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 Injector
Fuel injector cups and spigots bored and honed to common injector O ring diameters. Used for fuel rails, injector adapters and spacers.
Common injector O ring bores. Seals by: injector o ring in honed bore.
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 Injector adapter rated for?
It depends on the size and material. In 6061-t6 aluminum, the common sizes on this page are rated from 750 to 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 Injector 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.
