PTFE Solid Ferrule Use with #7 Ace-Thred
PTFE ferrules can substitute for the Ace-Thred o-ring to avoid any possibility of sample contamination. Additionally, the use of our pre-drilled ferrules will allow the use of a slightly smaller OD tube. For example, our 5029-45 PTFE bushing with a ferrule will allow the use of a 1/4in OD tube rather than the usual 7mm OD tube. Ferrules are also available in solid versions ready for a customized size hole.
