Threaded Caps

Metric, American standard, NPT, BSP and more threaded caps
Threaded caps offer a more secure fit to protect threaded connections or leads on a variety of products. Caplugs stocks a variety of plastic and metal threaded caps to protect your products from dirt, moisture and other contaminants and ensure threads aren’t physically damaged.

Beyond offering a tighter and more complete seal, threaded caps serve as barrier to dirt and damage, and can also be used as masking caps for finishing operations. This can include protecting threaded ends during dipping, painting, e-coating or plating work. Caplugs also offers an extensive range of threading options for these caps, allowing you to select the right cap, regardless of whether you need to protect JIC threads, metric threaded products, NPT threads, American standard threading or some other option.
