The NPT series from Caplugs (Buffalo, NY) is designed to seal out dust, moisture and other contaminates, protecting NPT fittings against thread damage during shipping and storage. Made from white high-density polyethylene, the NPT Series features a tapered design for a tight fit that does not seal all the way down on the fitting. Available for 2”, 3” and 4” threaded fittings, each plug includes a 1” lug on top of the part for easy installation and removal. More cost effective than traditional PVC-style plugs, Caplugs’ threaded plugs are lightweight, durable and securely protect NPT fittings from damage.
