Alumaseal Ferrules Aluminum construction—will not crack or fragment. No retightening required after temperature cycles—excellent for GC-MS. Eliminate out-gassing and make leak-tight seals for less detector noise. Unique two-piece design permanently locks on fused silica tubing without causing breakage. Will not stick in fittings, unlike Vespel or graphite ferrules. Stable to 550 °C. Use with any 1/16" compression-type fitting. View Product Information
Graphite Ferrules for SeCure "Y" Connectors Preconditioned to minimize out-gassing. High-purity, high-density graphite. Stable to 450 °C. No binders that can off-gas or adsorb analytes. Smooth surface and clean edges. View Product Information
Graphite Ferrules for Vu2 Union Connectors High-purity, high-density graphite. Stable to 450 °C. No binders that can off-gas or adsorb analytes. Smooth surface and clean edges. View Product Information
