Lock Technology Shockit Air Hammer Line Wrench

The Lock Technology Shockit Air Hammer Line Wrench line (also called a flare nut wrench or line wrench socket) uses the force and vibration of your air hammer to loosen stubborn fittings. It is made for frozen or hard-to-reach hydraulic and fluid line nuts. It can free fittings on steering, brake, A/C and fuel systems. It also works on heavy equipment such as tractors and forklifts.

Key Features:

• Air hammer powered: An offset, non-turning punch delivers force and vibration straight to the wrench. The vibration helps break fittings free without extensions, ratchets or extra wrenches.
• Interlocking design: The punch locks into the socket so it stays in place while you hammer.
• Slim but strong: Lock Technology says the wrenches use 30% more steel than conventional line wrenches and crows feet. They keep a compact profile for tight spaces between stacked fittings and manifolds.
• Helps protect threads: The vibration-based action loosens fittings without thread galling.
• Precision built: Made to ISO 1174-2 DIN tolerances.
• Patented design and warranty: Covered by U.S. Patent #7,677,143. Lock Technology backs the line with a lifetime warranty against manufacturing defects.

Shockit line wrenches suit professional technicians and heavy-duty maintenance shops. They are a practical way to reach buried line nuts and fittings, and they reduce the risk of rounding fasteners.
