What happens if a pipe wrench is too small?

When using a pipe wrench, having the correct size is essential for ensuring a secure grip on the pipe. If the wrench is too small, it may not adequately encompass the pipe. This inadequate fit can lead to ineffective gripping, meaning the wrench cannot apply enough pressure to hold the pipe securely in place. Consequently, this may cause slippage when attempting to turn or torque the pipe for adjustments, fittings, or installations.

While other factors such as a wrench being easy to carry or the potential to damage the pipe are considerations, the primary issue with an undersized wrench is its inability to provide a firm hold. Having a proper fit allows for better control and ensures the wrench can withstand the forces applied during use without losing grip.
