyethylene tubing as measured by ASTM D-1693. (10% IGEPAL). Parflex polyethylene tubing is available in black as well as seven coding colours as recommended by the Instrument Society of America. Black (EB) tubing contains an ultra-violet inhibitor which is recommended for use in sunlit areas. Ingredients of natural and colour tubing (except black) listed below meet F.D.A. requirements for food contact applications. All tubing conforms to ASTM D-1248, Type I, Class A, Category 4, Grade ES. Parker Fast & Tite fittings or Parker Brass fittings are recommended for this type of Tubing. The suggested operating temperature -80F (-62C) to +150F (+66C).
