    Piston seals wear out over time and Restek is your best option for economical replacements. Choose our graphite-filled PTFE seals, which are best for organic solvents.

  • Seals And Pistons

    Agilent Technologies

    Pump seals should be replaced when there are leaks on the bottom of the pump head, when retention times are inconsistent, or when the pressure ripple is unstable. Each time the seals are replaced, the pistons (plungers) should be examined for scratches. Scratched pistons will cause small…

  • ASI Piston Seals for Agilent HPLC Systems

    Restek

    Over time the piston seal in every HPLC system becomes worn and must be replaced. Our piston seals are constructed of PTFE material with an additive that reduces their tendency to "cold flow" and improves their wear characteristics. PTFE seals are more resistant to any HPLC solvent…
