Steel Plugs

Inverted flare steel plugs are used on hydraulic brake, transmission and fuel lines as well as LP gas lines to plug lines that are not in use. The internal inverted flare creates a strong metal to metal seal. They are made of zinc plated steel for strength and fair corrosion resistance and can withstand up to 2,800 PSI. Used on copper, brass and steel tubing.
