I have 5 female camlocks for sale. 4 are type C (with 1/2" hose barb), and 1 type D (1/2" female NTP). I'll sell for $10 each.
Full disclosure...I've upgraded my female camlocks to the "Big C" type sold by brewhardware.com out of New Jersey. They're full port (1/2" ID) female camllocks. They sell for $9 each + shipping. That said, these are in good shape. PM me if you need them.
