Gripper Test Plugs are blocking plugs with a wide, wing-nut closure mechanism for easy installation without tools. They are made of ABS glass reinforced materials with a rubber O-ring, zinc-plated carriage bolt and extra large zinc wing nut. Tightening the wing-nut by hand expands and seals the plug against the pipe's internal walls. These plug are rated for 17 PSI or 40' of head pressure.
