ABSTRACT:
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).
