Oatey Gripper Mechanical Plugs are ideal for plumbing system tests. They're easy to install with an extra-large wing nut. The inside of the pipe seals inside pipe as far as needed. Plugs are made with glass-reinforced ABS plastic. End-of-pipe seals only at the end of a pipe, preventing plug from falling into stack.
Plug is rated for 17 psi or 40 ft of head pressure
Extra large zinc wing nut for ease of tightening, no wrench required
Natural rubber o-ring for excellent expansion and memory
ABS glass reinforced plates for added strength
Zinc-plated carriage bolt resists rust and corrosion
