LACO's Open-Style Helium Capillary Leak Standards provide the ultimate in flexibility and customization. Our open-style leak standards use the same robust microtube capillary leak elements as our reservoir-style leak standards but require the end user to provide the helium gas at a prescribed pressure. Open-style leak standards are small in design and can be built into a test part to simulate a "bad part" (leak), or permanently installed in a production leak testing system. See our Leak Standards FAQ for more specifics.
