Product Details

Tapered Caps

The Tapered Series can be used as either a cap or plug* depending on application. Their narrowed design makes it easier to install them in smaller openings and keeps them snuggly rooted in place for as long as necessary. Excellent for protecting threads and keeping unwanted contamination out of pipes, valves, tubing and most other cylindrical openings. These tapered caps are the most economical solution for protecting standard size threads, unified threads, N.P.T. and metric size fittings or ports. So, if you need a versatile solution for protecting certain components, tapered caps are a great option to consider.
*Refer to plug sizes HERE.
