About JIC
37° flare fitting that seals metal to metal on the flare seat. It shares the seat angle and threads with AN fittings, so a -6 JIC mates with a -6 AN. The most common hydraulic hose end in North America and the standard for motorsport fuel lines.
SAE J514. Seals by: 37° flare metal seat.
About Metric
Metric straight thread ports, sealed with an O ring stud or a sealing washer. Used on European and Asian hydraulics, automotive sensors and engine plumbing.
ISO 261, ISO 6149. Seals by: o ring stud or sealing washer.
One part, fewer leaks
A single machined adapter replaces a stack of two or three, so there are fewer joints to leak and the run is shorter and lighter.
Any shape
Straight, 45°, 90°, street 90, tee, Y, cross or a manifold with up to 8 outlets. Stainless, steel, brass, aluminum or engineering plastics.
Checked before it ships
Threads are checked with go and no-go gauges and every order ships with a certificate of conformance. Pressure test reports on request.
Questions
What pressure is a JIC to Metric adapter rated for?
It depends on the size and material. In 303 stainless, the common sizes on this page are rated from 2,370 to 4,750 psi, set by the lower rated end. The builder shows the exact rating for your part, including a wall thickness check.
Can I get a JIC to Metric adapter as an elbow or tee?
Yes. Choose straight, 45°, 90°, street 90, tee, cross or a manifold, then set the length, bore, material and finish. The price and pressure rating update as you design.
How many do I have to order?
There is no minimum. Single parts start at $120, pairs at $55 each, and the price per part drops as quantity goes up.
How fast will it ship?
Standard orders ship in 2 weeks. 1 week and 3 day delivery are available. Every thread is gauged, and every order ships with a certificate of conformance.
Need a size or shape not listed?
Every combination of 24 standards is available in the builder.
