Question by: Travis W on Apr 5, 2025, 3:22 PM
got a quarter inch tube here, is this the long nut that matches it or am i fixin to order the wrong thing
Answer by: Customer Support on Apr 7, 2025, 7:46 AM
The key callouts are right in the size: it’s made for 0.25 inch tube OD and it uses a 7/16-20 thread long flare nut, so it matches a quarter inch tube setup that needs that specific thread.
Question by: Ralph A on Dec 2, 2025, 10:37 AM
Will this nut work with standard brass tubing, or is it only for specific Aeroquip stuff?
Answer by: Customer Support on Dec 3, 2025, 11:44 AM
This long flare nut is designed for use with 0.25 inch OD tubing. As long as your brass tubing is that size, you should be good to go.
