I was removing what looked like radiator hoses from a plastic peace (I say looked like because the hoses ran into the dash) that I've pictured below. While doing this, the hoses did not exactly separate from the plastic peace very well and the hoses decided that they just could not part with the nipple. so now I have this plastic peace that I'm pretty sure I probably need it in one peace.
I'm asking here before I go to any parts store because I don't have a lot of confidence in their ability to identify it. If you need more/better pictures, please let me know and I'll attempt to comply.
In the future, when removing hoses, if the old ones are really stuck on, it's better to cut them off. Use a utility knife, and cut through enough of the hose that you can peal it off, without undo stress on the other parts of the cooling system (this valve, radiator, heater core, etc.). But do not press so hard that when you cut through, that you cut into the part underneath. This will help avoid damage to those parts. Particularly the heater core, which is a PITA to get to if you crack a soldered joint inside.
thanks for that bit of information. I'll remember for next time, hopefully I don't run into too many problems with that but I'm not getting my hopes up here. thanks guys

I see that you've altered his syntax a bit. I'm assuming the bypass is to prevent any coolant making it's way to the heater core so that it can heat up more quickly? similar to the way the thermostat works?
When you slide the temperature all the way cold, it opens a small valve on the hvac controls. This applies vacuum to the divert valve, bypassing the heater core. Anything but full cold, there is no vacuum applied.
Presumably, this to assist the cooling efficiency (effect?) of the a/c.
now to see if any local part stores would have that.
