In terms of the current civil product production technology level, there must be many nodes on the intelligent water segregator o-rings to complete seal, o-rings so material selection is very important. Diversity on the pipe, and the union of the floor heating pipe outlet, due to the impact of hot and cold water, especially water inlet, often at higher temperature, so should choose moderate hardness, high temperature resistant material generally to EPDM is more appropriate.

Intelligent water segregator interface sealing head and valve, because it is a one-off between metal and metal sealing connection, more from the material needs to consider the high temperature resistant performance, generally has a better choose silicone rubber, its heat resistance and anti-aging performance superior to EPDM.

Experiments show that the NBR material, especially carboxyl NBR and hydrogenated NBR, the high temperature resistant and wear resistant ?
