Find the right replacement insert
Start with the nozzle model or part number and the jet position you are replacing. M5, M6, M8 and M14 refer to insert threads, not the nozzle’s hose connection.
Identify the nozzle and the front, rear, cutting or rotation jet that needs service.
Match the specified thread, seat and material to that exact position. A matching thread alone does not establish compatibility.
Use the approved orifice configuration for your setup. Send your GPM, working PSI and any existing insert markings when requesting parts help; do not choose an orifice diameter by appearance.
Steel inserts have one-year coverage. Applicable KEG titanium ceramic inserts have five-year coverage. See the warranty terms for the exact component.
Replacement parts and insert holders do not turn a factory-drilled nozzle into an insert-ready nozzle.

Shipping: In-stock replacement inserts normally process in 1–2 business days, followed by 2–3 business days of standard transit. Standard ground shipping is free at $199+ within the continental U.S.
M8 replacement jet inserts for compatible KEG nozzles. Replace worn inserts to service the nozzle’s working jets. Choose the steel or titanium ceramic material option shown on this listing.
Confirm the replacement part
M8 is the jet-insert thread, not the hose connection. Match the nozzle model, jet position, insert part number, head style and orifice. A matching thread alone does not confirm compatibility. Contact JPS if you need help identifying the exact replacement.
Manufacturer warranty
Steel inserts carry a one-year manufacturer warranty; titanium ceramic inserts carry a five-year manufacturer warranty. Coverage is subject to the manufacturer’s terms. Separately purchased insert returns follow the JPS return policy.
KEG makes sewer-cleaning nozzles and cutters for a range of applications and connection sizes. Its equipment is also listed in MSW’s municipal sewer-nozzle directory. Choose the specific model for your work; designs and service requirements vary.
The practical value is a tool chosen for the task, a matching setup and support after the sale. Job time and water use depend on the machine, line and obstruction.
Match the insert part, thread, head style and orifice to the nozzle and jet position. Thread size alone does not establish compatibility. Confirm the service part with JPS before ordering.
JPS confirms insert sizes for the supplied nozzle using operating GPM, pump PSI, hose inside diameter and hose length. Do not choose replacement inserts from hose-connection size alone.
Dispatch timing depends on this item and its configuration. Contact JPS to confirm timing for a scheduled job.

Buying for a fleet or a city crew?
Net 30 applies only to eligible 3/4-inch-and-larger equipment on approved B2B accounts. Items 1/2 inch and under are credit-card purchases. Request an equipment quote or call (864) 804-6637.
What matters after the purchase
Judge the tool by the work it covers, the parts you can service and the support behind the setup.
Service the right components
KEG: On insert-equipped KEG models, replace the specified inserts while the body remains serviceable. Drilled-jet models have different service needs. Match the part, position and orifice to your nozzle.
JPS’s 30-day performance guarantee accepts normal testing wear on a complete eligible nozzle or kit, including supplied inserts. Return all supplied components. Eligibility, exclusions and prepaid-label instructions are in the return policy.
Look for the exact nozzle and configuration, machine flow and pressure, hose, pipe condition and the work completed. Compare before-and-after inspection of the same section. One successful job does not establish a universal speed, water-use or service-life advantage.
Compare cost over your own jobs
Compare purchase price, replacement parts and service costs over the same number of jobs. Record time and water used on comparable work. A useful cost per job is total tool and service cost divided by jobs completed; any time savings should come from your own measured results.
