not sure what I broke

I took heater core hoses off and broke hose nipple off the plastic piece before it goes into intake .I don't know what that piece is. It has three hose nipples and a vacum line on it.I need to go to junk yard to get piece not sure what to ask for. Anybody know what its called .thanks The car is a 87 camaro with 5.0 tpi.

Too vague. Some pictures would be way helpful or just a better more in depth description...

Could be a heater core valve, not sure. Just take the part to the junkyard, they may be able to figure out what your "part" is. You could also take it to a parts store and ask or try to find the OE number off the part, that might help too.

I found out it is a heater control valve. thanks
