The Bulkhead Union Fitting provides a reliable way to connect a pressure gauge to a pressurized system through a barrier. It allows pressure from the system to reach the pressure gauge for accurate reading. It helps operators monitor system pressure during operation. It supports stable pressure flow while maintaining separation between system sides.Attributes:• Enables the connection between the pressure gauge and the engine pressure source.• Allows measurement of intake manifold pressure during engine operation.• Provides a stable pressure signal for gauge readings.• Suitable for 1/8 inch inner diameter tube fitting.Applications: The Bulkhead Union Fitting is found in panels or enclosures where pressure gauges interface with pressurized systems. It allows system pressure to pass through the barrier to the pressure gauge.
