DanaFlex H Face R633

DanaFlex H Face is designed for flange connections where traditional seals fail due to temperature, chemical degradation or high pressure.
The seal fits into normal O-ring grooves.
Thanks to the heavy spring force provided by the helical spring, it is possible to seal against even the thinnest gases.
