Tapered plugs are an excellent option when you need a low-cost, effective product to protect tubing ends, threads and ports during shipping and storage. The tapered design goes on easily and stays put. The tapered design naturally allows each particular size to fit into or onto a number of different diameter tubes. And, with sizes that range from a fraction of an inch to over 4.5 inches, there is a T-Plug for virtually every application.

The Flexible Alternative
While polyethylene tapered plugs are flexible in relation to their tapered design, they are not pliable like vinyl materials. For greater flexibility, consider our line of vinyl Plus Plugs as alternatives.
- Made from a flexible vinyl material, these plugs typically provide a more secure fit than the rigid polyethylene tapered plugs.
- Vinyl material adapts as it is placed into a hole - as pressure from the insertion process is released, the flexible vinyl material expands inside securing a tight fit.
- Vinyl Plus Plugs are also typically easier to install and do not crack, split, or shred in the way that many polyethylene caps and plugs will over time.
