Question by: Daryl F on Jan 21, 2026, 9:26 PM
Does this female pin lug coupling work with standard male pin lug fittings, or does it need something specific to Kuriyama?
Answer by: Customer Support on Jan 23, 2026, 10:24 AM
Female pin lug connections follow a standardized interface, so this 2-1/2 inch coupling will engage and lock with compatible male pin lug fittings at that same size. Kuriyama builds to that common standard, which is part of why pin lug setups are so widely used in industrial fluid transfer. As long as your male fitting matches the 2-1/2 inch pin lug spec, you should get a solid connection.
