M38 x 1.5 Metric Threaded Sealing Plug | Yellow HDPE

Commonly used across engineering and manufacturing, this M38 x 1.5 metric threaded plug provides a visible seal for prepared threaded openings. The wording and fit make it suitable where teams need a yellow metric sealing plug rather than a permanent metal plug.

The threaded form allows the plug to locate securely in matching metric threads, helping reduce accidental loss during movement around busy workshops. This version combines a 20.6mm length with a 48.0mm head size, giving a clear size reference for matching against the threaded port.

Common Applications

  • Thread protection during powder coating or painting
  • Temporary sealing on valves and pump housings
  • Maintenance repairs on fluid handling equipment
  • Protecting fittings in stockroom storage
