Question by: Rusty M on Oct 12, 2025, 12:10 PM
got a 1/4 inch OD tube line, is this the right flare nut for it?
Answer by: Customer Support on Oct 14, 2025, 6:40 AM
For a 0.25 inch outside diameter tube, this matches the size callout. It is a JIC 37 degree flared nut in the Aeroquip 1290 series.

Question by: Pete F on May 26, 2025, 8:49 PM
Will this nut fit a standard JIC flared fitting on a 1/4 inch OD tube? Just want to make sure before I order.
Answer by: Customer Support on May 28, 2025, 7:37 AM
This flare nut is specifically designed to work with 0.25 inch OD tubing in JIC 37-degree flare connections. It's an Aeroquip by Danfoss/Eaton 1290 series Versil-Flare nut, so it should be compatible with other fittings designed to meet that standard.
