Vented Stainless Steel Spring-Lock Washers (SI)

We recommend against using regular washers inside a vacuum chamber because they leave small air pockets trapped under them. These pockets can take many months to pump down because of their small gas conductance.

Our vented spring-lock washers have one open end, making them "vented". They lock into place when tightened. This results in quick pumpdown, eliminating the inconvenience of the annoying small gas leaks regular washers cause.
