Reliable Quality
This thermostat is made of high-quality stainless steel and copper materials with high thermal conductivity, high hardness, heat resistance and corrosion resistance. The rubber seal in the middle needs to have a sealing effect, so we used NBR, which is more heat-resistant, corrosion-resistant and oil-resistant. Our seal is thicker, which has good sealing effect.

Advertisement stated it came with gasket. It does not. Only the rubber grommet. Gasket cost me an additional $10.

It fits well, but it got stuck open after the first use. I replaced it with one I purchased from a local marine shop, and it's been working since. Maybe mine was defective. I did not contact customer support, just because of the hassle, though I'm sure a replacement would have been easy.
