Custom adapters
Compression to JIC adapters, machined to order
One machined part that connects compression tube to JIC 37° (AN) in the exact sizes you need, instead of a stack of off the shelf adapters. Pick the shape, material and finish, see the price as you go, and get it in 2 weeks.
Common sizes
Straight adapters in 316/316l stainless, priced each at 10 pieces. Any size is available on either end, and you can change the shape, length, bore and material in the builder.

About Compression
Double ferrule compression fittings for instrument and process tube, sized by tube outside diameter. Unions, elbows, tees, bulkheads and male connectors are the same bodies as other Specport parts, with compression ports on the ends.
Double ferrule compression, tube OD. Seals by: front and back ferrule bite on the tube.
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.
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 Compression to JIC adapter rated for?
It depends on the size and material. In 316/316l stainless, the common sizes on this page are rated from 1,000 to 5,000 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 Compression to JIC 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.
