Injector Seat Cleaning Kit 429pc Diesel Port & Shaft Cleaner

An injector seat cleaning kit for cleaning diesel injector seats, bores, cups and inner seat holes before refitting or servicing. The 429-piece layout gives you a wide selection of brushes, swabs and drive components to deal with carbon, rust and debris across a range of diesel applications.

Used for vehicle maintenance, injector servicing and general garage or workshop repair work, this kit helps when preparing seating areas properly before injectors go back in. It suits mechanics, diesel specialists and experienced DIY users carrying out cleaning work on injector ports, cups and shafts, especially where built-up contamination can affect fitment or sealing. The mix of brush styles also makes it useful when moving between deep seats, inner seat holes and bore cleaning without relying on one brush for every stage.

The supplied brush selection includes helix brushes for deep seat cleaning, two-stage brushes for seat and inner seat hole cleaning, and bore brushes for tube wall and bore work. Stainless steel brush construction gives a hard-wearing cleaning surface for repeated workshop use, while the 1/4in drive hex shaft allows quick interchange between brushes, extensions and even low-speed drill use where appropriate. A driver handle and rigid extension use a spring-loaded quick-lock coupler, and the flexible extension has a flush locking screw to help reach awkward areas. Low-lint swabs from 5mm to 16mm are included for cleaning and polishing injector bores and cups, which helps keep the job organised when different diameters are needed.
