What size tube does this nut fit? Gotta make sure I'm ordering the right thing.

This flare nut is designed for a 1.25 inch outside diameter (OD) tube.

got a versil-flare assembly i'm trying to rebuild and need to know if this nut fits 1-1/4 inch OD tubing. that right?

Question by: Kirk W on Jul 25, 2025, 6:23 AM

that's the correct size. SKU 1290-20S is built specifically for 1.25 inch OD tube, so if your Versil-Flare assembly is running that tube size, this is the replacement nut you want. It's part of the Eaton Aeroquip 1290 Series spare parts lineup, so it'll drop right into that system.
