Perkin Elmer, B0198110, O-Ring for Needle Seal Assembly, 10/pk

The PerkinElmer TurboMatrix headspace needle seal O-rings are replacement elastomer seals for the needle-seal assembly in compatible TurboMatrix headspace samplers. The needle-seal interface must maintain a controlled gas path during sample pressurization and transfer, making its condition important for consistent vapor sampling. Worn or damaged O-rings may allow pressure losses, leaks or inconsistent headspace transfer conditions. The package contains ten O-rings for servicing the mating needle-seal assembly. These are the separate O-ring consumables rather than the needle-seal assembly itself, which is supplied under a different part identity and specifically does not include O-rings. During service, inspect the assembly surfaces for contamination or scratches and replace rings without stretching or cutting them. After reassembly, carry out the instrument's prescribed sealing and pressure checks before returning the sampler to analytical use. These components do not replace headspace needles, transfer lines or sample-vial septa.
