Made from the highest quality sapphire, this plunger preserves the life span of the plunger seal. Precise roundness and smoothness tolerances minimize the wear of the plunger seal. Careful concentric alignment of the plunger within its stainless steel holder ensures that the sapphire rides directly into the center of the plunger seal, reducing wear of both parts. Included with the plunger is a pre-mounted C-Clip, which eliminates the need to remount this component.
