Question by: Marvin S on Dec 28, 2025, 5:56 PM
got a line that steps down from 6mm tube to 4mm, is the DUOLOK B FC 06X04 the right connector for that?
Answer by: Customer Support on Dec 30, 2025, 6:13 AM
For stepping between those two tube sizes, it matches that exact 6 mm to 4 mm configuration. It is a Duolok tube fitting connector meant for compact instrumentation and process lines where you need a secure connection between different tube sizes.
Question by: Ricky H on Aug 7, 2025, 9:06 PM
What size tubing does this connector work with?
Answer by: Customer Support on Aug 9, 2025, 3:53 PM
It adapts a 6mm tube down to a 4mm tube. Handy if you're needing to connect different size lines together.
