Note: We do not specify a pressure rating on the 144-Series Nylon Expansion Plugs. As the plug is expanded out there is less seal contacting the wall and thus 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. Price subject to change without notice Petersen Terms & Conditions Apply |
