The O-ring seal is a self sealing structure. As long as the O-ring has initial pressure, it can achieve absolute sealing without leakage. The EPDM seals purchased by Baojie from imported rubber raw materials have good heat resistance, ozone resistance, aging resistance, elasticity, insulation and low temperature resistance, and meet the GB/T 19228.3-2011 international standard.

Compression permanent deformation testing steps

According to the experimental detection results:

The theoretical anti-aging life in 110 ℃ high temperature boiling water is 70 years, and the permanent compression deformation rate is less than 15%. It perfectly adapts to the cold and hot water supply demand of thin-walled stainless steel pipes, and can achieve the same life as the building.
