Product Questions & Answers (1)

Question by: Hubert C on Jan 4, 2026, 1:36 PM
Part number 1700-12-12, is that the same thing as NB6840-12-12? Trying to cross reference what we got on our last order.
Answer by: Customer Support on Jan 6, 2026, 7:03 AM
Same part, different number. NB6840-12-12 is an alternate part number for the 1700-12-12, and BR-1700-12-12 is another one you might run across. All three refer to this Brennan Industries straight fitting, so if your paperwork shows any of those, you're looking at the right piece.
