High-Density Polyethylene (HDPE) tubing is the environmental industry’s preferred choice for rigorous groundwater sampling and deep monitoring well applications. Designed to handle demanding field conditions, HDPE offers superior structural rigidity, significantly reduced stretch, higher lift capabilities, and enhanced flow rates compared to standard Low-Density Polyethylene (LDPE). Its natural resistance to volatile organic compounds (VOCs) and naturally occurring soil gasses ensures sample integrity across complex environmental sites. Because of its high tensile strength and durable construction, HDPE has largely replaced costly Teflon as the economical industry standard for deep well sampling, micro-flow monitoring, and high-volume purging.
Ensuring accurate, cross-contamination-free field samples is critical on PFOA and PFOS sensitive monitoring sites. ECT Manufacturing’s high-density polyethylene tubing underwent independent laboratory testing to verify that it will not introduce detectable per- and polyfluoroalkyl substances (PFAS) into collected water samples. Screened using EPA Laboratory Method 537M, our HDPE tubing yielded non-detect results across all 40 tested PFAS compounds. This verified purity makes ECT’s HDPE tubing a reliable, compliant source for environmental consultants, hydrogeologists, and field technicians conducting sensitive groundwater investigation without risking sample degradation.
Available in a wide variety of inner and outer dimensions—ranging from .17" x 1/4" micro-flow tubing to 0.814" x 1" high-flow sizes—our HDPE product line is engineered for direct compatibility with leading field sampling equipment. Whether paired with Waterra micro-flow, standard, or high-flow foot valves, or utilized alongside Geoprobe bladder pumps, our tubing ensures a tight seal and reliable performance under vacuum or positive displacement pressure. Explore our selection of PFAS-tested HDPE tubing below to equip your next groundwater sampling project with field-proven reliability.
