A cylindrical circuit board socket with a metal body open at each end having a pair of lead contact fingers extending from one end into the interior of the socket for forming an electrical connection with a lead inserted into the socket and a pair of circuit board contact fingers extending from the other end along the outside of the body for holding the socket in a circuit board hole prior to soldering the socket to printed circuitry at the hole. A seal at each end of the body closes the interior of the body and prevents flux and solder from flowing into the interior of the socket during fluxing and soldering of the socket. A contact lead is easily inserted into the socket through a seal to form an electrical connection with the interior fingers.
