Question by: Kirk W on Oct 30, 2025, 7:48 PM
got two hoses with 3/4-16 jic ends, i just need a straight coupler between em. is this the right piece?
Answer by: Customer Support on Nov 1, 2025, 8:10 AM
For joining two 3/4-16 Male JIC 37 degree flare ends in a straight run, this adapter is the right style. It is a straight union with 3/4-16 male JIC 37 degree flare on both sides, so it seals metal to metal at each flare seat.
Question by: Rhonda D on Jun 9, 2025, 9:40 AM
So this thing is made of stainless steel? Just makin' sure it won't rust on me.
Answer by: Customer Support on Jun 11, 2025, 8:25 AM
That's right, this adapter is constructed from 316 stainless steel, which offers excellent resistance to corrosion, especially against chlorides. It's a good choice where regular steel just won't hold up.
Question by: Freddie B on Feb 25, 2026, 9:52 AM
got a line that needs a male JIC on both ends joined up, this the right piece for that?
Answer by: Customer Support on Feb 26, 2026, 4:03 PM
That's what this adapter is built for. It connects two 3/4-16 male JIC 37-degree flare fittings in a straight run, acting as a union between them. Both ends seat with a metal-to-metal flare contact, so you get a solid seal without needing any additional sealing compound. Works with 1/2-inch OD tubing and measures 1.62 inches overall, so it fits into standard JIC hydraulic line setups without any reworking.
