DAYUAN 10-Piece Oxygen Sensor & Oil Pressure Sender Socket Set — Black Oxide, 3/8" & 1/2" Drive, Cutout Sockets

DAYUAN's 10-piece oxygen sensor and oil pressure sender socket set is a professional-grade specialty socket kit made from heat-treated chrome vanadium steel for safely removing and installing O2 sensors, oil pressure sending units, fuel injectors and vacuum switches.

Whether you're a DIY mechanic or a professional technician, this DAYUAN kit gathers the most commonly needed specialty socket sizes in one blow-molded case. The set includes both 3/8" and 1/2" drive options, multiple metric and imperial sizes, and sockets with side cutouts to protect sensor wiring during removal. Each piece is black oxide finished to resist corrosion, and the durable case keeps everything organized on the shelf or in the shop.

Which parts can I remove with this socket set?

This kit is designed for oxygen sensors, oil pressure sending units, some fuel injectors, and vacuum switches on most domestic and many international vehicles. The cutout sockets prevent cable damage when extracting sensors, while the variety of socket lengths reach recessed fittings.

• O2 sensor sockets with cutout sides to avoid wire pinching
• Oil pressure sending unit sizes for common domestic applications
• Long and short socket lengths for tight or recessed installations
• Adapters for both 3/8" and 1/2" drive tools (driver tools not included)

Will these sockets work with my ratchet or breaker bar?

The sockets accept either 3/8" or 1/2" square drives and are intended for hand tools such as ratchets, breaker bars, and hand wrenches. They are not rated for impact-tool use, so avoid air or electric impact guns to prevent damage to the sockets and fasteners.

• 3/8" and 1/2" drive compatibility for common shop tools
• Works with ratchets, breaker bars, and manual wrenches
• Not suitable for impact tools—use manual or non-impact power tools only
• Pairs well with thread chasers when installing new sensors (thread chaser not included)

What materials and finishes protect these tools from wear?

The sockets are heat-treated chrome vanadium steel, chosen for tensile strength and durability under repeated use. A black oxide finish adds corrosion resistance and a low-glare surface that helps in greasy or oily environments.

• Heat-treated chrome vanadium construction for longevity
• Black oxide coating reduces rust and surface wear
• Precision 6PT and 12PT profiles for secure fastener engagement
• Varied socket lengths and sizes to reduce slippage and rounding

How is the set organized and stored?

The kit comes in a blow-molded plastic case sized for bench or toolbox storage with locking latches and a comfortable handle for transport. Molded compartments keep each socket in place so you can grab the right size quickly and return tools to their designated slot.

• Compact blow-molded case with locking latches and carry handle
• Molded interior holds each of the 10 specialty sockets securely
• Case dimensions 11.8 x 9.8 x 2.5 inches for easy shelf or drawer storage
• Quick inventory check—each socket has a dedicated slot

Who this set is for: the DAYUAN 10-piece specialty socket set is ideal for home mechanics, mobile technicians, and shop professionals who service exhaust, engine-sensor, and oil-pressure components. If you frequently remove oxygen sensors, oil pressure senders, or similar threaded components and want a compact, durable kit that protects wires and reaches recessed fittings, this set provides the essential sizes and storage to make those jobs faster and safer.
