Key Features and Performance

• Bulkhead Design: Specifically designed for panel mounting to facilitate easy piping transitions through enclosures.
• Keyed Feature: The blue keyed sleeve ensures that this component only couples with matching keyed stems, preventing accidental intermixing of different fluid or gas lines.
• High Pressure Capability: Rated for up to 3000 PSIG at room temperature when coupled, ensuring reliability in demanding instrumentation environments.

Pressure and Temperature Ratings

The pressure rating for coupling and uncoupling operations is 250 PSIG @ 70 °F (17.2 BAR @ 21 °C). At the maximum temperature of 400 °F (204 °C), the coupled pressure rating is 250 PSIG (17.2 BAR).
