The Change™-HF protects and outperforms every other HF-Alky gasket on the market.
-Flexibility of a proven spiral wound, low seating stress of a kammprofile.
-Graphite filled like a spiral wound, graphite faced like a kammprofile
-Sigma PTFE inner ring barrier protects the flange from acid corrosion and also fills any existing corrosion damage
-Unique wire profile stores more elastic energy to create better dynamic performance and superior load retention in cyclic applications
-Excellent recovery (tested with 34% recovery @ 18K PSI [124 MPa], 30% compression)
-No spring washers needed, no re-torque required
-Cycle over & over, and maintain sealability
