Question by: Hugh M on Feb 9, 2026, 4:10 PM

Does this nut work with 15mm OD tube, or is it sized for something else? Got a WALPro fitting setup I'm trying to keep original parts on.

Answer by: Customer Support on Feb 11, 2026, 7:08 AM

Built specifically for 15 mm outside diameter tube in WALPro Series metric flareless assemblies. The M 22x1.5 thread is matched to WALPro fittings and sleeves, so you're keeping everything within the same system. As long as your existing setup uses WALPro components, this nut drops right in as a direct replacement.

Question by: Lance S on Aug 3, 2025, 2:18 PM

got a 15mm tube and need a nut for a metric flareless setup, is this the right one or am i off a size?

Answer by: Customer Support on Aug 5, 2025, 7:08 AM

For a 15.00 mm outside diameter tube, this union nut matches that tube size and it uses an M 22x1.5 thread. It is a WALPro Series nut (catalog C1KX14), so it is meant to pair with the corresponding WALPro fittings and sleeves.

Question by: Danny M on Aug 18, 2025, 6:47 PM

What size tubing does this nut fit? Just wanna make sure I'm getting the right thing.

Answer by: Customer Support on Aug 20, 2025, 4:32 PM
