Dual Layer Tubing
Optinova Dual Layer Tubing combines a high-performance fluoropolymer inner liner with a durable thermoplastic outer jacket, delivering an optimal balance of chemical resistance, mechanical strength, and cost efficiency. The inner layer provides excellent chemical inertness against a wide range of industrial fluids and gases, while the outer layer enhances durability and resistance to external environmental factors, including weak acids and bases.
This dual-layer construction offers a reliable and economical alternative to fully fluoropolymer tubing, without compromising on performance in demanding applications.

Dual Layer Tubing Product Sheet
Optinova Dual Layer Tubing operates optimally at -32°C to 82°C and complies with EPA SESDPROC-301-R1. Raw materials are top quality resins without PFOA surfactant and can meet your specific requirements.
Groundwater Sampling Tubing
The inner layer 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.
