Used of Where Could 37° Fittings

Pressure Ratin

Pressure ratings differ with fitting material, manufacturer, or temperature. Be aware of your specific fitting manufacturer‘s guidelines and follow them for pressure and temperature usage.

Fitting Material

JIC fittings are available in many different materials including brass, steel, stainless steel, aluminum, and titanium. Some fitting materials may be more or less compatible with other fittings or the media flowing in your system. So be sure and identify compatibility before deciding on a material.

Media Density

Since JIC uses a metal-on-metal seal, it is not ideal for lighter gasses. Media of this type may be able to seep through the microscopic imperfections on the metallic surfaces. In this case, a fitting type that uses a rubber or other soft material may be desirable.

FAQ

 

Q: What are JIC fittings used for?

A: JIC fittings are commonly used in high-pressure hydraulic applications due to their 37-degree flare design, which offers a robust mechanical seal.

Q: How do NPT differ from JIC?

A: NPT hydraulic fittings have tapered threads and usually require a thread sealant, whereas JIC fittings have a 37-degree flare and generally do not require additional sealants.

Q: Can JIC and NPT be interchanged?

A: While there are adaptors that can connect JIC to NPT, it's generally not advisable due to the risks involved, such as thread mismatch and varying pressure resistance.

Q: What tools are required for installing JIC and NPT fitting?

A: An adjustable wrench is essential for both, and thread sealant is usually required for NPT fitting.

Q: How often should I inspect my hydraulic fittings?

A: Regular inspection intervals depend on the system's usage and the manufacturer's guidelines, but a monthly check is generally a good practice.

Q: When should I replace my hydraulic fittings?

A: Replace fittings if you notice signs of wear, or corrosion, or if there are performance issues like reduced pressure or fluid leaks.

Q: Are JIC fittings reusable?

A: Yes, one of the advantages of JIC fittings is their reusability, offering long-term value.

Q: What safety precautions should I take when installing fittings?

A: Always wear safety goggles and gloves, and ensure the hydraulic system is depressurized before starting any installation or maintenance work.

Q: Which is more cost-effective: JIC or NPT?

A: NPT pipe fittings are generally more budget-friendly, but JIC fittings offer long-term value due to their high-pressure resistance and reusability.
