How Do You Tighten A JIC Fitting?

Should I use Teflon tape on hydraulic fittings?

You don’t need or should use any teflon tape or pipe dope on hydraulic fittings.

Neither are designed for those kinds of pressures and using them could create a less then perfect mating between connection surfaces causing more harm than good..

How do I know my JIC fitting size?

NPTF, BSPT and BSPP measure 1/4” larger than their actual size. For example, a 1/4” NPTF, BSPT or BSPP will actually measure 1/2” on the O. D. of the threads. JIC, SAE O-ring & Flat Face threads measure as listed below. The first number listed is the size of thread, the second number is the threads per inch.

Does JIC fit NPT?

JIC fittings is absolute different seal, not interchangeable. JIC hydraulic fittings is used in high pressure system, NPT fittings is used in low-pressure system. NPT pipe threads have always been popular, as leaks can be fixed by simply tightening the fitting.

What is better flare or compression fittings?

Fittings: Generally speaking, compression outlets are used for water and compressed air lines, where slight leakage isn’t going to cause too much of a problem. Flared outlets are used for gas and high-pressure lines, where even a little leakage can cause major problems if left unattended.

How do you stop a flare fitting from leaking?

Loosen and tighten the flare nut several times to the torque specifications. This action will positively seat the cone into the flare. If the joint still leaks, dissemble the connection and wipe off the flare and the cone with a rag.

How do you tighten a fitting?

Thread the hose end or adapter nut onto the fitting until it cannot be tightened by hand any further. Lightly tighten the nut with a wrench (approximately 30 in. lbs.) making sure it does not bind; this is also known as tightening until wrench resistance.

How does a JIC fitting seal?

JIC fitting systems have three components that make a tubing assembly: fitting, flare nut, and sleeve. As with other flared connection systems, the seal is achieved through metal-to-metal contact between the finished surface of the fitting nose and the inside diameter of the flared tubing.

How does a JIC fitting work?

JIC fittings rely on metal-to-metal contact between the finished surface of the fitting nose and the inside diameter of the flared tubing to make a seal. SSP takes great care in the manufacturing process to produce a flared nose surface that far exceeds published specifications.

Is JIC and NPT the same?

JIC 37⁰ Flares: The Joint Industrial Conference (JIC) fitting is the most common hydraulic connection style. … NPT Pipe Threads: NPT pipe threads are your traditional tapered thread fittings and have been used for 100 years.

Why is thread seal not used on flare fittings?

WARNING – Do not use pipe thread sealant or Teflon® tape on any flare ends because you will not obtain a leak-free seal. … -Never loosen a connection after tightening-this may cause a leak. It is always better to tighten more if a leak is detected.

How do you tighten a hydraulic fitting?

JIC fittings should be tightened by hand only until the two connecting surfaces meet. Then, fittings should be tightened with the use of two wrenches to the required number of flats. A “flat” is equal to a one-sixth rotation. To determine the required number of flats, refer to the fitting manufacturer’s manual.

Can you over tighten a flare fitting?

Fourth, don’t over-tighten the flare fitting, as this can cause leaks. Daikin offers preset flare torque wrenches that will allow you to properly tighten the flare fitting without over-tightening them. Always use a backup wrench when tightening any flare fitting.
