In many fluid and gas systems, accurate pressure measurement is critical for safety, performance, and compliance. During maintenance, calibration, or quality assurance processes, it is essential to verify the integrity of low pressure gauge and associated connections.

Previously, test setups often relied on makeshift fittings or adapters, which posed risks such as inconsistent sealing, time-consuming setups, or potential for leaks that compromise test validity. This PR addresses those issues by implementing a dedicated test plug that is purpose-built for pressure gauge testing environments.

Key Features

• Secure Connection: The plug ensures a tight seal with standard pressure ports, preventing leaks during pressure buildup and hold phases.

• Repeatable Fit: Designed for quick installation and removal, improving testing efficiency and reducing wear on mating threads.

• Durable Construction: Fabricated from corrosion-resistant materials suitable for a range of gases and liquids under varying pressures.

• Versatile Compatibility: Compatible with a range of pressure gauge threads and fittings used in industrial applications.

Implementation Details

• Added new test plug design to the component library.

• Integrated threading profile to match standard gauge ports.

• Verified compatibility with internal leak detection protocols.

• Performed bench testing with standard pressure ranges to validate seal integrity and performance under cyclic load.

Testing

• Leak Testing: The plug was tested under both low and high-pressure conditions using nitrogen and air. No observable leakage was detected up to the maximum rated pressure.

• Mechanical Fit: Confirmed repeatable engagement with pressure ports across multiple cycles without thread damage or seal degradation.

• Environmental Exposure: Exposed to humidity and temperature cycling to confirm material stability.

Impact

This implementation improves the reliability and efficiency of test plug for pressure gauge workflows. It reduces dependency on ad-hoc components, minimizes the risk of test failures due to leaks, and supports maintenance teams in achieving consistent results.

Next Steps

• Evaluate usage feedback during field testing.

• Explore options for expanding compatibility with additional port sizes and connection types.

• Develop maintenance guidelines and a tracking system for wear and reusability.
