Product Questions & Answers (3)

Question by: Brenda R on Apr 18, 2025, 8:28 PM
What size tubing does this union nut fit? Gotta make sure I'm gettin' the right one.
Answer by: Customer Support on Apr 20, 2025, 7:45 PM
This union nut is designed for a 10 mm outer diameter tube.
Question by: Phil C on Oct 27, 2025, 3:25 PM
fitting says it goes up to 500 bar but I see mentions of 160 to 630 bar depending on series, which one actually applies here?
Answer by: Customer Support on Oct 29, 2025, 11:55 AM
The 500 bar figure is the maximum operating pressure for this specific fitting. The broader 160 to 630 bar range covers the full Series S classification, which includes multiple sizes and configurations. Where this particular nut lands within that range depends on the application setup, but 500 bar is the rated ceiling for this part. The 4:1 safety factor applies across the series, so that holds here as well.
Question by: Roy W on Mar 24, 2025, 9:20 AM
trying to replace a union nut on a metric flareless fitting. is this one the WALpro nut for 10mm tube and M16x1.5 threads?
Answer by: Customer Support on Mar 26, 2025, 7:17 AM
It matches a 10 mm tube outer diameter and an M 16x1.5 thread, and it is called out as a WALpro Series union nut for metric steel flareless fittings.
