Sealey 3/8" Drive T Handle and Spark Plug Socket Set 16mm x 21mm

About this tool

The Sealey 3/8" Drive T Handle and Spark Plug Socket Set is a professional spark plug service kit designed for efficient plug removal and installation in automotive maintenance and repair work. This comprehensive set features chrome vanadium spark plug sockets in 16mm and 21mm sizes with a mirror finish, suitable for working with 10mm and 14mm spark plugs commonly found in petrol engines. The rubber-sleeved T-handle bar provides maximum leverage for loosening and tightening spark plugs, whilst the 360° universal joint makes this kit ideal for accessing plugs in confined engine bays where straight-line access is restricted. Internal rubber sleeves in both sockets securely hold spark plugs during removal and installation, preventing accidental drops and protecting the ceramic insulators from damage during handling. This socket set is particularly suitable for mechanics, mobile technicians and vehicle maintenance professionals working across a range of cars, vans and light commercial vehicles. The 3/8" square drive fitment also allows compatibility with standard ratchets and extension bars when required. Features and Benefits: • Chrome vanadium construction with mirror finish for durability and corrosion resistance • T-handle design allows maximum leverage for stubborn spark plugs • 360° universal joint for access in confined engine compartments • Internal rubber sleeves protect spark plug ceramics and prevent drops • Includes both 16mm and 21mm sockets
