Key Features Dimensional stability Uniformity and long-term strength Higher burst pressure Greater tensile strength DMFit LLDPE tubing is manufactured using an advanced grade of low-density polyethylene, offering superior environmental stress cracking resistance exceeding that of regular polyethylene tubing (as measured by ASTM D-1693 tests). This advanced grade of LLDPE protects against common stresses such as chemical exposure, ageing connections, and high-vibration loads. DMFit tubing is compliant with ANSI/NSF-51, 61, WRAS, and FDA requirements for food contact applications.
