Bending Stainless Tubing on a Pneumatic Oil & Gas Valve

We use locking wrench style vice grips to hold our tubing while cutting. You also need to make sure your stinger is level when getting your measurement. Your tubing is crooked because you didn't level your stinger.

All bends to your left, center to center, also the hand tight and 1/4 turn is only with swagelok fittings, parker fittings as the ones shown need a little more, make sure you use a square on your tube after bending, it has a spring back, so going a 1/16th over your degree will give you the true 90, best practice too is to mark your tube around at the top of the fitting with your tube in to make sure you’re not short ferruling it

I would use thread sealant not thread locker. Most of your method is ok, I would never clamp or use pliers to hold the tube. It is one and a quarter turns for 1/4 to 1" for proper engagement of the tube fitting (I would have to look up over 1") and only 3/4 turns for 1/16, 1/8, and 316" tube. I have always tightened the nineties to the desired location and then tubed, you guys must find leaks there often.

Oh, and use a back up wrench!

There is a mark on the bender in front of the "latch" that indicates the required minimum straight tube required for proper fitting engagement.

Get a proper deburring tool

Hi, great and informative video on tube bending. Could you tell me what is offset calculation multiplier for 15°, 60° and 75° angle?

Good and wonderful work, thank you professor

THANK U SIR ❤

Tube ka size kya hota hai

Good job

As a beginner instrument technician, that was helpful.
Thanks in advance.

Great!

THREADLOCKER IS NOT THREAD SEALANT.

Im so confused with the line he made in that tube I thought you have to line that with the L line. Looks like he was short but after bending it, it looks like he really hits 90 degrees. Im so confused hahaha

Tengo una duda la letra R' que me indica ??
