Optinova’s Groundwater Sampling Tubing is a part of our Dual Layer Tubing solutions portfolio. The inner layer of Groundwater Sampling Tubing is made from premium FEP to comply with FDA21 CFR 177.1550 and NSF51. High quality resin allows the liner to be unaffected by most chemicals and the jacket is mechanically enhanced.

Key advantages:

  • Multi-layer construction
  • Good chemical resistance at inner liner
  • Physical toughness of outer jacket
  • Cost efficient solution due to unique jacketing process
  • No plasticizer used (no fluid leaching)
  • Ideal for VOC testing in groundwater
  • Complies with EPA SESDPROC-301-R1f experience


  • Inert FEP ensures the purity of the water sample and outer jacket made of LDPE supports the structure but keeps it flexible.
  • More cost-effective than full FEP tubing and can be supplied with additional armor over the LDPE to prevent external damage

Our tubing is available in all standard sizes between ID 1,6 mm (1/8″) and 12,7 mm (1/2″), however custom dimensions can be made upon request. While our production lengths are standard, we can also produce long continuous length to meet your requirements.
