Caplugs的NPT系列螺紋堵頭可用作防塵塞，以防止污染物和水分，并在運輸和存儲期間防止螺紋損壞。 錐形設計允許緊配合，但是插頭不能完全落座在配件上，如通常在真實NPT錐形NPT螺紋中發現的那樣。 2“，3”和4“螺紋接頭有三種尺寸可供選擇，所有尺寸均包括一個1”凸耳，只需要一個工具即可擰緊和移除所有三種尺寸。

Caplugs' NPT series threaded plugs can be used as dust plugs to keep out contaminents 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 three sizes for 2", 3" and 4" threaded fittings.  All sizes include a 1" lug on top of the part requiring only one tool to tighten and remove all three sizes.

• 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
