Polyethylene tubing is economical and suitable for many general purposes, including air, water and chemical transfer lines.  We manufacture our polyethylene tubing from raw materials that meet FDA requirements. LLDPE offers better flexibility and translucency compared to HDPE, and superior environmental stress cracking resistance compared to LDPE.  Our NSF 51/61 LLDPE tubing is certified to meet NSF 51 and NSF 61 requirements.
