Question by: Phil M on Jul 2, 2025, 10:03 AM
trying to replace a lost nut on a JIC line, is 1290-12S the right one for 3/4 tube?
Answer by: Customer Support on Jul 4, 2025, 6:09 AM
For a 0.75 inch OD tube, the 1290-12S is the matching 1290 Series JIC 37 degree flared nut, so it fits that tube size and flare style.
Question by: Gary C on May 22, 2025, 4:41 PM
Got a 3/4 inch OD tube line that needs a new flare nut, this the right part for that?
Answer by: Customer Support on May 23, 2025, 5:49 PM
For 3/4 inch OD tube with a JIC 37 degree flare connection, this is the correct nut. It's part of the Eaton Aeroquip 1290 Series and carries the catalog number C1AJ73. The A dimension runs 1.02 inches and the B dimension is 1.25 inches, so double-check those measurements against your existing hardware before ordering. It's a steel fitting, so it should hold up well in standard hydraulic line applications.
Question by: Bobby C on Apr 24, 2025, 9:07 AM
What size tubing does this nut fit? Just want to make sure I'm ordering the right thing.
Answer by: Customer Support on Apr 25, 2025, 2:44 PM
This flare nut is made for use with 0.75 inch OD (Outside Diameter) tubing.
