Mechanical Plug Warning: We do not specify a pressure rating on the 141-Series Aluminum Expansion Plugs. As the plug is expanded out there is less seal contacting the wall and thus these plugs have lower back pressure capabilities. Use for very low pressure test or temporary closure only.

Note: Expansion plugs are less effective at higher limits of expansion than in the mid range. Let us help you by supplying the proper sizes for your requirements.
