The O-Ring & Engineered Seals Division of Parker Hannifin Corporation has announced the launch of VA179, a new extreme high-temperature fluorocarbon (FKM) compound. VA179 is a 70 durometer rubber seal material, providing increased high-temperature limits while maintaining chemical resistance and low temperature sealing consistent with standard FKMs.
VA179 consists of a rubber technology, increasing the FKM continuous high temperature limit with an additional 20°C over standard FKM materials on the market. This provides a new industry sealing solution to long-term compression set issues for customers using traditional fluorocarbons and silicones.
VA179 provides a wide range of market and application potential with its competitive cost structure, compared to more expensive sealing options. For decades, customers have used more expensive FFKM materials and metal seals for applications requiring temperatures greater than 200°C continuous.
