Leak testing plays an important role in today’s manufacturing environment by ensuring the quality and performance of a product. A critical portion of the leak testing process is sealing the part for pressure or vacuum testing; however, this step is given little attention. And all too often, this is the Achilles’ heel of a poorly conceived leak test process.
Historically, manufacturers relied on wrenching and sealants or the use of jury-rigged clamping fixtures to seal a thread, a tube or a cavity. This is an inefficient, time-consuming process that may damage the product. While this damage may not be immediately evident, it could stress the part that may cause leaks down the road when it is put into customers’ use. Additionally, there are ergonomic concerns with wrenching or other manual clamping associated with this process.
