Often, when we need to get fluids through a fitting, we turn to teflon tape for a tight seal with no leaks. It's important to know, however, that for CGA fittings, it's important NOT to use teflon tape, as the fittings are designed for a "dry fit" with metal-to-metal contact. We recently learned this as we began drawing gaseous nitrogen from the headspace of our liquid nitrogen tank. See file below for more information.
