Definition and Function
A cheater pipe—also known as a cheater bar, snipe, or extension pipe—is a simple yet effective tool used to increase the torque applied to a wrench or breaker bar by increasing the length of the lever arm. It is typically a hollow metal pipe slipped over the handle of a wrench, allowing the user to apply greater turning force with the same effort.
In practice, the longer handle created by the cheater pipe amplifies torque according to the principle of leverage, making it easier to loosen or tighten stubborn bolts, nuts, or threaded pipes that are difficult to move with normal tools.
Primary Uses
Safety Considerations
Using cheater pipes can be hazardous due to the increased force applied, risking:
Safer Alternatives
Practical Tips
A mechanic once struggled removing a stubborn bolt on a heavy earthmover. After snapping several sockets, he carefully fitted a thick steel pipe over his breaker bar, doubling its length. Applying steady pressure, the bolt suddenly freed with a loud pop, but the socket and part of the pipe disintegrated and flew across the shop. Fortunately, no one was injured, and the mechanic shared this cautionary tale to encourage safer tool choices and PPE usage when leveraging cheater pipes.
Conclusion
Cheater pipes remain a practical but risky tool for applying increased torque in heavy equipment maintenance and repair. While they provide mechanical advantage by leveraging physics, their use must be tempered with safety awareness and replaced when possible with modern, controlled torque tools to prevent accidents. Employing cheater pipes judiciously, coupled with correct PPE and tool inspection, helps balance performance needs with workplace safety.

Primary Uses
- Breaking loose seized or rusted fasteners on heavy machinery or piping
- Turning valves or other mechanical components requiring high torque
- Enhancing leverage on ratchets, sockets, or pipe wrenches during maintenance or repair
- Increased Torque: Provides necessary force to overcome tight fasteners without excessive physical strain.
- Versatility: Can be improvised from scrap pipe or purchased as a specialized tool, adjusting length as needed.
- Simple Design: No mechanical parts, easy to use in varied environments.
Safety Considerations
Using cheater pipes can be hazardous due to the increased force applied, risking:
- Sudden breakage or snapping of tools (wrenches, breaker bars, sockets) or fasteners, potentially launching fragments or the pipe itself as projectiles.
- Injury from loss of control when a fastener loosens abruptly.
- Falls or impacts arising from sudden tool movement.
Safer Alternatives
- Impact Wrenches: Pneumatic or electric tools delivering high torque via rotational impacts with controlled force.
- Torque Multipliers: Devices using gear mechanisms to increase torque output without increasing operator effort.
- Pneumatic Torque Wrenches: Combining air power with torque multiplication for precision applications.
Practical Tips
- Always wear personal protective equipment such as gloves, eye protection, and sturdy footwear when using cheater pipes.
- Inspect tools and pipes for cracks, bends, or weaknesses before use.
- Use cheater pipes only on tools rated for the expected torque load.
- Position yourself to avoid the line of impact if the tool or fastener breaks free suddenly.
- Avoid cheater pipes on delicate or calibrated tools like ratchets which may be damaged under high torque.
- Torque: The turning force applied to fasteners or components.
- Lever Arm: Distance from the pivot point (wrench handle) to the point of force application.
- Breaker Bar: A long, non-ratcheting bar used to provide leverage for loosening fasteners.
- Impact Wrench: Power tool delivering torque via rapid rotational impacts.
- Torque Multiplier: Mechanical device increasing torque through gear reduction.
