PerformancePLUS Alliance Plunger Assy

Replacement PerformancePLUS plunger assembly.  Used in Alliance 2695.  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, while 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 while safeguarding pump flow rates and system retention times.
