Grease Fitting Plugs

Grease plugs, sometimes considered pipe plugs, are an externally threaded plug crafted from carbon steel. They feature a variety of head types including square, hex, and hex/slotted for easy installation and removal. They are ideal for sealing lubricant outlets of injectors, manifolds, or other locations where lubrication points are no longer needed.
