M20 NOx Sensor Thread Chaser - Lisle

Ensure the integrity and performance of NOx sensors in late-model diesel exhaust systems with the Lisle 12220 M20 NOx Sensor Thread Chaser. This specialized tool is engineered to meticulously clean and restore M20 x 1.5 sensor threads, preventing costly damage to new sensors and exhaust bungs. It's an essential service tool for professional technicians to facilitate proper torque specifications and a reliable, leak-free seal for emissions-critical components.

Key Features

• Dedicated M20 x 1.5 Size: Specifically designed for servicing M20 NOx sensor bungs found on light-, medium-, and heavy-duty diesel exhaust and emissions systems.
• Precision Thread Restoration: Functions as a robust nox thread chaser to effectively remove carbon buildup, rust, and debris without excessively cutting or weakening existing threads.
• Protects Critical Components: Helps prevent cross-threading and stripping that can damage expensive NOx sensors or exhaust bungs, promoting reliable sealing and sensor performance.
• Professional-Grade Construction: Manufactured by Lisle for durability and repeated use in demanding shop environments, suitable for diesel repair facilities and fleet maintenance.
• Compact Access: A short overall length, usable with a 13/16" hex socket or a 3/8" square drive, provides improved access to tight areas around turbochargers, DPFs, SCR units, and other aftertreatment components.

Applications

The Lisle 12220 M20 NOx Sensor Thread Chaser is an indispensable tool when servicing diesel emission systems on pickups, commercial trucks, buses, and off-road equipment equipped with M20 NOx sensor mounts. Use this nox sensor tap to clean slightly damaged or contaminated threads in exhaust bungs before installing new NOx sensors after failure, fault codes, or emission-related repairs. This dedicated nox sensor thread chaser m20 tool helps maintain correct emissions performance, proper torque, and long-term sensor reliability.
