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