A gas connector (10) including a nipple element (12) has two boreholes (20, 22) formed in the nipple (12) extending lengthwise therethrough. The boreholes (20, 22) diverge as they extend from the sealing end (15) of the nipple (12) to the connecting end (18). Butt weld protrusions may be formed in the connecting end in commuication with each of the boreholes. The protrusions (26a, 26b) are provided for welding gas tubing (32) to the nipple (12) at the terminal ends of the respective boreholes (20, 22). One of the boreholes is used for transmitting a process gas. The other borehole is used for introducing a purge gas into the gas supply system (100) in which the connector (10) is used. The nipple element (12) may also have its connecting end (18) adapted for connection to other gas conveying assemblies, such as cross-purge assemblies. |
