i was looking in home depot today and i saw some sink lines braided im installing a t25 dsm turbo i have everything but the return line would those home depot sink lines be ok for that and if so what size my lines has a hole and i dont want to wait a month before diving thank you and god bless you...

 

doubt they would work. sink lines i believe only have 2 sizes which i dont think are large enough to use as a oil drain. you will need at least a -8 to -10an line to properly drain.

 

Find a local shop that makes hydraulic lines and have them make you some braided lines with JIC fittings. Cheaper than AN but just as good for most automotive applications.They will screw into anything that accepts an AN fitting as well.

 

My own concern about sink lines would be temperature. At best, they may have been intended for 180 degree hot water, not the heat thrown off by a turbo.If you've got to use Home Depot stuff to make a turbo oil return line, my advice would be to braze together some sections of thick copper water pipe.

 

how would you know how big -8 to -10 is? sorry for the questions not knowledgeable about lines other wise i wouldnt be asking a question

 

Take the AN number and divide by 20, and you have the nominal inner diameter in inches. For example, -10 AN is 1/2 inch.

 

Home plumbing components are made for water, temps below 140 F., and max 60 psi. They will deteriate quickly in hot oil and create a very expensive mess, do it right the first time. If it was an option, us cheap old farts would be doing it.

 

What I did was use Home depot fittings, and got a section of -10an SS braided line. Worm clamped the SS line to the nipple coming off the turbo, and JB welded another 1/2" fitting with a nipple into the oil pan. 15k miles so far, no problems with it. Spent maybe $20 tops?

 

I used line like this... 4an on my supply and 10an on the return. Have racked about 300 miles so far and it drains great. Its ment for high pressure and hi-temps and is affordable.

Im just throwing the idea out here in case your set up ever has problems!

 

Actually, AN fittings are sized by 16ths of an inch. For example: 8AN is 1/2 inch, 10AN is 5/8ths, 4AN is 1/4.
Good Luck
