Line Sockets

Line Sockets for Clean Fitting Service

Line sockets are built for servicing brake, fuel, and hydraulic line fittings where control and access matter. When electrical work requires added protection around energized components, insulated sockets are another option used in certain repair environments. The slotted design fits over tubing while gripping the fastener, helping reduce rounding in tight engine bays or crowded service areas.

Available in several sizes and drive options, line sockets support precise work where standard sockets may not fit properly. For assemblies that use larger retaining hardware, locknut sockets provide another useful solution. When servicing millimeter-based fasteners on many vehicles, metric sockets are also commonly used.
