UTMALL Diesel Injector Seat Cleaning Kit 19‑Piece — Brass, Nylon & Wire Brushes with Long Driver and Sealing Plugs

UTMALL’s 19‑piece injector seat cleaning kit is a complete, portable set of brass, nylon, silicone and wire brushes plus drivers and plugs designed to clean diesel injector seats and shafts without damaging the seat surface.

This organized kit brings together size‑matched brushes, a long bit driver with quick chuck, sealing plugs and adapters in a molded plastic case so you can access, clean and protect injector cups and shafts on a wide range of diesel engines. Each brush type and size is chosen to tackle carbon, rust and residue while minimizing scarring to metal surfaces, and the included accessories speed reassembly and testing.

How does this kit remove carbon and rust from injector seats?

The combination of brass, silicone‑nylon and steel brushes lets you attack different deposits progressively. Start with softer brushes for delicate finishes and use wire or brass brushes for heavier corrosion; the driver keeps rotation steady for consistent cleaning.

• Brass brushes (18mm, 20mm, 24mm) for medium deposits.
• Plastic brushes (15mm, 17mm, 18.5mm) for non‑marring scrubbing.
• Silicone‑nylon (15mm, 10mm) for gentle cleaning and sealing surfaces.
• 8mm wire brush for heavy rust and carbon buildup.

Which engine types and injector sizes will this set fit?

The kit is made for most diesel applications where injector seats and shafts need cleaning, covering a range of common seat diameters. The multiple brush sizes and the 5.9‑inch adapter let you reach recessed seats on trucks, agricultural engines and industrial machinery.

• Three brass sizes to match common steel injector cups.
• Plastic and silicone brushes for sensitive or alloy seats.
• Long bit driver and adapter for deep or narrow ports.
• Port sealing plugs to protect surrounding openings during work.

What accessories are included and how do they speed up the job?

The kit supplies drivers, adapters, insertion rod and sealing plugs so you can clean and then reseal ports quickly without improvising tools. The molded box keeps components organized and portable, reducing downtime between operations.

• 8.5" long bit driver with quick chuck for steady rotation.
• 5.9" adapter and insertion rod for deep access and alignment.
• Six port sealing plugs to protect openings during cleaning.
