DIN first stage dust caps

[Flatliner]

Yoke and DIN dust caps are different




They're not watertight, there's a hole in the end where the string goes through

??? I don't think we have the same caps. I purchased mine because my delrin ones DIDN'T seal the reg correctly. (No relief) I can take a look at them when I get back home but I am pretty sure the hole for the string has no affect on the seal...

Maybe they changed the design. Or I'm confused. Either is possible

I have these ones and I'm pretty sure the hole goes straight through the top into the cavity, rendering them un-water tight
