- Using a marker, draw a line lengthwise on the nut and extend it onto the adapter.
- Using a wrench, rotate the nut to tighten. Turn the nut the amount shown on the chart.

Similarly, you may ask, how do you tighten hydraulic fittings?
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.
Beside above, how do you tighten NPT fittings? NPT fittings taper for a tighter fit.
- Insert the male thread into the female fitting.
- Turn the male pipe thread in a clockwise direction.
- Continue to turn the male pipe fitting in a clockwise direction until you can no longer do so, approximately two to four full revolutions depending on the size and type of fitting.
Considering this, can you over tighten an fittings?
Over-tightening can damage the fitting or the seal. That said, you should take care to tighten only to the recommended torque. Over-tightening can lead to damaged fittings and/or O-rings, cracked ports and most certainly a compromised connection seal.
What does JIC fitting stand for?
JIC fittings, defined by the SAE J514 and MIL-DTL-18866 standards, are a type of flare fitting machined with a 37-degree flare seating surface. JIC (Joint Industry Council) fittings are widely used in fuel delivery and fluid power applications, especially where high pressure (up to 10,000 psi) is involved.
