Chemically inert connectors for reliable and contaminant-free fluid coupling
Specifications | Gallery | Related Products
The Ossila PTFE Union Connectors provide reliable, leak-free, and chemically inert fluidic coupling for high-performance laboratory architectures. Our Connectors are optimized for the rigid tubing systems common in gas diffusion electrode (GDE) flow cells, membrane electrode assembly (MEA) electrolyzers, and flow chemistry networks, ensuring smooth fluid transit without risking system contamination.
Fabricated entirely from premium polytetrafluoroethylene (PTFE), the metal-free construction preserves the integrity of your sensitive catalytic and electrochemical environments by eliminating the risk of trace metal or ionic leaching.
Our PTFE connectors are available in two configurations:
PTFE Straight (Equal) Connectors: Allows you to connect two fluid lines of the exact same diameter (e.g. 3 mm – 3 mm OD), ideal for extending fluid line length within the laboratory setup with minimum dead volume between identical tubing materials.
PTFE Reducing Connectors: For bridging two fluidic lines of different diameters. Most used to step down high-volume reagent or gas feed lines to match smaller entry ports on electrochemical cells or analytical instruments such as chromatography (e.g. GC-MS, ICP-MS), spectroscopy, or inline sensor set ups.
