Bullet End Plug Insert Cap (also commonly known as a bullet cap or inside eye fitting) is a specialized hardware component designed to cap off the open, raw edges of metal tubes and pipes. In marine environments, these plugs are heavily integrated into Bimini canvas frames, boat railings, stanchions, and swim ladders. They create a rounded, snag-free endpoint that protects passenger clothing or lines from catching on sharp metal edges.
For marine applications, these are investment-cast from 316 marine-grade stainless steel and polished to a high-mirror finish. This alloy blend protects the internal and external surfaces of the tubing against rust and pitting from constant saltwater spray.
Pro-Tips for Installation
1,Sizing Check: Make sure to double-check the wall thickness (gauge) of your metal pipe before purchasing. Since these caps plug the inside of the tube, a pipe with exceptionally thick walls might require you to lightly sand down the insert portion of the plug for a proper fit.
2,Securing the Cap: While some bullet plugs fit snugly via friction alone, most marine setups utilize a light tap from a rubber mallet to seat them. For permanent, rattle-free installation on a vibrating boat, add a thin layer of marine-grade epoxy or retaining compound inside the tube before tapping the cap home.
