Overview

The YCT 7 Pcs Oxygen Sensor Socket Set is a purpose-built toolkit designed to simplify O2 sensor removal and installation across a broad range of vehicles. The assortment covers 22mm (7/8 in), 27mm, and 29mm sizes with a mix of long, short, and deep variants, plus slots or slots-with-harness access. Crafted to endure the demands of automotive work, this set aims to make stubborn sensors more approachable without sacrificing control or protection.

Key Features

• Sizes include 22mm, 27mm, and 29mm with multiple drive configurations (1/2" and 3/8"), plus 6-point and 12-point variants.
• Slotted designs allow removal or installation while the sensor remains connected to the wiring harness, reducing strain on the harness.
• Offset, compact geometry provides leverage in tight engine bays and awkward angles, helping to protect knuckles and gloves.
• Manufactured from premium Chrome Molybdenum steel for durability and precise fit during repeated use.
• Special deep and short versions accommodate deep-set sensors and hard-to-reach spots, with compatibility for common O2 sensor fittings.
• Versatile enough to assist with other under-hood tasks, including oil pressure sending units and vacuum switches, expanding your toolkit.
• Designed for DIY enthusiasts and professional technicians alike, with practical guidance and responsive customer support within 24 hours.

In Practice

Use cases range from routine sensor changes to removing stubborn units on older or tightly wrapped installations. The offset and slotting design helps you work around wiring harnesses without disconnecting them, saving time and reducing the risk of wiring damage. The robust steel construction supports steady torque without warping, while the range of sizes reduces the need to borrow or chase mismatched sockets.

• Quickly swap sensors on a variety of vehicles and sensor types using the correct size and drive.
• Reach sensors tucked behind exhaust components or adapters with the long and deep variants.
• Remove and reinstall oil pressure sending units and vacuum switches with appropriate sockets to minimize strain on fittings.

Specifications and Fit

The kit includes 22mm (7/8 in), 27mm, and 29mm sockets in both long and short forms, with 1/2" and 3/8" drive options. The 7/8"–22mm sensors feature a 7/8" hex nut, while the 27mm and 29mm variants cover broader OEM fittings. Precision casting and Chrome Molybdenum steel construction ensure a reliable, long-lasting toolset that stays true to fit across multiple applications.
