NPT Series

Plug for NPT Fitting

Caplugs' NPT Series of threaded plugs can be used as dust plugs to keep out contaminants and moisture, and to protect against thread damage during shipping and storage. The tapered design allows for a tight fit, but the plug does not seat all the way down on the fitting as is commonly found with true NPT tapered NPT threads. Available in four sizes for 2", 2.5", 3" and 4" threaded fittings, all sizes include a 1" lug on top of the part requiring only one tool to tighten and remove.

  • Easy to install and remove
  • Fully threaded to ensure a secure fit
  • Locks tight to keep out moisture and debris
  • Lightweight and durable
  • More cost effective than traditional PVC-style plugs
