So does anyone know the dif btwn , say, 16 gauge tubing and schedule 40 piping? I am in contact with an industrial mfg'er trying to get a pipe bent to the exact degree and size for a custom air intake for the 2nd gen runner. This may be something that others would want to get in on. Always better to order in bulk, but I would need to get one for test fitting first. Pretty cheap. A 3" 16 ga. Carbon Steel Elbow, 45 x 18" CLR for $13.79. They can bend to any degree and any tangent length. I am in the process of measuring my current setup to find the right degree bend to clear the master cylander so that it all lines up straight.

So I need to know what would be better to have it made from and what size: carbon steel, aluminum or stainless,11, 14 or 16 gauge. Is aluminum able to be welded (for the tube fittings)?

 

aluminum cant be welded properly with integrity without using tungsten inert gas welding (tig)

 

Tubing is measured by O.D., pipe by nominal I.D.

Try a google for tubing and pipe specs and you'll find more than you ever wanted to know...

 

Get the thinnest stuff you can that will take and hold a bend.

Sounds like you will be paying for the welding, so I doubt it matters on the materials. The welder will know how to weld it.

 

Are these mandrel or muffler shop bends? The price is nice!!

 

Try an electrical supply or even a Home Depot type place and get a 3" sched. 40 45 degree or a 90 degree sweep / elbow.

Then just cut the angle that you need.

 

These are mandrel bent. They may also be able to do the welding of the fittings after providing diagrams for placement and a parts list. That, however, will increase price unless you are able to do it yourself. But could be worth it to have it all done for you profesionally.

 

I guess I'm a little confused on the question / Post

Are you trying to get some input on selling them?

I'm not sure what advantage a mandrel bend on a 3" tube at only 20 - 30 deg. would have.

What needs to be welded, all you need to do is drill a hole ad put in a grommet.

 

I was really just inquiring about the difference between tubing gauges and piping schedules. And what type of material would be best to use (aluminum, carbon steel or stainless). I added the other info cuz I knew there were others with 2nd gens who were looking for an air intake (not pvc or $$$) that they didn't have to do much fabing to.

The mandrel is just the bend this mfg'er offers.

Welded hose fittings instead of drilling and securing with a nut on the inside of the tube.

I like paying attention to small details when modding my truck as opposed to just slapping some mis-match parts in there. That's the reason for the welded fittings.

Thanks for input. Maybe I'm just making this harder than it should be.

 

Thats cool,
I dont agree with the nut inside the tube either.

 

Denk: Count me in on one for sure...I have two failed attempts at ISR tubes for my 3.0 already. Just send me pic of what you got when its ready

Aluminum would be cool since its typically light weight and can be polished pretty easily.

I am all for the welded fittings even if it does add to the cost.


Like I said - count me in
