Product Questions & Answers (2)

Question by: Johnny C on Nov 17, 2025, 5:49 PM
got a 12mm metric steel flareless line, is this the right nut for it or am i off a size
Answer by: Customer Support on Nov 19, 2025, 6:21 AM
Fit comes down to two numbers on this union nut: it is made for 12 mm tube O.D. and it has an M 18x1.5 thread. If your WALpro metric steel flareless fitting uses those same sizes, this nut matches up.
Question by: Dwight C on Oct 24, 2025, 5:08 PM
Running a hydraulic line that needs to handle some real pressure. This nut rated for that kind of duty, or is it more of a light-duty piece?
Answer by: Customer Support on Oct 26, 2025, 10:28 AM
Four hundred bar is the maximum operating pressure on this fitting, which puts it solidly in heavy-duty territory for most industrial hydraulic work. The WALpro series actually carries a pressure rating that varies from 160 to 630 bar depending on the configuration, so this nut is built to handle serious system demands, not light service.
