Just wanna make sure, both ends are the same size, right?
Answer by: Customer Support on May 11, 2025, 5:12 PM
That's correct. This is a straight adapter, meaning both ends share the same 9/16-18 size and male JIC SAE 37-degree flare thread type, as specified by SAE J514.
Question by: Ricky W on Jan 31, 2026, 9:11 AM
got a hose with 9/16-18 JIC ends, is this just a straight male-to-male coupler for that?
Answer by: Customer Support on Feb 1, 2026, 2:32 PM
For joining two JIC flare connections straight through, it uses male JIC SAE 37 degree flare threads on both ends, and both sides are 9/16-18 per SAE J514.
Question by: Patty W on Dec 20, 2025, 7:00 AM
Got a hydraulic line running 9/16-18 JIC fittings on both ends and need to union them together. This the right part for that?
Answer by: Customer Support on Dec 22, 2025, 6:57 AM
That's what this fitting is built for. Both ends are male JIC with a 37-degree flare and a 9/16-18 thread, so it'll bridge two female JIC connections on the same line. Just make sure both your hose ends or port connections are female JIC to match up correctly.
