ECT Manufacturing’s 100% virgin FEP (Fluorinated Ethylene Propylene) Teflon® tubing is engineered specifically for demanding environmental monitoring, sub-slab soil vapor intrusion assessment, and groundwater sampling applications. Featuring an operational temperature threshold ranging from -100°F to 400°F and near-zero moisture absorption, this ultra-pure fluoropolymer tubing provides exceptional chemical resistance and low permeability when sampling volatile organic compounds (VOCs) or operating in harsh subsurface conditions. As a high-performance, non-leaching sampling line, virgin FEP tubing contains zero PFOA additives and fully complies with California DTSC standards for sub-slab vapor gas monitoring and environmental compliance field testing.
Designed to maintain high clarity and UV transmission without imparting taste, odor, or secondary cross-contaminants, our flexible FEP tubing serves as an ideal lead and lift line for groundwater pumps, well developers, and foot valve systems. Manufactured in standard inner and outer diameter (ID/OD) dimensions—including 1/8", 1/4", 3/8", 1/2", and 5/8" sizes—each roll meets strict ASTM D 2116 specifications to deliver maximum burst pressure strength and self-extinguishing flame resistance. Explore our complete selection of in-stock FEP Teflon® tubing below to equip your environmental field crews with industry-approved, laboratory-grade gas sampling lines.
