Question by: Diane M on Jan 26, 2026, 1:53 PM
part number AL-A250, that the same as C1FX90, or are those two different parts?
Answer by: Customer Support on Jan 27, 2026, 9:48 PM
Same part, different number. AL-A250 is the Kuriyama supplier part number, and C1FX90 is an alternate part number for the same adapter. If you've been ordering under either one of those, you're looking at the same Kuriyama AL Coupling ADAP either way.
