TECH TIP

Because of their dead volume and the risk of thread leaks, pipe fittings are a poor choice for trrace gas analysis. Thread sealants, particularly PTFE tape, cannot boost their performance to adequate levels. For trace gas applications, choose Valco zero dead volume fittings with gold-plated stainless ferrules.
