Thank you for this video. I just picked up a return system and I overestimated my skill level, realizing I have never dealt with AN fittings before. So, rather than winging it, I found a good training video.

Use anti seize on those aluminum threads putting those Russell AN fittings together. It really helps when you go to reuse them over time.

Assembling these really doesn't look any different than the reusable hydraulic, fuel, air fittings in use decades ago. At 16:27 when you were putting the end on the hose----i don't know about these----but on the hydraulic, air, and diesel fuel fittings we used (Aeroquip) you would turn counter-clockwise to install the fitting on to the hose and vice-versa, of course, if you were replacing the hose. Not sure why you didn't include a fine tooth hacksaw as a way of cutting hose that is reinforced with steel. Early in my career there was no such thing as cut-off discs. I don't really care for them cutting hose because of the debris they get inside the hose; although you did mention flushing. Good explanation though. Who makes that nice aluminum clamp you were using in the vise? Could of mentioned that in the description.

I have 1982 Mercedes Benz 300D Turbo diesel! I would like to replace oil cooler lines with AN and aircraft style hoses ! It would make the replacement simple compared to the rubber and steel lines which are about 3 feet long with extremely difficult fitting of removal and replacement lines to cooler and oil filter ! I have the new lines but you have to be a contortionist to remove and replace the lines without removing motor mount and jacking up the engine! As it is metric and my first attempt at AN lines I need some help if you could! Thank you !

Thank you! I needed this tutorial. But now.. I meed also those clamps! 😂

Alot of the hard rubber hoses have bends to fit proper how do you route the hoses to match

[jimhiscott]

Completly avoid cutting hose that will be used for fuel injectors with a grinder. Use the big cut off tool you seen him use for all your injector lines. It's just to hard to remove all the dust from inside the line that a cut off grinding wheel produces. I don't need to tell you what happens when those contaminants reach your injectors!

Hi, has top studio size 0.8 also an inner line, or is solid inside?

[shaneorgan]

What’s the little ball in the swivel nut do?

[charles-ihzp]

Only thing I would not do is add oil to the hose itself. The moment you add petroleum base product to the hose it starts to swell making it harder to install. Once you oil the barb on the fitting the hose should be installed in 1 shot.

Can i use the rubber lines with the threaded style fittings? Should of watched this video before trying to repair my own as i crushed my line trying to press the super frayed stainless steel line by hand.

I have an issue. My particular pcv valve outlet is plastic with an ID of 3/4 inch. It's roughly 1.5 inches long with no threads inside or outside.
I want to attach a 3/4 inch (ID) flexible braided hose to this little plastic piece that has no threads whatsoever. What will I need to make the sealed connection?

16:34 hi mate I’m still confuse would you tell me how deep exactly we should put this Nylon hose to hose end?
I believe there is something like ”curb”inside which doesn’t let put this hose deeper?

[chunkybrosroachmobile]

Probably a dumb question, but are u able to reuse the fitting? Say for instance, I wanna shorten the hose can I use the fitting again or will I have to get new ones?

[jasonvogel]

Awesome video! Thanks for all of the great info!

What are the ball bearings on the an fittings? I had one missing and it blew oil everywhere. Is it some type of pressure release?
