Thick Extra Wide Flange Tapered Plug Caps are inexpensive fasteners with a dual function closure that can be used as either a plug or a cap. Flange tapered plug caps are easy to handle, and this thicker and wider flange prevents the plug from pushing through the opening.

Thick Extra Wide Flange Tapered Plug Caps meet aircraft, aerospace and defense industry standards. These Plug Caps are stocked in sizes to plug holes from 0.125" through 6.620" and to cap parts from 0.060" through 6.630" diameters. Recommended uses include tube and hydraulic fittings, tube end caps, pipe caps or product protection.
