Question by: Kirk M on May 2, 2025, 12:20 PM
what's the thread size on the male end of this adapter? trying to figure out if it'll work with my existing 1" pipe fitting setup
Answer by: Customer Support on May 3, 2025, 9:23 PM
The male end runs a 1-11/2 NPT thread, which is a 1-inch nominal pipe thread at 11.5 threads per inch. If your existing fittings are standard 1" NPT, this will mate up correctly. The female end steps down to 3/4-14 NPT, so this is a reducing adapter going from the larger male connection to the smaller female port.
Question by: Bobby H on Aug 14, 2025, 7:39 AM
Will this here adapter work to connect a 1-11-1/2 male pipe to a 3/4-14 female pipe?
Answer by: Customer Support on Aug 16, 2025, 7:26 AM
Yes, sir, this steel adapter is made to join a 1-11-1/2 male NPT to a 3/4-14 female NPT pipe, straight as an arrow.
