Main Differences

When you compare SAE and JIC fittings, you see some big differences. The flare angle is easy to spot first. JIC flare fittings have a 37-degree angle. SAE flare fittings have a 45-degree angle. This change affects how the fittings seal and how much pressure they can take.

JIC fittings are best for high-pressure jobs. You find them in places like factories, airplanes, and military machines. SAE fittings are good for medium-pressure systems. You often see them in cars and smaller machines.

The material is also important. JIC flare fittings are made from steel or stainless steel. These metals are strong and can handle heat well. SAE flare fittings use brass, copper, or aluminum. These metals fight rust better but are not as strong.

Thread type matters too when you look at SAE and JIC fittings. JIC fittings use UNF threads. SAE fittings use NPT threads. You need to match the thread type to your system so you do not get leaks and your connection stays tight.

Always check the pressure rating before you pick flare fittings. JIC fittings can handle more pressure. SAE fittings work with less pressure. If you need a fitting for a tough job, JIC is the best choice. If your job is lighter, SAE should work fine.

Novafit is a leader in hydraulic fittings. You get certified products and careful inspections from them. Their focus on quality means you get fittings that last and work well for any job.

Key Differences

Flare Angle

The biggest difference is the flare angle. JIC fittings have a 37-degree flare. SAE fittings have a 45-degree flare. The angle changes how they connect and seal. Using the wrong angle can cause leaks. It can also make your system work badly. Always pick the right flare angle for your system.

Sealing

Sealing stops leaks and keeps your system safe. JIC fittings make a strong seal with metal touching metal. They use a 37-degree flare for this. Most times, you do not need O-rings or sealants. JIC fittings work well in high-pressure and shaking places. Some JIC fittings have an O-ring at the nose. This gives extra leak protection. SAE fittings have a 45-degree flare. They work best in lower-pressure systems. They do not seal as well as JIC fittings.

Tip: Pick JIC flare fittings for tough jobs where leaks are a big problem.

Thread Type

Thread type is important for connecting fittings. JIC fittings use UNF threads. These are common in North America and big machines. SAE fittings use NPT threads. These are used in plumbing and many other jobs. You cannot swap these thread types. Always check the thread type before you put in flare fittings.

Interchangeability

Compatibility Issues

You might think you can swap JIC and SAE hydraulic fittings. But you cannot do this. These fittings look almost the same, but they are different. JIC fittings have a 37-degree flare. SAE fittings have a 45-degree flare. This difference means they will not seal right if you mix them. You could get leaks and your system may not work well.

If you connect fittings with different thread types, you can hurt the threads. JIC fittings use UNF threads. SAE fittings use NPT threads. These threads do not fit together. If you try to force them, you can strip or crack the threads. Always check the flare angle and thread type before you connect fittings.

Tip: Use the same type of fitting in your hydraulic system. This helps stop leaks and keeps your equipment working well.

Risks

Mixing JIC and SAE fittings can cause big problems. You might see leaks where the fittings join. Leaks can make you lose hydraulic fluid. This can stop your system from working. Sometimes, leaks can be dangerous or break other parts.

Here are some risks if you mix the wrong fittings:

  • Leaks waste fluid and lower pressure
  • Damaged threads make repairs harder
  • More downtime from system failures
  • Higher costs from fixing things again and again
