The method of torque measurement is pivotal in verifying the correct installation of a sealing component, particularly in applications where bolts and fasteners are involved. When a sealing component is installed, it typically relies on the correct fastening of bolts to create a proper seal. The torque applied ensures that the sealing element is compressed adequately against the surfaces it is meant to seal. By measuring the torque, one can confirm whether the fasteners have been tightened to the manufacturer's specified values. This technique not only helps in achieving the necessary compression to prevent leaks but also ensures that the installation is secure, reducing the likelihood of future failures. Correct torque is essential in maintaining the integrity of the seal over time and under varying operational conditions. The other methods, while important in their own contexts, do not specifically address the verification of sealing component installation as directly as torque measurement does. Visual inspection can identify apparent issues, but it may not provide a complete assessment of the seal integrity. Alignment checking is crucial for components that must fit precisely together but does not directly correlate with the proper sealing function. Pressure testing can be effective in assessing leaks once installed, but it is not a direct validation of the installation parameters at the time of assembly. Thus, torque measurement serves as the most reliable method for
