I was looking at my new thermostat and noticed that it did not have an o-ring or gasket. It is a robert shaw 180* and I was wondering do I just reuse the old o-ring or do i need to buy a gasket? Thanks.

buy a gasket they are cheap and simple

thanks! I just checked they have em in stock at my local Napa. Now if I could only fit my truck in the parking lot.

its napa everyone has to come back and warrenty their parts cause they already went bad hahaha
