Question by: Bonnie C on Jan 3, 2026, 9:54 AM
trying to hook a 1/4-19 BSPP male port up to a 3/8-19 BSPP female swivel, is that what this adapter does?
Answer by: Customer Support on Jan 4, 2026, 8:25 PM
It steps between two BSPP thread sizes, going from 1/4-19 male BSPP on one side to a 3/8-19 female BSPP swivel on the other, in a straight adapter.
