How to Order the Correct Jetter Nozzle Inserts

An insert order needs more than a thread size. The part must match the nozzle, its assigned jet position and the verified operating configuration.

Identify the exact nozzle first

Record the family, part number and inlet size. Confirm whether it is actually insert-ready. Small factory-drilled Rambo and Rotor models do not accept replaceable rear jet inserts.

Separate thread size from orifice size

M5, M6, M8 and M14 describe insert threads in applicable KEG configurations. They are not the nozzle’s hose connection or the water-orifice diameter. Material, head form and other model-specific details also matter. Use the insert fit guide to organize the request.

Preserve each jet’s assignment

Forward, cutting, rotation and propulsion positions can have different requirements. Do not swap positions or choose a larger forward insert just because a total-flow calculation appears to balance. Use the verified configuration and manufacturer’s service information.

Provide the operating setup for sizing

For a detailed insert-sizing review, supply operating GPM, working PSI, hose inside diameter and working length, plus the nozzle identification. The required total is checked across all jets at the calculated nozzle pressure. A pump-pressure-only example is not a ready-to-build configuration.

Keep the confirmed configuration with the truck

Record the exact part numbers, orifices, quantities and positions. If an existing record conflicts with the tool, stop and resolve it before replacement. Use the manufacturer’s installation and inspection procedure with the equipment isolated and depressurized.

Compare materials using service history

Steel and titanium ceramic options depend on the exact model. Compare actual replacement intervals and costs. KEG lists one-year steel and five-year titanium ceramic insert coverage under its terms; see the warranty matrix for component distinctions.
