Question by: Cody M on May 21, 2025, 7:52 PM
Hey, will this here adapter work with a 3/8" tube?
Answer by: Customer Support on May 23, 2025, 10:12 AM
this adapter's made for a 3/8" tube O.D., so you should be good to go.
Question by: Brett G on Apr 20, 2025, 7:41 PM
what size tube does this adapter work with, and will it fit standard 3/8 fittings I already got on my system?
Answer by: Customer Support on Apr 22, 2025, 7:49 AM
The 3/8 inch tube O.D. is what this one's built around, so if your existing connections are running 3/8 tube, you're in good shape. The A thread is 11/16-16 and the B thread is 9/16-18, so just make sure those thread sizes line up with what you've got on both ends before you order.

trying to swap out an old straight adapter, are the thread sizes on this one 11/16-16 on one end and 9/16-18 on the other?
Answer by: Customer Support on Oct 25, 2025, 7:27 AM
The A end is 11/16-16 thread and the B end is 9/16-18 thread. Both sides are listed with a 0.256 drill size.
