thread size on this one is M 14x1.5 right? trying to match up a replacement nut for an 8mm line and want to make sure before i order
Answer by: Customer Support on Nov 17, 2025, 6:24 AM
Correct on both counts. The thread is M 14x1.5 and it's sized for an 8.00 mm tube outer diameter, so if that matches what you're pulling off the line, this is the right nut. It's part of the WALpro Series from Eaton and built to current DIN standards, so dimensional fit should be consistent with other DIN-compliant flareless fittings in that size range.

got a WALpro flareless setup with 8mm tube, is this the right nut for it or am i gonna be fighting the threads

Match it up by the two fit points given: it’s a WALpro Series union nut for 8.00 mm tube O.D., and the thread size is M 14x1.5. If your existing nut is M14x1.5 and you are on 8 mm tube, this is the correct replacement style.
