i have a k&n ait filter on a pipe iwant to attach the pipe to the turbo but need to know what to use? will a rubber coupling from Home depot work?will the heat melt it? what should i do? thanks Brian

 

A rubber coupling will be fine as long as it is not to long as it will squeeze in and contract, causing reduced flow!

 

Yeah, as civicvtec said a rubber coupling will work. I've heard that the home Depot plumbing couplers don't last though. I can't recall exactly why people don't like to use them but I thought it had something to do with them cracking and basically dry rotting apart. That of course in time could cause boost leaks.
Theres been a few posts on these things already, look around and see if you can find them. I'm sure the Home Depot ones will work fine for a little while, but see if you can pick up some silicon couplers sometime.

 

use tha home depot coupling damn it, even if it wears out after a while its only 3 buxx, if you buy 5 of them its still better than buying one hks boost coupling for 25 buxx.

 

Oh yeah, I forgot this was HMT... Stock up on them I guess. lol

 

lol

 

I was at home depot earler today getting my grill paint (good to 1200!) and looking at te couplings I'll need to buy ina few weeks... bastards didnt have any 2.5"! Just 2" and 3"! psh!

 

belive it or not,
i bought the 3in and it fit my 2.5 perfectly

 

Thats couse its 2.5" interior diameter.Out side is probabaly like 2.75".
The 3" should be ok.You can also buy 300 degree radiator hose at Napa auto parts for like 2 bucks a foot.I bought some the other day.

 

I figured you would know the answer to that one. I just stole/found a ---- load of those couplers from some plumbers. I even got some flexable ones. I saw some that had a metal shield around them. They look crazy. I wonder if they hold a higher rating than the regular rubber ones?
