Abstract

The selection of the right type of seal material to improve the effectiveness of the leak test machine performance is very important. In addition, standard operating procedures are needed to prevent misuse of the leak test machine which will result in machine damage that hinders the process and increases repair costs. This study aims to (1) obtain a leak test machine design for radiator header leak testing; (2) produce a leak test machine that can be operated for radiator header leak testing; (3) produce a user-friendly standard operating procedure (SOP); (4) determine the type of seal material to improve the performance of the leak test machine. This study is an experimental study. The SOP was prepared and then verified to be tested on 11 participants through a questionnaire. Furthermore, experiments were carried out on 5 types of seals with variations in air pressure of 1-4 Bar with observation and quantitative descriptive analysis. The results of the study show: (1) a leak test machine design is obtained that is suitable for radiator header leak testing; (2) a leak test machine is produced that can be operated for radiator header leak testing; (3) The SOP for the radiator header leak test machine received a feasibility percentage of 84% with the criteria of "Very Feasible" by experts and received a satisfaction percentage of 92% with the criteria of "Very Satisfactory"; (4) the silicone seal material can improve the performance of the leak test machine.
