Product Questions & Answers (3)

Question by: Earl B on Mar 18, 2026, 10:11 AM
what industries is this adapter actually built for? got a pulp mill application and tryin to figure out if it'd hold up
Answer by: Customer Support on Mar 20, 2026, 7:06 AM
Pulp and paper is one of the listed applications for this adapter, along with marine and military use, chemical processing, food and beverage, and offshore drilling. Steel construction and the FF2031T series reputation for durability make it a reasonable fit for that kind of demanding environment.
Question by: Daryl H on Mar 12, 2026, 5:57 PM
Will this adapter work for connecting a SAE O-Ring to a NPT setup?
Answer by: Customer Support on Mar 14, 2026, 6:21 AM
That's what it's for. It's made to connect an 11/16-14 Male SAE O-Ring Face Seal to a 1/2-14 Male NPT thread.
Question by: Jean B on Sep 30, 2025, 1:16 PM
got a port that’s 11/16-14 ORFS on one side and i need to tie into 1/2-14 NPT, is this the right straight adapter for that?
Answer by: Customer Support on Oct 1, 2025, 3:05 PM
Connection-wise, this adapter is made exactly for that matchup: 11/16-14 male SAE O-ring face seal on one end to 1/2-14 male NPT on the other, in a straight configuration.
