Replaceable Jetter Inserts: When to Service the Nozzle You Own

On an insert-equipped nozzle, worn or damaged jet components may be replaceable while the serviceable body stays in use. That is a practical reason to consider serviceability when you buy. It does not mean every KEG nozzle uses inserts or that a nozzle body can never wear out.

Identify the construction before ordering parts

KEG's range includes both factory-drilled and insert-equipped models. The 1/4- and 3/8-inch Rambo models have factory-drilled jets. The catalog's 3/8-inch Cleaning nozzle uses eight rear M6 inserts. The exact model, size and jet position determine which maintenance parts apply.

Use the insert guide and thread identification guide. Do not use the nozzle connection size as a substitute for the insert specification.

Inspect before replacing

Performance changes can have several causes, including the machine, hose, blockage or wear. Follow the manufacturer's shutdown, inspection and servicing instructions. Confirm that the body, seats, threads and other components remain serviceable before replacing inserts. A blocked jet and an eroded orifice need different attention.

Compare the two actual options

• Service: correct parts, any other repairs, labor and downtime.
• Replacement: the correct new nozzle or configuration, setup and any associated downtime.

Use current prices and your own maintenance history. Avoid assuming that drilled nozzles fail every few weeks, that only inserts can wear, or that every serviced nozzle has a fixed number of years remaining.

For a longer comparison, add the actual number of services and replacements over the same period. Divide by comparable completed jobs to estimate cost per job. The insert cost guide explains the calculation.

Plan parts around the truck's workload

Keep a record of each nozzle's part number and configuration so the right replacements can be identified. Check current parts availability and the shipping policy when ordering. Included accessories and service tools vary by product.

KEG's published warranty provides one year on replaceable steel inserts and five years on titanium-ceramic inserts, subject to the applicable terms and exclusions. Warranty duration is not a predicted replacement interval or a promise that normal wear is covered. Read the warranty details.

Buy a complete loadout when you need complementary tools

Servicing an existing nozzle and adding a missing tool solve different problems. If your truck needs opening, cleaning and finishing options, compare plumber kits. If it needs maintenance parts, send JPS the nozzle identification and machine setup for a parts check.
