What the heck is this?
hey guys i was looking at my radiator hoses that go into the heater core and my arm tapped this line and it snapped. this was ver brittle, but can't figure out what it is, i thought it was a hard worn out vacuum line but on the end of the lines they have like a barb that goes into these fittings, i've never seen a vacuum line with these. heres some pics and sorry for the quality

i understand that the fittings would have barbs, but the line that snapped off had a barb that went into the fitting. so if it is can i buy a vacuum line with a barb on it at kragen or something?

i don't know that the local auto parts store will have the barb.
the easiest fix is to slide a piece of regular vacuum hose over the two broken ends as a repair sleeve. it needs to be a nice snug fit.
if you do something different, know that the dime sized cylinder in the first picture is a check valve.

Vacuum lines are made of a very rare material, known as Unobtainium. They have to be due to the harsh demands that vacuum puts on them. The corrosive nature of vacuum, and its propensity for escaping at any available opportunity, coupled with its amazing ability to flow thru the smallest of cracks, makes the high dollar material a requirement for this application.
Ok. All BS aside..... The plastic vacuum lines have a limited lifespan, simply due to the environment they hang out in. It gets HOT in the engine compartment, and over time, the plastic lines dry out, and get brittle. The 'soft' lines do the same thing, they basically harden, and become brittle. When replacing lines, I almost always use the soft line, as it lasts longer, and is less of an ordeal to deal with when it comes time to replace it, or move it around..... doesn't blow itself into a million pieces quite so readily.

It gets hot in the engine bay? No shiat?
Seriously, I've had to replace a couple of hard vacuum lines on my truck and used some that were pulled from a wreck. They don't always go bad, so I guess the best advice is to do whatever is needed to get things to work.
