  • Please don't use teflon or whatsoever in purge valve fittings, you got to avoid this material entering the system; the risk of entire LC system contamination is too high.

    What kind of purge valve is that? I don't see the PV O-rings P/N 5067-6595. I suggest you to change the gold seal cap assemby P/N 5067-4728, and to use teflon while the spare parts arrive; and better, to replace the entire purge valve, P/N G7111-60061.

    We use LC 1290/1260/1100 with these 2 purge valve in our lab.
