    Has anyone had issues with leaky Viper lines on a Thermo LC? It seems anytime I have to mess with one, it takes me a few tries to get it attached to where it won’t leak. Is this common or do I have worn out fittings (or some kind of user error)?

    We used to have issues with viper and nanoviper lines but now we use a torque screwdriver (H4DETSD) with a hexagonal adaptor bit with a cutout for the line to tighten the lines to ~30 cNm and ~20 cNm for metal viper and glass nanoviper connections respectively. We also do a near fully connected leak check with a pre-detector plug (closed system). This has resolved all viper tightening leak issues for us.
