Tubing, Gas Tight, Polymeric 1/8'' OD x 1.65 mm ID. 1 Meter supplied in continuous length. ARE-Applied Research brand. 1EA.
Additional Information:
ARE-Applied Research Gas Tight Tubing is a dual-layer polymeric tubing system designed specifically for the transport of degassed solvents, purified water, and other laboratory fluids where minimizing gas permeation is important. Unlike conventional single-wall tubing, this design combines the chemical purity and inertness of FEP (fluorinated ethylene propylene) tubing with a non-porous PVDF (polyvinylidene fluoride) outer layer that helps prevent gas exchange through the tubing wall.
49811-01 consists of an FEP inner liner fused to a PVDF outer tubing layer, supplied as a continuous 1-meter length with a 1.65 mm internal diameter and 1/8 inch outer diameter. The FEP inner surface provides excellent chemical resistance and high purity fluid contact, while the PVDF outer layer provides an additional barrier against oxygen ingress and solvent outgassing. This construction makes the tubing particularly suitable for transporting degassed mobile phases and other oxygen-sensitive laboratory solutions.
To maintain a gas-tight connection at tubing interfaces, Kel-F inserts are used inside the FEP tubing bore. When combined with compatible polypropylene ferrules and flange-free low-pressure nuts, the system forms a reliable, leak-free, gas-tight fluid path for laboratory and chromatography applications.
