NOTE: Parts listed on this page are components of first generation 4215 & 3615 fluid end models no longer sold. These
models utilize different stuffing boxes, valves and manifold than the current “HF” design. “HF” and first generation models can be most
easily distinguished by the part number stamped on the top face of the fluid end manifold. Current (HF) models use manifold part
number 52864 while first generation fluid ends featured on this page use manifold part number 50896.
