5001-3739, Agilent Support Seal Assembly for HPLC

The Agilent HPLC Autosampler Metering-Head Support Seal Assembly is a mechanical replacement part for compatible liquid chromatography autosampler measuring-head hardware. The support component positions the metering seal within the fluid-handling assembly and contributes to reliable operation when the correct seal and piston are installed. Wear, damage or incorrect seating in this area can affect the integrity of the metering system, making accurate component selection important during maintenance. Use the specific autosampler service documentation to confirm the required measuring-head configuration and the surrounding replacement parts. Before opening the fluid path, depressurize and isolate the instrument, then inspect the piston, seal, support surfaces and fittings for contamination or visible damage. Reassemble with the appropriate tools and perform the recommended leak and metering checks before analytical operation. This support assembly is not an HPLC analytical column, mobile-phase filter or complete pump head. Compatibility should be matched to the supported autosampler metering-head design, not inferred from the broad HPLC category.
