Thanks for the input Inquisition. I was under the impression I had to have 2.5in couplers for my 2.5 IC piping.
I guess I'll make another trip.

 

That doesnt make much sense. See if its ID or OD and go from there.

 

go to a semi or diesel supply store and ask for high pressure silicone hose in your desired diameter. Its good ----, and fairly cheap. I got about 3 ft for around $20 or $25. They should sell t-bolts or badass worm clamps there too. But i've read that NAPA carries the same ----. There was a thread on here somewhere with the part number. Google it neeegrow

 

PVC's dimensions aren't actually what they say they are...1.5" PVC has an OD of 1.9". 2.0" PVC is something like 2.5". Just take a coupler over to a piece of conduit in the electrical isle. It's about .5" difference. I don't know why he would waste his time and money on HD couplers when the suck and aren't worth the $2.5 a piece....

 

the HD 2 in couplers fit on 2.5 in pipe just fine, in fact, they'd be a little loose on 2 in pipe. For 7lbs, you're not going to have a problem. The worm clamps do loosen over time though, and make sure you flare or put a bead at the ends of the pipes to keep them from sliding/popping off. I didn't have any problems at 5psi but when I jumped to 10 i couldn't keep the damn things on. Then I flared the ends, and had less problems. Be advised, the shitty ebay knockoff silicone couplers suck dragon **** and are worse than HD, they are way to stiff.

 

appreciate the input EG

 

Buy this: McMaster Carr PN: 5285K94

Buying anything other than this product is retarded.

 

Just hit up mike at LSD and get coupler from him, and while your at it might as well get t-bolt clamps too.

 

If you used one of the thousands of tape measures availible there, you'd have noticed the 2" is for 2" sch40 pipe, which is ~2.5" OD. :1

That mcmaster stuff is basicly what NAPA is said to sell. I'd guess you'd have to look around, but the Tractor-Trailor/diesel and farm supply places should have radiator hose like that. Most systems are meant to handle 16psi at 220F, so its good stuff.
