Prokomon Oxygen Sensor Socket Set 7pc — 3/8" Drive, 7/8" (22mm) Low-Profile Sockets with Side Cutouts

Prokomon 7pcs Oxygen Sensor Socket Set is a low-profile, 3/8"-drive kit designed to remove and install 7/8" oxygen sensors with wiring attached, built from heat-treated chrome vanadium steel.

The Prokomon 7-piece oxygen sensor socket set gives you the specific sizes and shape needed to tackle oxygen sensors and hex vacuum switches on most vehicles. Each socket features a side cutout to clear sensor wiring, a 6-point profile for solid engagement, and a rust-resistant black oxide finish for longer service life. The set works with common 3/8" ratchets, breaker bars, or 1" wrenches so you can access tight or awkward locations without stripping the sensor nut.

How does this set handle oxygen sensors with wiring attached?

The sockets include an 8mm x 64mm side slot that lets the sensor harness remain connected while you turn the nut, removing the need to disconnect fragile wiring. The low-profile, offset design gives clearance around exhaust components so you can work in confined spaces.

• Side cutout allows cable clearance for in-place removal
• Offset compact socket provides extra leverage in tight areas
• 6-point profile reduces risk of rounding fasteners

What materials and corrosion protection are used?

Each piece is made from heat-treated chrome vanadium steel for strength and durability under torque. A black oxide coating helps resist surface rust and maintains a clean finish after repeated use.

• Heat-treated chrome vanadium for long service life
• Black oxide finish for corrosion resistance
• 6-point design distributes force evenly on sensor nuts

Which sizes and drive fitments are included and compatible?

The kit is built around the common 7/8" (22mm) hex oxygen sensor nut and includes a 7mm slot, with sockets at 3-1/10" (80mm) length and a 3/8" square drive. It fits most standard oxygen sensors and works with typical 3/8" ratchets, breaker bars, or 1" wrenches for added versatility.

• Fits 7/8" (22mm) oxygen sensor hex nuts
• 3/8" square drive for ratchets and breaker bars
• 80mm overall length for reach without sacrificing access

Can these sockets be used on different vehicles and sensor types?

Yes — the universal design suits most car and light‑truck oxygen sensors as well as hex vacuum switches. Their sturdy construction and industry-standard sizes make them a practical addition to mechanic and DIY toolkits alike.

• Universal fit for most brands and models
• Works on oxygen sensors and hex vacuum switches
• Durable construction for repeated garage or shop use

Who this is for: The Prokomon 7pcs Oxygen Sensor Socket Set is intended for professional mechanics, backyard automotive enthusiasts, and anyone who needs a reliable tool to remove or install oxygen sensors without cutting harnesses. If you frequently service exhaust components or prefer specialized sockets that protect fasteners and wiring, this compact, corrosion-resistant kit is a practical, affordable upgrade to a general socket collection.
