A vacuum probe (20,120) with an upwardly and inwardly sloping frustoconical outer sidewall (26,126) incorporates a connector (50,150) which forms the male half of a vacuum line quick connect/disconnect fitting. An axial passageway (48,148) extends through the probe (20,120) and has an automatic shutoff valve positioned therein. Attachment of a vacuum line to the connector (50,150) opens the passageway (48,148). Sealing tape (66,166) is positioned around the outer sidewall (26,126), and the probe (20,120) is positioned between a vacuum pressure bag (8) and a workpiece (4,6). A vacuum is applied between the bag (8) and the workpiece (4,6) to seal the bag (8) around the tape (66,166) and to evacuate air between the bag (8) and the workpiece (4,6). The probe body (120) may be integrally formed. Alternatively, the probe body (22) may be formed separately from a vacuum line fitting (34,36) which defines the axial passageway (48) and is received into an axial opening (28) in the body (22).

A vacuum probe comprising a bottom portion having a bottom surface with a recess formed therein for developing a vacuum between the probe and a workpiece, a top portion, outer sidewall means sloping upwardly and laterally inwardly from said bottom portion to said top portion, a vacuum line connector projecting upwardly from said top portion for attaching the probe to a vacuum line, and an axial passageway extending through the connector and communicating with the recess; said sidewall means forming an outer annular sealing surface for receiving sealing material to sealingly engage a vacuum pressure bag when the probe is positioned between the bag and workpiece with the connector projecting through an opening in the bag and a vacuum is applied through the axial passageway.
