Pipe Thread Ring Gages - "NPSM" Straight Pipe (ASME B1.20.1)

NPSM (National Pipe Straight Mechanical) straight pipe thread ring gages are used to inspect the quality of external threads on pipe fittings and other components that utilize NPSM threads. These threads are designed for mechanical joints where there is no internal pressure, such as hose couplings and certain types of pipe fittings.

Key Uses of NPSM Straight Pipe Thread Ring Gages:

• Quality Control: Ensuring that manufactured parts meet the specified tolerances and standards for NPSM threads.
• Inspection: Verifying the accuracy of thread dimensions, including pitch diameter, major diameter, and thread form.
• Maintenance: Checking the condition of existing threaded components to identify wear or damage.
• Troubleshooting: Identifying the root cause of assembly issues or leaks related to thread incompatibility.

By using NPSM straight pipe thread ring gages, manufacturers and maintenance professionals can maintain high quality standards, prevent costly failures, and ensure the reliability of products and systems that rely on NPSM threaded connections
