1/2" European oxygen sensor socket — 7/8" (22 mm) slotted design, chrome molybdenum steel Key benefits Durable construction: Made from high-quality chrome molybdenum steel for high strength and resistance to breaking under normal automotive use. Keeps wiring intact: Unique slotted socket lets you remove and install an oxygen sensor while the harness remains connected, reducing the risk of cutting or damaging sensor wires. Reach tight spaces: The slotted, thin-walled design accesses recessed or hard-to-reach sensors where a standard socket cannot fit. Broad compatibility: 7/8" (22 mm) socket size fits most oxygen sensors and is designed to work with any 3/8" drive ratchet or crowbar. Portable and convenient: Lightweight, compact shape stores easily in a toolbox or mobile tool bag for on-the-go repairs. How this solves common problems Avoids harness damage: Remove sensors without disconnecting or splicing the harness, saving time and preventing electrical issues. Makes tight jobs possible: Reaches sensors behind heat shields or close to the exhaust manifold where regular sockets fail. Speeds repairs: Compatible with common 3/8" drive tools so you can use existing ratchets or breaker bars to finish the job quickly. Typical applications Replacing a downstream or upstream oxygen sensor on a vehicle with a recessed sensor port. Mobile or roadside repairs where quick, damage-free sensor removal is required. Home garage or fleet maintenance when you need a compact, reliable tool to service multiple vehicles. Specifications (as provided) Type: 1/2" European oxygen sensor socket Socket size: 7/8" (22 mm) Drive compatibility: Fits any 3/8" drive ratchet or crowbar Material: Chrome molybdenum steel Design: Slotted socket to keep harness connected during sensor removal Practical notes Use with standard 3/8" drive tools.
