Direct Drive End Cap

A water-end manifold component used in direct-drive pump assemblies to close and support the high-pressure water section. It provides the machined sealing interface for adjacent water-end components and helps maintain proper alignment under repeated high-pressure cycling. This part is typically replaced when the existing end cap shows wear, sealing-surface damage, corrosion, or fatigue around the manifold connection points.
