Gasket??
No Gasket,,, that seems problematic. I'm not sure where you would use this without one and I don't see gaskets anywhere on the site. I could have very easily overlooked it. I'll just source one locally.
Reply from PexUniverse:
Webstone does not include gaskets with their Isolator valves. Gaskets are included with the circulator pump if you're buying a new one. Existing (old/current gaskets) would also work unless they are worn out. If you need new ones, we have 007-007RP available.

Great design makes replacing circulators a breeze
This is a high quality valve. Flange is well machined. I installed two around my two circulators to help make replacement easy. Highly recommend to anyone interested in making repairs easy and quick. Great high quality product.
