Sealing Plugs

Niagara Caps & Plugs introduces three styles of sealing plugs to protect unified, metric, and BSP fittings and ports. Each plug features a unique and integral Tight Fit™ sealing lip along with five complete threads. This design prevents contaminants from entering or fluid from escaping fittings or ports without the need for an o-ring. They can be inserted or removed by hand, screwdriver, socket wrench, or power tool.
