87K Nozzle Body 4"

Designed to support and align the nozzle stack in Flow waterjet systems operating up to 87,000 psi. It provides the rigid body structure needed to hold the orifice, mixing chamber, mixing tube, and retaining components in proper concentric alignment, helping maintain stable jet formation, consistent abrasive draw, and repeatable cut quality. This part is commonly replaced when the nozzle body shows wear, thread damage, erosion, or alignment issues that can shorten consumable life.
