2 inch Mechanical Gripper Plug

2 inch Cherne Original Gripper Plug – Mechanical Test Plug for Sealing and System Isolation

The 2 inch Cherne Original Gripper Plug is a mechanical pipe plug engineered for sealing and pressure testing piping systems. Designed for use in a range of piping materials, including cast iron, steel, copper, and plastic, it delivers dependable sealing in both low- and high-pressure applications. This plug is commonly used in DWV systems, water lines, and piping isolation procedures.

The plug features a non-slip rubber gasket and a corrosion-resistant zinc-plated steel body, which together provide a positive seal and long-term durability under field conditions. Its expanding rubber ring is actuated by tightening the wing nut, allowing the plug to grip the internal wall of the pipe securely without tools.
